Introