    FOREWORD

    THE AMERICAN COMMITTEE for In ternational Wild Life Protection has long been

    interested in encouraging conser vation activ ities in the developing countries. Our

    most recent published reports have dealt with parks and wildlife in Asia and in

    Africa, so we are particularly pleased to add Notes on the Distribution and Status

    of Some Peruvian Mammals  to this series as our fnst on Latin America.

    Peru has rich natural resources of fauna and flora on both the western and the

    eostern slopes of the Andes as well as in the coastal and Amazon regions, with

    the greater part of the terrain at an altitude of over 3,000 meters. This great coun-

    try al so has extensive areas that are still unexplored scientificolly, The existing

    knowledge of Peruvion wildlife is based lorqely on limited collections scattered

    in museums in many parts of the world, and on published reports and government

    records. These notes by

    1 .

    R. Grimwood, who ser ved as Technical Adviser on Wld

    Life for the British Ministry of Overseas Development, on an assignment to the

    Peruvian Servicio Forestal y de Caza, will furnish a useful reference revealing the

    wide gaps in our present know ledge. At the same time this report will, it is hoped,

    encourage ecological research as well as the establishment of appropriate game

    laws, parks, and reserves to help safeguard the endangered and fast-vanishing

    fauna and flora of Peru.

    Readers of this report will also be interested in the proceedings of the Latin

    American Conference on the Conservation of Renewable Natural Resources,organ-

    ized by the International Union for Conservation of Nature and Natural Resources

    and sponsored by UNESCO and F AO, which was held in San Carlos de Bariloche,

    Argentina, March 27 -April 2, 19 68. These proceedings are available from IUCN

    headquarters at 1110 Morges, Switzerland.

    We wish to express our gratitude to Mr. Grimwood for compiling his report on

    Peru and for permitting it to be published by the American Committee. We also

    wish to thank the New York Zoological Society for generously sharing the cost of

    publication.

    INTRODUCT ION

    THE

    INFORMATIONcontained in these notes was compiled during the per iod June

    1965 to May 1967, when 1 was acting as adviser on wildlife conserva tion to the

    Peruvian Servicio Forestal y de Caza, under the United Kingdom-Peru Technical

    Assistance Programme, and 1 a m grateful to the Governments of both countries for

    permission to publish thís pcper.

    These notes are concerned only with the local distribution and current s tatus

    of the larger mammals, exclud ing a11members of the order Chiroptera and covering

    only the super families Chinchilloidea, Cavioidea, and Erethizontoidea of the order

    Rodentia. The notes are a summary of a register containing a11traceable records

    of the occurrence of each species wi thin Peruvian limits, compi led from references

    in the literature, the reports of government and other officials, museum collections,

    hunters' trophies, etc., supplemented by personal observations in the field. At best,

    the available information gives only the barest outline of the current distribution

    and status of the animal concerned, and in many cases nothing is known of a spe-

    cies other than that a lew museum specimens have been collected in a certa in

    loca litY. There are large areas 01 the country which 1 was unable to visit and from

    which no other Iorm01 records is known. Foremost amongst those is the northern

    part 01 the Amazon region, between the Maranon and Amazon rivers and the Ecua-

    dorian and Colombian borders, which remains a blank in my knowledge in regard

    to almost a11 species. It is hoped thot , by highlighting the inadequacy 01 present

    knowledge, thís paper may encourage others to fi ll in the gaps.

    In Peru, the conserva tion 01 terrestrial mammals is the responsibility 01 the Ser-

    vicio forestal y de Caza, while marine mammals (including fresh-water

    íorms

    such

    as the two species 01dolphins lound in the Amazon tributaries) are in the care 01

    the Servicio Pesqueria. When t he Servicio Forestal y de Caza came into being in

    1963, there were no nat iona l parks or reserves to lorm sanctuaries

    íor

    wildlife and

    no regulations controlling hunting, other than a prohibition 01 the killing 01 vicunas,

    fur secls, and sea lions, and a regulat ion prohibiting the killing 01 certain Amazon

    basin forms, including both species 01 peccary and brocket deer, during the period

    December 1 to March 31. The last mentioned regulation was introduced to prevent

    the mass slaughter 01animals when isolated on islands of high ground during the

    annual f100dseason, but it proved to be vírtuo

    lly

    unenforceable. In May 1967 the

    Pampas Galeras National Reserve was created to

    íorm

    a sanctuary for vicuna, and

    the Government is a lso negot iat ing the purchase 01 Hda. Cala Cala as a second

    rese rve for the species, with a view to separa ting the hybrid from the pure-bred

    stock. In March 1968 the

    22,000

    sq. km. ManuNationa l Park was set aside to pre-

    serve representative populat ions of the fauna and flora of the Amazon region in

    their natural state. The Servicio Forestal y de Caza is now selecting areas for the

    creation of national parks in the other two major divisions 01 the country-the

    coastal region and the Andes-and is considering a number of subsidiary reserves

  • 8/18/2019 Notes on the distribution and status of some Peruvian mammals, 1968

    5/49

    or 'sanctuaries to protect certain species which will not be represented in any of

    the three national parks. Regulations íor the control of hunting in the rest of the

    country are also under preparation. Remarks under the heading oí Status in the

    lollowing notes have relevance to those plans , and where poss ible 1have indicated

    íf

    a species is represented in an exis ting or proposed park or reserve and whether

    control of the hunting of it e lsewhere appears to be necessary.

    In describing the distribution of individual genera and species, 1have used the

    terms  coastal region ,  Andean region , and  Amazon region  in referring to

    the three major ecological divisions of the country.

    The coastal region, for the purposes of this paper, comprises the  coastal

    plain  and the  western slopes of the Andes . The coastal pla in, for a lmost its

    entire length, is a sandy desert varying in width from a few kilometers to nearly

    100 km. in the Deportment of Piura and Lamboyeque, which nowhere rises more

    than a few hundred meters above sea level. The annual precipitation, which takes

    the form of winter mists or light drizzle known as  garua , is usua11y under 3 cms.

    The cold Antarctic Humbcldt current responsible for those conditions swings west-

    ward away from the coast at

    cpproxímote

    ly 6.00' S., however: so that from that point

    northward, rainfall gradua11yincreases until it reaches a maximumof approximately

    100 cms. in part s of the Deportrnent of Tumbes. Vegetation in a11but the northern

    part of the coastal plain is confmed to the deltas of the few rivers which run west-

    ward from the Andes, where a var iety of crops, including sugar, cotton , and fruit,

    are grown under irrigation; and to a very few areas where topographical features

    cause an unusua11y high condensation of mist and fog. These areas, which are

    known as  lomas , ha ve a very specialized flora which is usuclly dormant and in-

    visible for the greater part of the year but covers the desert with a complete carpet

    of green-sometimes almost obscured by f1owers-for a few weeks during the winter

    season, between August and November. At 6.00' S. the desert begins to support

    patches of light bush and scrub and the vege tat ion gets progressively richer to the

    north, with trees becoming frequent in drainage lines in the Talara Province of

    Piuro , until i t reaches the stage of true tropical deciduous forest in the Zarumi11a

    Province of the Department of Tumbes. In the north of that Department there are

    also dense mangrove swamps along the shore and on islands in the mouth of the

    Rio Tumbes.

    The  western slopes of the Andes  rise abruptly fromthe coastal pl cín, usually

    as bore rock or gravel slopes which climb steeply, and with scarcely a break, to

    heights of 3,000 or 4,000 meters in many parts. Trees and bushes grow in the few

    valleys containing permanent water, but such natural vegetation has in a11 cases

    been much reduced to make way for human settlement. Sparse grass and other low

    growths appear above 2,700 m., but otherwise there is little vege tation on western

    slopes in the southern two-thirds 01 the country (except íor occasional patches of

    cactus, tillandsia, or other xerophytic plants). At a bout 8.00' S., however , isolated

    areas 01 woodland occur at various altitudes, and those become more and more

    Irequent the lur ther north one goes. Behrendt fo11owsKoepcke in separating such

    woods into (a)  tropical woodland green at the time 01 rain , which occurs at cltí-

    2

    tudes of 600 to 1,000 m.and once covered quite extensive areas in the Departments

    of La Libertad and Lambayeque belore most oí it was destroyed by settlement;

    (b)  sub-tropical deciduous woodland  occurr ing in widely scattered patches from

    altitudes of 1,000 to 2,400 m., which he likens to the  ceja de selva zone on the

    ecstern slopes oí the Andes; and (e) temperate evergreen woods  which are íound

    at altitudes 01 lrom 2,400 to 3,300 m. in a lew places north of 7.00' S.

    Since 1have included the western and eastern slopes of the Andes in the coastal

    and Amazon regions respectively, íor the purposes oí this paper, the Andean region

    remains as the mass of high ground between the two. The greater part of that mass

    lies at over 3,000 m. and is rather like a couched, but smcll, humped camel in formo

    The broad mass of the camel's hindquarters lies in the south, wi th the ridges of

    land over 4,500 m. representing its hip bones; its hump and withers are represented

    by the single ridge of mountains, reaching heights of over 5,500 m., wh ich runs

    through the Departments of Lima and Ancash. The high ground then falls away

    and narrows to the dip of the camel's neck at 6.00' S., where the Andes can be

    crossed by a pass oí no more than 2,144 m. in he ight; from this point the narrow

    neck gradua11yrises again to a head which would he somewhere on the Colombícn-

    Ecuadorian border.

    1 have used the terms  puna ,  sierras , and cordilleras  in referring to the

    different ecological zones of the Andean region. By  puna , 1 mean the extensive

    areas of genera11y level, sour, short grassland which are íound at alt itudes of from

    3,800 to 4,300 m. between the main eastern cnd western mountain ranges, írom

    Lake Titicaca in the south to a li tt le north of Lake Junin (11.00' S.). The puna

    zone is not a continuous stretch of country, but consists of a number of plateaus

    divided from each other by intervening mountains, and which are much cut up by

    deep gorges. The puna zone is extensively used for grazing llamas, alpacas,

    sheep, catt le , and horses; but the only agriculture practised is the planting of sma11

    patches of potatoes. Precipitation is not great and usually takes the íorm of short

    but heavy ra in or ha il storms. Snow is rare. A simila r, but drier , type oí country

    occurs at somewhat lower altitudes between 9.00' S. and 7.00' S., where it is known

    as  jalna .

    1have used the term cordilleras  for the ranges of mountains which rise above

    the general level of the Andean platea u to heights of 5,500 m. or more

    (í .e., prín-

    cipally the hips and hump oí the camel) and which are usually capped with glaciers

    or permanent snow. At over 5,000 m. the slopes of the cordilleras are devoid of

    vegetation, but the lower valleys often contain dense thickets or smcll woods oí

    Polylepis

    spp.

    The word  sierras  has been used as a general term for the system of deep

    valleys and intervening ridges which occur throughout the Andean region and which

    carry almost half the total papulation of the entire country. In most parts of the

    sists of no more than a few bushes or shrubs growing on cliffs or slopes so steep

    ihot even goats are unable to reoch them.

    1 have included under the term  Amazon region 011 that part of Peru lying to

    the east of the eastern rim of the Andes-Le., that part of the country which is

    directly affected by the Atlantic climate. Rainfall is high, and the Amazon region

    is uniformly íorest-clcd from tree line at between 3,000 and 3 ,400 m., down to the

    banks oí the Amazon, at just over 100 m. In the south, particulorly in the Deport-

    ments ol Puno and Cuzco , the transition írom 3, 00 0 to 500 m. is abrupt and takes

    the forrn oí a single escarpment; but in the north the process is more gentle, and

    in the Depar tments oí San Martin and Amazonas there are considerable oreas oí

    broken ground at an elevation oí between

    2,0 00

    and

    1 ,00 0

    m. beíore the lower level

    is reached. Below 500 m. slopes ore everywhere less pronounced, and there is

    often J íorrnless pattern oí low

    lls and ridges beíore the true va11ey bottoms ore

    reached. Neor ly a11 the rivers oí the Amazon region ílow north and east to where

    the Rio Moranon and the Rio Ucayali unite to Iorrn the Amazon river, but the south-

    ernmost part oí the region lies in the basins oí the Rio Purus and the Rio Madre

    de Dios, which drain southword and eastword belore describing an are to join the

    Amazon halfway down its course to the Atlantic Ocean. Most oí the rivers are con-

    tained within their banks throughout their upper courses, but in their lower reaches

    they overf low and inunda te vast oreas oí land each rainy season, a lact which al-

    íects the distribution oí many mammals. As that low-Iyinq ground is slow to drain,

    extensive systems oí permanent tree-shoded lagoons, creeks, and oxbows ore csso-

    ciated with the lower reaches oí the Rios Madre de Dios, Ucayali, Huallaga, Mora-

    non, Tigre, Napo, and Ycvorí, but there is no open swampland. The Amazon lorests

    represent a series of inadequately known or understood ecosystems, which 1 ha ve

    somewhat a rbitrarily divided into three zones: the  ceja de selva zone , the  high

    selva zone , and the  low selva zone .

    The name  ceja de selva  (Iítero lly  the eyebrow of the íorest ) is widely

    used to describe the upper limits oí the íorest. In most cases they cover steep

    and broken slopes and consist of deciduous semi-tropical woodland, which may

    extend right to the top oí the e scorpment. Where the escorpment is high, however,

    there is often an upper belt oí temperate woodland, which in turn gives place to

    bush and scrub, and eventua11y to grassland, belore the top is reached. As 1 have

    used the term, such temperate woodland, as we11 as bush and scrub zones, are in-

    cluded in the ceja de selva zone. Its lower limit is more diíficult to define, but for

    the purposes oí this paper it can be taken to he at about 2, 50 0 m.

    The  high selva zone  covers a11 that part oí the region lying below the ceja

    de selva zone and above 50 0 m., and it is comprised principa11y of semi-tropical

    lorests of one type or another. 1 h ave chosen 500 m. as the dividing line between

    the high and low selva zones on geographical rather than ecological grounds, as it

    morks the íoot oí the main Andean escorpment; but it does coincide with the limit

    of distribution of a number of species.

    The  low selva zone  comprises 011 that part of the Amazon region lying below

    500 m., including the better drained ·ground along the íoot of the Andes and along

    4

    th e Brazilian and Ecuadorian borders, as we11 as the low-lying land subject to

    annual inundation which is found in the lower bas ins of the major r ivers.

    In giving the known distribution of genera and species, 1 have in almost al

    cases quoted records by Provinces rather than exact localities, Ior the sake al

    brevity and because greater accuracy seems unnecessory in a poper oí thi s nature.

    In the case oí the Department of Loreto, however, where Provinces are enormous,

    1 have reíerred to the river valley in which specimens were taken or observations

    made. This gives suíficient accuracy, since íew records exist from place s more

    than a lew kilometers írorn the banks of rivers, which Iorrn the only means oí tro-

    versing the country.

    1 ha ve relerred to both specimens  and  reliable reports  in recording the

    occurrence oí individual species, and ha ve accepted both as evidence oí the pre-

    sence oí an animal in a given orea. Under  specimens  1 have included known

    museum specimens; other specimens co11ected by me; relerences to specimens in

    the literature; skins, heads, or other troph ie s seen in the houses oí local hunters

    or others; and, in one or two cases, hunters' photographs

    0 1

    newly kil ed animals.

    Museum specimens include those in the Museo de Histo ria Natur al  Javie r P rado 

    oí Lima, and in a number oí university co11ections in vorious Peruvian towns, as

    well as those in some other museums; but principally those in the British Museum

    (Natural History), the Fíeld Museum al Natural History (Chíccqo), and the American

    Museum oí Natural History (New York) - to the staffs oí all oí which 1 wish to

    record my gratitude íor the ir k indness and help.

    When 1 ha ve stated that an animal is  r eliably reported  to occur in a certain

    loca lit y , it means in nearly a11 cases that 1 have personally visited that loca lit y

    and have satisfied myself oí its presence by questioning local residents and

    hunters, often being able to confirrn their statements by seeing tracks or other

    signs. 1 have, however, in cluded reports írorn the relerences quoted at the end oí

    this poper; and, in the case of the valley of the upper Rio Moranon and the north

    oí the Department oí San Mortin, 1 have ava iled myself of the knowledge oí Sr. Jose

    Linoresoí the Servicio Forestal y de Caza, who spent more than 20 yeors working

    in the lorests of that region and whose ass ist ance 1 qrcteíully acknowledge. Per-

    sonal sight r ecord s oí living animals are usually quoted as such.

    Except where otherwise stated, 1 have throughout lol1owed the nomenclature

    used by Cabrera. -I.R.G.

    DIDELPHIDAE

    Genus

    Ca/uromys

    J.

    A

    Allen - WoollyOpossurns

    Local Names.- None known.

    Distribution.- Opossums, other than members of the genus

    Didelpbis,

    are rarely

    observed in the wild. Knowledge of their distribution is therefare largely based

    on the result s of museum collecting, which has been carried out in only a few

    ports of Peru. Specimens of

    Caluromys

    are, however , known froma large nurn-

    ber of localities in the Amazon region, from 4.00' S. to 13.50' S., .ct a lt itudes of

    from 150 to at least 500 m. It is therefore probable that the s ingle Peruvian

    species of this genus occurs in suitable areas throughout the low selva and

    probably in the lower levels of the high selva as well.

    Taxonomy.- The species is

    Caluromys lanatus

    (Illige r) throughout, and Cabrera

    attributes Peruvian specimens to the roce C.

    l. ornatus

    (Tschudi).

    Status.- The spec ies appears to be fai rly commonas well as widespread. A small

    number of live specimens are exported fromIquitos ecch year, but woolly opos-

    sums are not known to be hunted ei the r fa r food or fa r thei r fur, and they can be

    but little affec ted by dest ruction of habitat consequent on settlement. There is

    therefore no reason to consider them in any way endangered. The species is

    represented in the ManuNational Park .

    Genus

    Ca/uromysiops

    Sanborn - Black-shouldered Opossums

    Local Names.- None known.

    Distribution.-

    Caluromysiops irrupta

    Sanborn, the single spec ies of this genus,

    was discovered in 1950 and so far as is known only froma few specirnens , al 

    taken below 700 m. in Quispicanchis and Paucartambo Provinces of the Oeport-

    ment of Cuzco and the Manu Province of the Oepartment of Madre de Dios.

    Status.- The area fromwhich

    it

    is known is l it tle inhabited, so this species is not

    endangered by mano Sr. C. Kalinowski, i ts discoverer, infarmed me that he had

    recently collected a specimen on the Rio Alto Madre de Dios, so the species

    maywel l be present in the ManuNational Park.

    Genus

    Glironia

    Thomas - Bushy-tailed Opossums

    1 have been able to d iscover nothing of the status of either of the two species of

    thi s genus, both of which were described from Peru: G.

    criniger

    Anthony from

    the confluence of the Rios Curaray and Napa, in the Oeportment of Lareto; and

    G.

    uenusta

    Thomas fromPozuzo, in the Deportrnent of Huanuco.

    Genus

    Monodelphis

    Burnett - Short Bare-tailed Opossums

    Monodelphis adusta

    (Thomas) is the only member of this genus recarded by Cabrero

    as occurring in Peru, where he gives the range of  Peru east of the Andes  far

    the roce M  

    a. peruuiana

    (Osqood) . 1 have nothing to recard on either the distri-

    but ion or the sta tus of thi s species, other than that Soukup refers to specimens

    from the Ocobamba valley, La Convencion Province, Department of Cuzco, and

    from Pucallpa in the Department of Loreto, in addition to Moyobamba, in the

    Department o f San Martin , f rom where the Peruv ian roce was fir st described.

    Genus Marmosa Gray - Mouse Opossums

    Mouse opossums are widespread in the low selva, high selva, and ceja de selva

    zones throughou t the Amazon r egion , and ind ividuals can often be seen or heard

    at night. Cabrera recognizes no less than 12 species as occurring in that region,

    however ( three o t th em represented by more than one roce), and their separation

    is almost impossible in the field. Adequate knowledge of the status and distrí-

    bution of individual species can therefore be gained only by very extensive col-

    lecting. Because of their small size and nocturnal and mainly arbo real hab its,

    mouse opossums are not directly threatened by man, but some of the high al ti-

    tude species may be endangered by the widespreod clearing of bush .which is

    taking place in parts of the ceja de selva and in wooded valleys of the Andes ,

    and likewise by the domestic cats of settlers in tho se par ts. Besídes the 12

    species of the Amazon region, a thirteenth species, Marmosa robinsoni Bangs,

    occurs to the west of the Andes in the extreme north of the coun tr y.

    Genus Philander Tiedemann - Grey Four -eyed Opossums

    Distribution.- Specimens of Pbilander have been taken near Iquitos and from a

    number of localities in the Ucayali and Huallaga valleys, and on the Rio Curanja

    at approximately 71.30' W., 10.20' S., in the Department of Loreto. Specimens

    are also known from Moyobambo Province of the Department of San Martin, the

    Oxapampa Province of the Depcrtrnent of Pesco, and the Quispicanchis Province

    of the Depcrtrnent of Cuzco, at altitudes up to 1,500 m. It is therefore proboble

    that this opossum occurs in the low selva zone and in the lower part of the high

    selva zone throughout the Amazon region.

    Taxonomy.-

    Pbilander opossum

    (L inn.) is the only species of the genus. Accord-

    ing to Cabrera, the form at lower alt itudes is P. o. andersoni (Osgood), for which

    Yurimaguas (Dept. of Loreto) is the type locality; spec imens f rom higher levels

    belong to the race P. o. canus (Osqood) . which was described from Moyobombo.

    Status.- Similar to that of

    Caluromys lanatus.

    Genus Metachirus Burmeister - Brown Four-eyed Opossums

    Distribution.-Specimens of

    Metachirus nudicaudatus

    (E. Geoff roy ), the on ly spe-

    cies of the genus, are known from a number of localities in the Ucayali valley

    and from the Río Curanja at approximately 71.30' W., 10.20' S., in the Deportrnent

    of Loreto, and from higher ground in the Provinces o f Chachapoyas (Amazonas) ,

    Moyobombo (San Martin), Tingo Maria (Hucnuco), La Convencion (Cuzco), and

    Carabaya (Puno), at altitudes of up to at least 1,200 m. Like Pbilander opos-

    sum

    and

    Caluromys lanatus,

    t he species is therefore l.kely to be found in the

    low selva zone and the lower part of the high selva zone, throughout the Ama-

    zon region.

    8

    Taxonomy_-According to Cabrera,

    M.n: boZivianus

    J. A. Allen is the roce in the

    south of the country; it is replaced by M .

    n. tscbudii

    J. A. Allen (descr ibed from

    Guayabambo in the Depar tment of Amazonas) in the centre and north.

    Status.- Similar to that of Caluromys lanatus.

    Genus Didelphis Linn - Common Opossums

    Local Names.- Muca, Intuto, Overo, Raposa, Carachupo, Comedreja.

    Distribution.- Opossums of this genus are perhaps the most ubiqu itous and com-

    mon of all Peruvian mammais, being found in all three r egions of the coost, the

    Andes, and the Amozon basin, from the north to the south of the country. In the

    coastal region they occur in the cultivated valleys and other vegetated areas of

    the western slopes of the Andes, while in the Andes themselves they are to be

    found in almost every valley of the sierra zone; and 1 have found the corpse of

    one run over by a car at 4,000 m. They reach their greatest numbers in the ceja

    de selva and high selva zones of the Amazon region, but they also occur in the

    low selva, where specimens ha ve been taken on the lower Rio Ucayali and on

    the Rio Curanja near to the BraziÍian border.

    Taxonomy.- Both

    Didelphis marsupiali s

    Linn. and

    Didelphis

    azarae Temminck

    are found in Peru, but the two species are diíficul t to distinguish in the field.

    D. marsupialis appears to be restricted to the northern part of the country, and

    the southernmost museum-ídentífied specimens of which 1 am aware came from

    the Deportrnent of La Libertad. D. azarae , on the other hand, has been reco rded

    from the north to the south of the country. It is not known

    i f

    D.

    marsupialis

    reaches the same altitudes as D. azarae in areas where their ranges overlap.

    D.

    marsupialis

    occurs in its nominate form, while D.

    azarae

    is represented by

    the race

    pemigra

    J. A. Allen, of which Minas delInca (Deportr nent of Cuzco) is

    the type loca lit y .

    Status.- Both species of this genus ha ve a bod reputation for poultry killing. They

    are in no need of protection, howevet, and are well able to look after themselves,

    even in quite heavily settled areas. D. azarae is present in the Manu Nat ional

    Park.

    Genus

    Chironectes

    I lIiger - Yapoks or Water Opossums

    Local Name.- Raton de Agua.

    Distribution.- The single species of this genus probably occurs in the low selva

    zone and the lower parts of the high selva zone, th roughout the Amazon region,

    as it is known by specimens or reliable reports from Pucallpa, on the Rio Uco-

    yali, and from the Rio Curanja near the Brazilian border, in the Depcrtment of

    Loreto; and from higher ground in the Provinces of Moyobambo (San Martin),

    Tingo Maria and Pachitea (Hucnuco), Tarma (Junín). Quispicanchis (Cuzco),

    Manu (Madre de Dios), and Caraba ya (Puno). Its pre fe rred habit at appears to

    be the banks of small streams and quebradas, where the water is usually clearer

    and less deep than in the larger rivers. Its upper altitudinal limit is not known,

    but 1 k now of one animal being killed at 900 m.

    9/49

    Taxonomy.- The species is Cbironectes minimus (Zimmermann), of which the roce

    panamensis Goldman probably occurs throughout.

    Status.- Although previously considered worthless, the skins of this opossum are

    now beg inning to command a price, and in 1966 Iquitos and Pucallpo merchants

    wer e poying fr om Soles/lOO to S/2oo each for them (S/75 = O). Intensive com-

    mercial hunting could as readily reduce this species as it has the giant otter

    (Pteronura brasiliensisi.

    have beenable to discover nothing of the status of any of the species of the

    genus Caenolestes Thomas which are recorded as occurring in the north of Peru;

    but as they are confmed to the heavily settled Andean region, they may be

    thr eatened by ex tensive destr uction o f hab itat.

    The same remorks apply to Lestores inca Thomas, which is so far known only from

    PRIMATES

    WITHIN Peruv ian lim its, primates are found only in the Amazon region, with the

    exception of the genero Alouatta and Cebus, both of which also occur to the west

    of the Andes in the forested ports of the Zarumilla Province of the Department of

    Tumbes.

    Besides being intensively hunted for foad by indigenous Indians and settlers

    alike-for the flesh of most species is highly esteemed-primates are subject to

    a fo rm of explo itation not suf fered by other an imals: that is, the capture and export

    of l o r q é numbers for medical research purposes and for the pet trade. Over 139,000

    were expor ted a live between 1961 and 1965; 17,687 of them in 1961,27,095 in 1962,

    35,635 in 1963, 34,345 in 1964, and 24,382 in 1966. A breakdown of the 1964 total

    into genera is given below. The price shown against each genus -is the price paid

    in Soles for l ive spec imens reaching Iquitos (1966 values).

    It is thought that, even in the case of the most robust species, four or

    five

    in-

    dividuals must die in the course of capture or during the long canoe journey to

    Iquitos, or while being held there, for every one tha t survives to be exported; and

    the low prices poid for Alouatta and Leontocebus reflect the high mor ta li ty of

    animals of those genera during even the few days that dealers have to hold them

    between weekly export flights.

    It is díff icult to cssess- the effect of this f orm of exploitation, but it is thought

    that, even allowing for casualties, the number of individua ls taken for export can

    be only a fraction of the number ki11ed for foad, in the case of most species. The

    combined effect of a11 forms of hunting has been, however, almost to el imina te a11

    forms of primates within a radius of many kilometers of settlement or of the rivers

    which constitute the highways of the region. The radius of destruction is increas-

    ing yearly, with professional hun ters and tr appers push ing further into virgin coun-

    try, and with hunting by remote Indian tribes becoming commercialized as a result

    of the visits of skin and live animal dealers. The survival of many species now

    seems to depend on how much of their natural territory will remain inaccessible to

    waterborne hunters.

    Control of the hunting of a11 primates is therefore necessary, as is control of

    the capture and export of live specimens. The latter measures should be framed to

    eliminate the cruelty from which captive animals now suffer as well as to conserve

    the species in the wild.

    CEBIDAE

    Genus Aotus IIliger - Dourocoulis or Night Monkeys

    Local Names.-

    Musmuqui, MonoNocturno, Pi-to (Campa).

    Distribution.-

    Specimens

    01

    the s ingle species of this genus are known from Iqui-

    tos, the Rio Yavari Mirim, several localities on the Rio Ucayali, and the Rio

    Curanja, in the Department of Loreto; and from the Provinces

    01

    Chachapoyas

    (Amazonas), Tingo Maria and Pachitea (Huonuco), Tarma (Junin) , Huanta (Aya-

    cucho), Quispicanchis (Cuzco), and Sandia (Puno). In addition it is reliably

    reported to occur in many places in the Department 01 San Martin and in both

    the Manu and Tambopata Prcvinces 01 the Department 01 Madre de Dios. Those

    record s cover an altitudinal range

    01

    írom 150 to 1,000 rn., and according to

    Walker

    et al.,

    it has been recorded up to 2,100 m. The species therelore prob-

    ably occurs throughout the lowselva zone and the lower levels of the high selva

    zone.

    Taxonomy.-

    The species is

    Aotus trivirgatus

    (Humboldt). Cabrera recognizes the

    race

    A. t. vociferans

    (Spix) as occurring in the north, but Osman Hill (1960) re-

    gards that formas inseparable from A. t.

    triuirgatus.

    Both authorities recognize

    the race A.

    t. nigriceps

    Do11man(type locality Chanchamayo, Dept. oí Junin) as

    the high altitude Iorrn occurring along the eastern slopes 01 the Andes.

    Status.-

    The nocturnal habits

    01

    this species probably afford it adequate protec-

    tion from hunting, and it is rarely taken unless found in a hollow tree when cut

    down. Although found only in family parties, it is widespread and reasonably

    abundant. It is adaptable to a variety of habitats, and escaped specimens are

    even breeding in the vicinity of Lima.

    Aotus triuirgatus

    is present in the Manu

    National Park.

    Genus Callicebus Thomas - Widow Monkeys or Titis

    Local Names.-

    Tocon, Tacare (Campa).

    Distribut ion and Taxonomy.-

    This genus has been recorded from almost every port

    01 the low selva zone of the Amazon region, but it scarcely enters the high

    selva zone , as no record is known íromabove 850 m. altitude. Peruvian speci-

    mens have been attributed to a variety of species in the post, and to an even

    greater number of roces. Hershkovitz (1963), in his masterly review of the

    genus, has greatly

    clorífied

    the picture. He recognizes only two species as

    occurring within Peruvian limits:

    Callicebus torquatus

    (Hoffmannsegg), which

    is found only on the left bank of the Amazon river between the Rio Tigre and

    the Rio Putumayo (Irom where it extends into Colombia as lar as the Rio Ca-

    quetc): and

    Callicebus moloch

    (Hoffrncnnseqq), which occurs throughout the low

    selva except on the left bank of the Amazon river between the Rio Napoand the

    Rio Putumayo. The two species are therefore only sympotric in the small area

    between the Rio Tigre and the Rio Napo.

    12

    Hershkovitz considers

    Callicebus torquatus

    to occur in its nominate form,

    and cites specimens from the Rio Nanay , the Rio Yahuas (the Yaguas tributary

    of the Putumayo?), and the Rio Putumayo. He recognizes only three races of

    Callicebus moloch

    as occurr ing within Peruvian limits:

    C.

    m cupreus

    Spix, with a ronge

    01

    from the Rio Yavari westward to the mouth

    oí the Rio Ucaya li , o fwhich he cites specimens from the Rio Maniti, San

    Fernando on the Rio Yavari, and the Rio Yavari-Mirim.

    C. m

    discolor

    1. Geoffroy (type locality Sarayacu, Rio Ucayali), occupying

    the rest of the northem part of the low selva zone, to as lar south as

    approximately 10.00' S., of which he ci tes specimens fromthe Rio Nanay,

    the Rio Pastaza, and the Rio Maranon; Santa Cruz on the R ío Hua11aga;

    Saroyacu, Cashiboya, Cerro Azul, Yarinacocha, and

    Cumarío

    on the Rio

    Ucayali (a11in the Deportment of Loreto) ; and from Moyobamba (820 m.)

    and Yuracyacu (787 m.) in the Deportment of San Martin; Tingo Maria

    (610 m.) and Pachitea (c irca 150 m.) in the Deportment of Huanuco ; and

    Puerto Victoria on the Rio Pachitea in the Deportment of Poseo.

    C. m

    brurmeus

    Wagner, occurring in the Department of Madre de Dios and in

    those ports of the Depar tments of Puno and Cuzco which lie in the Ama-

    zon region, at altitudes up to 650 m., of which he cites specimens from

    Marcapota (Dept. of Cuzco) and Condamo

    (Río

    Tambopota, Dept. of

    Puno),

    Dr. A. L. Gardner also collected specimens of C.

    moloch

    on the Rio Curonja

    in 1966, which should be of interest in determining the meet ing point oi the last

    mentioned two races.

    Status.-

    1 know nothing of the status of C.

    torquatus.

    C.

    moloch

    is nowhere as

    common as

    Saimiri sciureus

    or

    Cebus apella,

    and ís Iound in much smaller par-

    ties, usually of less than ten individucls. It also occupies a smaller range

    beca use oí its rest ric tion to lower altitudes. Within that range, however, it is

    widespread and still to be found in most areas away from the vicinity of settle-

    mento The species therefore cannot be considered as endangered. C.

    moloch

    is present in the ManuNational Park.

    Genus Cacajao L es so n - Uakar is

    Local

    Names.-Huapo Colorado , Mono Ingles, Puca Huapo.

    Distribution.-

    The only species oí this genus to occur in Peru is confmed to the

    northeast comer of the Amazon reqion, where it is found to the north of the

    Amazon river in the basins of the

    R ío

    Napa and the Rio Putumayo, and to the

    south oí it in the basins oí the Rio Ucaya li and the

    R ío

    11/49

    Taxonomy. - The species is

    Cacajao rubicundus

    1. Geoffray and Oeville, which

    occurs in the nominate form in the Napa basin. The race C.

    r. ucayali

    Thomas

    was created for specimens from Cerro Azul, which is the southernmost localit y

    from which the species is known.

    Status.- I have no personal knowledge of

    Cacajao rubicundus

    in the field, but it

    is said to be now everywhere rare and declining in numbers. The cause of its

    decline is undoubtedly hunting, for it is easy to kill and its f1esh is highly

    esteemed. The number of animals captured for export may also have s iqnífi-

    cant ly a ffected the sta tus of this species, which has a very poor record of sur-

    vival in captivity. Both the capture of it and the killing of it should be total ly

    prohibited.

    Cacajao rubicundus

    does not occur in the Manu National Par k , nor

    does it appear to be known in the Rio Samiria port of the proposed Rio Samiria

    and Rio Pacaya Reserve. It is possible, however, that it will be found in the

    Río Pacaya end of that reserve.

    Genus

    Pithecia

    Desmarest - Saki Monkeys

    Local Names.- Huapo Negro, Yana Hucpo , Jero (Campa).

    Distribution.- The only Peruvian species oí this genus is confmed to the low

    selva zone, and 1 have no record of its occurrence at over 60 0 m. lt is known

    by specimens from the Rios Yavari, Maniti, Maranon , Ucayal i, and Curanja, in

    the Department of Loreto; and from the Provinces of Pachitea (Huanuco) and

    Manu (Madre de Dios). It is also reliably reported from a number of localities

    in both the north and the south of the Department of San Martin. It is therefore

    probably to be found in suitable localities throughout the low selva zone.

    Taxonomy.- The species is

    Pithecia monacbus

    (Geoffroy), which is represented

    by the nominate race throughout.

    Status.- This species is generally less common than

    Callicebus moloch,

    and it

    is usua11y to be found only in small family parties. It has been exterminated

    everywhere near to settlement and to those rivers carrying heavy troff ic, but i t

    still occurs in fair numbers elsewhere.

    Pithecia monacbus

    is present in the

    ManuNational Park.

    Genus

    Alouatta

    Lacepede - Howler Monkeys

    Local Names.- Coto , Coto Mono, Shianonte (Cornpc) , Numii (Chcyhuito), Omecoy

    (Achual).

    Distribution and Taxonomy.- It is probable that two species of this genus occur

    in Peru.

    The reddish-colored

    Alouatta seniculus

    (Linn.) is known by specimens or

    rel iable reports from the Rios Nepe, Maranon, Huallaga, Ucayali, and Curanja,

    in the Department of Loreto; and from the Provinces of San Martinand Mariscal

    Caceres (San Martin); Tingo Maria and Pachitea (Huanuco); Oxapampa (Pesco):

    Jauja (Jun in); La Convencion, Paucartambo, and Quispicanchis (Cuzco); Sandia

    (Puno); and Manu (Madre de Dios). These records cover a range of from 200 m.

    to 1 ,2 00 m. It is therefore probable that this species occurs throughout the low

    14

    selva zone and in the lower part of the high selva zone, from the north to the

    south of the country. It is represented by the nominate race throughout.

    Some form of

    Alouatta

    is also locally reported to occur to the west of the

    Andes in the Zarumilla Province of the Department of Tumbes. I have not seen

    the animal myself, nor do I know of any specimen having been collected. It is

    universally said to be block in color, however, so could poss ibly be

    Alouatta

    palliata

    (Gray), of which the roce A.

    p. aequatorialis

    Festa is known to occur

    on the coast of Ecuador some way to the north.

    Status.-

    Alouatta seniculus

    is hunted for Iood, but íts f1esh is not highly esteemed.

    It has disappeared from t he vicinity of 011settlement and from the banks of the

    major rivers, where its habit of coming down to drink in the middle of the day

    makes it particularly vulnerable. In other areas the species still seems to be

    fairly common and can be found in parties of up to 25 indi víducls, although I

    have nowhere found it as abundant as it is in the northern end of its range in

    Colombia. However, the ease with which the presence of this species can be

    detected by its loud call s at morning and evening (and by its strong smell, on

    occasions) may give a false impression of its abundance relative to other mon-

    keys. The fact that the species is not restricted to the low country means rhct

    some parts of its range remain undisturbed by water borne hunters.

    Alouatta

    seniculus

    is present in the ManuNational Park.

    I know httle of the status of the coastal representative of this qenus , but

    the area it occupies is comporctively smcll and is much visited by hunters.

    Genus

    Cebus

    Erxleben - Capuchin Monkeys

    The two species of this genus that occur in Peru are treated separately below.

    Cebus apella

    (linn.) - Brown or Tufted Capuchin Monkey

    Local Names.- Machin Negro, MonoNegro, Yana Machin, Shito (Campa).

    Distribution.- This species is confined to the Amazon region, where it is known by

    specimens or reliable reports fromalmost a11parts of the Department of Loreto;

    and from the Provinces of Moyobamba, San Martin, and Mariscal Caceres (San

    Martin.); Chachapoyas (Amazonas); Tingo Maria and Pachitea

    (Hucnuco):

    Oxo-

    pompo (Pesco): Tarma (Junin); La Convención, Paucartambo, and Quispicanchis

    (Cuzco); Sandia (Puno); and Manuand Tornbopoto (Madre de Dios). A specimen

    from 40 miles east of Chachapoyas was taken at just over 1,500 rn., and the

    species is loca11y reported to occur at over

    1 ,40 0

    m. in the Oxcpcrnpo Province

    and in several localities in the Paucartambo and Quispicanchis Provinces. It

    therefore seems probable that

    Cebus apella

    occurs throughout the low selva

    zone and up to about 1 ,50 0 m. in the high selva zone, from the north to the south

    of the country.

    Taxonomy.- Osman Hi11recognizes four roces of C.

    apella

    as occurring in Peru:

    c.

    a macrocepbalus

    Spix in the main Amazon valley, extending as far west as

    Chachapoyas; C.

    a [atuellus

    (Linn.), possibly occurring on the eastern slopes

    of the Andes in the extreme north; C.

    a maronensis

    von Pusch (type locality

    15

    12/49

    Hamburgo, on the Rio Samiria), to the south of C.

    a. macrocepbalus ;

    and C.

    a.

    peruanus Thomas (type loca lit y Marcapata, Oept. of Cuzco). in the extreme

    south , in the Oepartments of Cuzco, Puno, and Madre de Dios. In Cabrera's

    view, however, C.

    a.

    [atuellus , C.

    a.maronensi s ,

    and C.

    a. peruanus

    are insepar-

    able from C. a. macrocephalus, which he therefore regards as the form throughout.

    Status.- Besides being one of the most widespread of Peruvian monkeys, Cebus

    apella is also one of the commonest, being almost equal to Saimiri sciureus in

    general abundance. Like that species, if has not who11y disappeared from a11

    areas of settlement, and it is frequently accused of raiding crops and gardens.

    It, too, is found in large parties of up to 30 individuals. Together with Saimiri

    sciureus,

    this species forms the basis of the export trade in live monkeys for

    medical research purposes; and of the 2,574 animals of that genus tha t were

    exported in 1964, 2,518 were recorded as being C.

    apella.

    (Those figures are

    unlikely to be accurate because both species of Cebus are often lumped together

    for trade purposes. At least 90% of a11

    Cebus

    seen in holding pens awaiting

    export havebeen of this species, however.) Only young animals are exported,

    any adult specimens that are caught presumably being

    killed,

    Oespite the dr ain

    on numbers represented by both capture operations and hunting for food, the

    species is in no danger of extinction and is sti11 abundant in most parts of its

    range.

    Cebus apella

    is present in the Manu National Park.

    Cebus a bifrons (Hu mb old t) - White-fronted Capuchin Monkey

    Local Names.- Mach in Blanco, Yurac Machin, Cochire.

    Distribution.- This species is found in the Amazon region, and almost certainly

    occurs in the coostal region as well. In the Amazon region, C. albifrons occu-

    pies the same over-a11 range as C. apella. Its local distribution is patchy, how-

    ever, and it is apparently absent from many areas where the latter species is

    common. In general. it is reported not to occur at quite such high altitudes as

    C. apella, but a specimen is known fram 1,500 m. on the Rio Cosireni, La Con-

    vencion Province, Oepartment of Cuzco.

    In the coastal region, some form of  machin  is locally reported to be p re-

    sent thraughout the forested parts of the Zarumi11a Prav ince of the Oepartment

    of Tumbes. As far as 1 am aware, no specimen of it has ever been critica11y

    examined, but as C. apella is nowhere known to occur to the west of the Andes,

    the Tumbes monkey is most likely to be C. albifrons.

    Taxonomy._

    Cabrera fo11ows Hershkovitz (1949) in limiting the number of races

    occu rring in the Peruvian Amazon region lo three. Of those, he gives C. a. uni-

    color

    Spix a range covering the basins of the Rio Ucayali and the Rio Huallaga;

    and Hershkovitz cites specirnens of that form Ir orn Chicosa, Cumaria, Masisea,

    Cerro Azul, and Contamana (a11 on the Rio Ucayali) and fram Puerto Victoria

    (on the Rio Pachitea) and Tingo Maria. C. a.

    cuscinus

    Thomas (type locality

    Callanga, Rio Pirupini, Oept. of Cuzco) is g iven the range of the valleys of the

    Rio Urubamba and the Rio Alto Madre de Dios, to which form Hershkovitz refers

    a specimen from Uviní, at 1,500 m. on the Rio Urubamba.

    16

    C.

    a. yuracus

    Hershkovitz is said to occur between the Rio Maranon and the

    Rio Napa, Hershkovi tz mentioning specimens fr om a number of localities on the

    latter river. If C. albifrons does occur in the coostal region, it is most likely to

    be in the form C.

    a. aequatorialis

    J. A. Allen, which is known from the cocst of

    Ecuador a good deal further north.

    Status.- It is dífficult to assess the status of C.

    albilrons ,

    as it cannot always be

    distinguished from C.

    apella

    in the field. It is generally reported to be less com-

    mon than the latter species, however; and the very much sma11er numbers of it

    that are exported may be a true reflection of the relative abundance of the two

    species-at least in the ar eas where capture operations are carried out.

    Genus

    Saimiri

    Voigt - Squirrel Monkeys

    Local Names.- Fraile, Hueso, Sillere (Campo).

    Distribution.-

    Monkeys of this genus have been recorded from a11 parts of the low

    selva zone of the Amazon region, from the north to the south of the country.

    They also occur in the lower parts of the high selva zone, up to heights usua11y

    rather less than those attained by

    Cebus apella.

    In some localities, however,

    individual bands are said to move up to nearly 2,000 m. when certain fruits are

    ripening.

    Taxonomy.-

    Cabrera recognizes only one species, Saimiri

    sciureus

    (Lírm.). as

    occurring in the whole of South America, of which he regards the form in north-

    ern Peru to be S.

    c. macrodon

    Elliott, with S.

    c. nigriceps

    Thomas (type loca lit y

    Cosnipata, Oept. of Cuzco) replacing it in the basins of the Ucayali and Uru-

    bamba in the south. Osman Hilllimits the range of S. sciureus to the area north

    of the Amazon and Rio Maranon, and recognizes a separate specíes, S.

    usted

    l.

    Geoffroy, as occurring to the south. He sta les , however, tha t that species is

    of only doubtful validity; and Cabrera regards it as a synonym of S.

    c. nigriceps.

    Status.- This is undoubtedly the most common species of monkey in Peru. It is

    gregarious and somewhat nomadic in habits, and is still to be found in bands of

    up to 30 or 40 individuals in most parts of its range. It has survived in many

    of the less densely populated areas of settlement, where ít occasionally does

    damage to crops, being particular ly destructive in cacao plantations. Over

    25,000 immature animals are exported annua11y for medical research purposes,

    and many more thousands must die in the course of capture and transportation.

    The species cannot, however, be regarded as immediately endangered. Saimiri

    sciureus

    is present in the Manu Nat iona l Park.

    Genus A te/es Geo ff ro y - Spider Monkeys

    The two species of this genus that occur in Peru are treated separately below.

    Ate/es

    be zebuth

    Geoffroy - Long-hai red or White-bel lied Spider Monkey

    Local Name.- Maquisapa.

    Distribut ion.- This species is confined to the northern part of the Amazon region,

    where it occurs in both the low selva zone and the high selva zone, up to cltí-

    17

  • 8/18/2019 Notes on the distribution and status of some Peruvian mammals, 1968

    13/49

    tudes of at least 1,000 m. It is known by specimens from the Río Napa and the

    Rio Tigre, the Amazon at Iquitos, the Rio Maranon and the Rio Samiria, and

    Irom Sarayacu on the lower Río Ucayali, as well as from several localities in

    the Moyobamba and Lamas Provinces of the Deportrnent of San Martin. Its

    southern limit is dífficult to determine, but

    ít

    reaches to at least

    7 .00 '

    S. in the

    va11ey of the Rio Ucayali, and is rather dubiously reported to occur even further

    upstream.

    T axonomy.- Ate/es bel zebuib ís known only in the nominate form within Peruvian

    limits.

    Status.- Members of the genus

    Ate/es,

    together with

    Lagotbrix,

    are the most highly

    prized of a11 monkeys for human food. As a result, this species has suffered

    severely from huntinq throughout its range. It has disappeared from many ports

    of

    it,

    and ís said to be on the decline everywhere else. Ate/es belzebuib is

    present in the proposed Hio Samiria and Hio Pacaya Reserve.

    Ate es paniscus (Linn.) - Black Spider ~nkey

    Local Names.- Maquisapa, Tuero (Campa).

    Distribut ion.- This species is found throughout the low selva zone and the lower

    levels of the high selva zone, in the southern part of the Amazon region. It ís

    known by spec imens or reliable reports from Chicosa

    ( l0 .50 '

    S.) and Cerro Azul

    (7 .20 '

    S.) on the Rio Ucayali, and from the Rio Curanja (a11 in the Department of

    Loreto), and from the Provinces of Mariscal Caceres (San Martin); Tingo Maria

    and Pachitea (Huanuco); Oxapampa (Paseo); Jauja (Ayacucho); La Convencion,

    Calca, Paucartambo, and Quispicanchis (Cuzco); Carobaya and Sandia (Puno):

    and Manu and Tambopata (Madre de Dios). The species occurs at greater height

    than any other monkey except

    Lagotbrix

    and is regularly reported at altitudes of

    from 1 ,70 0 to 1 ,80 0 m.

    1 have been unable to determine where and to what extent A. paniscus over-

    laps with A.

    be/zebuth,

    but that there ís an overlap (or was one at least in íor-

    mer times) is indicated by Osman Hi11's reference to a specimen of A. paniscus

    collected near the confluence of the Río Yavari with the Amazon, in 1848; to

    Bartlett fmdínq that species  In forests bordering the Río Ucayali and in the

    lower d istricts bordering the Peruvian Amczon in 187 1 ; and to Cabrera (1 91 7)

    listing A.

    paniscus

    from Peruate on the Rio Maranon. Nowadays the two species

    are said to cccur in close proximity to one another in the neighborhood of Con-

    tamana, on the Bío Ucayali, but 1 have not been able to check that information.

    Tax onomy.- Ate/es paniscus ís represented by the black-faced race A. p. chamek

    (Humboldt) throughout.

    Status.- Thís species has probably fared better over-a11 than the preceding one,

    S10ce considerable ports of its range are remote from settlement and inccces-

    s ible to waterborne hunters. Nevertheless, it has suffered severely wherever

    ít

    habs come into contact with civilization, and

    it

    has disappeared from a great

    num er of its former haunts.

    Genus Lagothrix Geoffroy - Woolly Monkeys

    The three species of this genus that occur in Peru are treated separately below.

    Lagothrix cana

    (Geoffroy) - SmokeyWoolly Monkey

    Local Names.- Choro, Uche-to (Campa), Zuruu (Chcyhui tc), Chuaa (Achucl ).

    Distribut ion.- This species is found in both the low selva zone and the lower

    levels of the high selva zone in almost a11 parts of the Amazon region. In the

    Department of Loreto it is known by specimens from the Ríos Napo, Nanay,

    Maranon, and Samiria, and from Cumeria and Cerro Azul on the Rio Ucayali;

    and it is almost certainly this species of

    Lagotbrix

    that was encountered by

    Dr. A. L. Gardner on the Rio Curanja. Elsewhere it is known by specimens or

    reliable reports from the Provinces of Moyobamba (San Martin); Tingo Maria and

    Pachi tea (Huanuco) ; Oxapampa (Pesco); Tarma ( Junín) : Jau ja (Avocucho): Calca ,

    Paucartambo, and Quispicanchis (Cuzco); Sandia (Puno): and Manu and Tambo-

    pata (Madre de Dios). It occurs at higher altitudes than any other monkey, and

    ís reporte d to be found at 1 ,800 m. in many localit ies.

    Taxonomy .- Cabrero considers the form in the north to be L. c. poeppigii Schinz

    (type locality Maynas, on the Rio Maranon), with a range extending as far south

    as the lower Río Ucayali and the Rio Yavari. According to the same authority,

    L. c.

    oliuacea

    (Spix) replaces L. c.

    poeppigii

    in the middle and upper parts of

    the Ucayali basin and in the basin of the Urubamba, and is presumobly also the

    form further south. Osman Hill considers that the nominate race may extend

    into Peru along the north bank of the Amazon as far west as the Rio Napo.

    Status .-

    Woo11y monkeys are much persecuted, as their f1esh is highly e steemed,

    and they command the highest price of a11 in the live monkey trode. They are

    not

    dífficult

    to hunt; and because they are found only in sma11 family parties,

    local popu lations are eos ily exterminated. This specíes has disappeared from

    the neighborhood of a11 settlement and from the banks of the larger rivers, and

    it is probably on the decline everywhere except in the remoter and higher parts

    o f i ts ronge which are inaccessible to waterborne hunters.

    Lagotbrix cana

    is present in the Manu National Park.

    Tambo,

    80

    kms. east of Chachapoyas, by R. W. Hendee in

    1926.

    It is so far

    known only from a sma11 areo on the border of the Departments of Amazonas

    and San Martin in that region, where it occurs at altitudes of from 1 ,700 m. to

    3 ,000 m.

    Taxonomy.-Callimico goeldii

    (Thomas) is the only species in

    this genus. This little-known and apparen tly r ore monkey, wh ich resembles the

    marmos

    ets

    in many respects, has been recorded from only a few isolated local-

    ities, principally in western Brazil. The only record of its occurrence in Peru

    that 1 am aware of is the two specimens collected by R. W. Hendee at Cerra

    Azul (near Contamana, on the Rio Ucayali) in 192 8. Osman Hi ll, however, in

    his distribution map of the species, shows it as also occurring along the  Serra

    Contamana  on the Peruvian-Brazilian border írorn about 7.00 ' S. to 9.00' S.,

    although he quotes no records from that oreo. He also states that a live speci-

    men exhibited in the New York Zoological Pork was believed to have been

    al ic;inally acquired in Iquitos.

    Status.- 1 hcve been unable to discover anything of the status or the occurrence

    of this species, but it may be that other live specimens occasionally reach

    dealers in lquitos and ore exported as  pichicos  -the portmanteau word used

    to cover 011marmosets.

    CALLlTHRICIDAE

    Genus

    Cebuella

    Gray - Pigmy Marmosets

    Local Name.- Leoncito.

    Distribution.- The known range of the single species of this genus is the Amazon

    valley from approximately

    64.00 '

    W. westward into southern Ecuador and north-

    ern Peru. It is well known along the Peruvian Amazon and the lower reaches

    of the Rio Napa, and specimens are known from Iquito s and Ch imbo te (250 kms.

    downstream from the junction of the Rio Napo with the Amazon). 1 have been

    unable to determine either its western or its southern limit, but a specimen is

    known from Santa Cruz, on the Rio Huallaga at

    75 .50 '

    W.,

    5.20 '

    S. A specimen

    is also known from the upper basin of the Rio Pastaza, some 15 0 kms. ocross

    the border into Ecuador.

    Taxonomy.-Cebuella pygmaea (Spíx) is the species, of which only the nominate

    rece is found in Peru.

    Status ..- Judged solely by the number of animals kept as pets, or available on the

    Iquitos morket, this species does not seem to be at 011 rare within its limited

    range. Altogether

    972

    Genus

    Leontocebus

    Wagner - Tamarins or Long-tusked Mormose ts

    Local Names.- Píchíco, Titi.

    Distribution and Taxonorny.- The members of this genus are confmed to the low

    selva zone of the Amazon region, in almost every part of which one or more

    species is to be found. With the exception of Leontocebus imperator with its

    long white mustaches (and presumably the pied L. bicolori, they are difficult or

    impossible to distinguish in the field, Of the 23 species recognized by Cabrera,

    the following

    12

    have been recorded from Peru.

    Leantocebus

    bic r

    (Spix) - Pied Tamarin

    According to Cabrera, this species is found within Peruvian limits only on the

    north bank of the Amazon, from the Colombian border west to the Rio Napa.

    Osman Hí ll's (1 957) distribution map of the species shows it as not reaching

    Peru at

    0 1 1 ,

    but in his text he cites 1. Geoffray

    (185 1 )

    as the authority for its

    occurrence at Pebas (160 kms. downstream from Iquítos).

    The type loca lit y of thís species is Tarapoto, on the Rio Ncpo, near the junction of

    Leantocebus lagonotus (Espada) - Golden-mantled Tamarin

    The type locality of this rather doubtful species is Destacamento, near the conflu-

    ence of the Rio Napo with the Amazon. Cabrera considers this form to ha ve

    clase offinítíes to L.

    illigeri

    bu t to be r ecogn izable as a separate species, to

    whích he gives the range of  the north of Peru and Ecuador . Osman Hill con-

    siders it to be no more than a race of L. illigeri and gives the distribution of

    that roce as  the Rio Napa . As he includes Matschie's L.

    bluntschlii

    i n that

    race, however , its range must be extended to include  the Rio Samirio, an afflu-

    ent of the Rio Maranon  (presumably a misprint for Rio Somir i c), from where

    L. bluntschlii was described.

    Leontocebus

    illigeri

    (Pucheran) - Red-mantled T amarin

    Cabrera gives the range of this species as northeast Peru, east Ecuador, and the

    extreme southeast of Colombia, in the basins of the upper Solimoes (i.e., Ama-

    zon) and the Río Maranon. As he regard s Thomas's L.

    mounseyi

    as inseparable

    fram C. illigeri, however, he must consider the Rio Pacaya (en affluent of the

    lower Ucayali, from where L.

    mounseyi

    was described) to lie within that area.

    Osman Hill gives the range of L. illigeri as  the Colombian bank of the Rio

    Solimoes ( i.e., Amazon)-exact range unknown , but then goes on to cite local-

    ities to the south of the Amazon from which it has been recorded, includinq the

    Rio Pacaya type locality. of L. mounseyi , which he also regards as inseparable

    fram L. illigeri. In his distribution map he shows the species as occupying an

    enormous range , ínc ludínq the whole of the basins of the Rios Ucayali and Hua-

    llaga to almost 1 1 .0 0 ' S., as well as those of the Rios Napo, Tigre, Pastaza,

    and Maranon in the north.

    Leontocebus pi eatus (1 . G eo ff ro y an d D ev il le) - R ed -c ap ped T am ar in

    The main range of this species lies in western Brazil, from the Amazon south to

    the Rio Purus. Its northwestern limit extends into the extreme northeast comer

    of Peru , however , in the neighborhood of Pebas, which is its type locality.

    Leontocebus fuscicoll is

    (Spix ) -

    B r o w n-h ea de d T a m ar in

    The range of th is species is very similar to that of L. pileatus; and it, too, is known

    within Peruvian limits only fror n the neighborhood of Pebas and the Rio Yavari.

    Leontocebus labiatus (G eo ff ro y) - R ed -b el li ed W hi te-l ip pe d T am ar in

    This species is found over a large area of western Brazil, including that part con-

    tiguous to the Peruvian border from the Amazon in the north to the Rio Purus at

    about 11.00' S. Both Cabrera and Osman Hi11 state that it extends into eastern

    Peru, but neither gives any indication of to what extent it does so or in what

    localities. Osman Hi11's distribution map, however, shows

    it

    as occupying the

    whole length of the eastern Ucayali basin, but at no point extending as far west

    as the river itself.

    Leon to c ebu s mystax ( Sp ix ) - M o us t ac h ed T a m o r in

    The range of this species is apparently similar to that of L. labiatus, but it extends

    further to the north and west. Cabrera states that it ís to be found with in Peru-

    vian limits f rom the Brazilian border westward to at least the Rios Napo and

    Ucayali; while Osman Hi11's distribution map shows the species as occupying

    the lower basins of the Ríos Napo and Tigre in the north, and everywhere east

    of the Hua11aga-Ucayali watershed, to about 9.00' S., in the south.

    Leontocebus dev i l le i (1. Geo f f r o y ) - De v i l le s T am ar in

    This species is apparently confmed to Peru, where Cabrera gives it the range of

    the basins of the Ríos Ucayali and Hua11aga. It is very similar to L. nigricollis,

    with whích it ís sympatric in some areas, and of which Osman Hi11and Hersh-

    kovitz regard it to be a mere color phase. It was described from Sarayacu, at

    6.40' S. on the Rio Ucayali; and specimens of it are known from Yurucyacu

    (Moyobamba Province, Oept. of San Martin) and Irorn Aguas Calientes (near the

    junction of the Rios Pachitea and Uccyclí). as well as Irom the type locality.

    Leon to c ebu s nigricollis (Sp i x ) - B la c k-an d-R ed T a mar in

    Cabrera gives the range of thís species as  western Brazil, along the Rio Soli-

    moes, and eastern Peru, in the bcsín of the Río Ucayali . Osman Hi11 confines

    its range to Peru, and in his distribution map further restricts it to the area be-

    tween the left bank of the Rio Ucayali and the Ucayali-Hua11aga watershed, and

    to a contiguous s tr ip a long the north bank of the Rios Maranon and Amazon from

    the Río Tigre to the Rio Putumayo. Osman Hi11 refers to specimens írom Pebas

    and Iquitos; and the catalogue of the Fíeld Museum of Natural History, Chicago,

    lists others from Pachitea, Yarinacocha, Ganzo Azul, and Pucallpa, a11 on the

    Rio Ucayali, and f rom the Rio Hua11aga.

    Leontocebus weddel i (Devi l le) - W ed d el l s T am a ri n

    Although this f orm closely r esembles

    L. nigricollis,

    most authorities regard it as a

    separa te species. It ranges thraugh western Brazil, in the basin of the upper

    Ríos Purus and Acre, northern Bolivia, and the southern part of the Peruvian

    Amazon region. It has been recorded from greater altitudes than most other

    species, a specimen having been taken at 1.370 m. on the Rio San Miguel, in

    the Calca Province of the Oepartment of Cuzco. Other specimens are known

    Irorn Chicosa (on the Rio Ucayali, at 10.20' S.). the Rio Cosireni (La Conven-

    cion Province, Oept. of Cuzco), Marcapata (Quispicanchis Prov ince, Dept. of

    Puno), and San Ignacio (Sandia Province, Oept. of Puno).

    Leontocebus imperator (G oeld i) - Em pero r T am ar in

    Cabrera gives the range of this distinctive species as wes te rn Brazi l, in the basins

    of the upper Rio Purus and its tributaries. It is now known to extend further

    west, however, into the southern part of the Peruvian Amazon reqion, where

    specimens are known from the Rio Curanja, in the Oepartment of Loreto, and

    from the Rio Manu, in the Manu Province of the Oepartment of Madre de Dios.

    Sta tus . - Large numbers of tamarins are captured in the northern part of the De-

    partment of Loreto for export alive, nearly 2,000 being dispatched in 1964.

    Because of their high mortality rate in captivity, many thouscnds more must die

    in the process of capture or dur ing t ransportation to Iquitos. It is not known if

    this practice threatens any of the less common species, but most of the animals

    1 have seen awaiting expor t appeared to be

    L. nigricollis

    or

    L. illigeri .

    Torne-

    rins are rarely molested by man in other ways; and, in the southern part of the

    country at least, they are frequently to be seen on the banks of rivers in parties

    cl~~~. .

    L. imperator is known to occur in the Manu National Park, and two other spe-

    cies-of which one is presumably

    L. weddelli-are

    also reported to occur.

    L. lagonotus and L. illigeri have both been recorded from the proposed Rio

    Samiria and Rio Pacaya Reserve, and

    L. devillei

    and

    L. nigricollis

    are probably

    to be found there as well.
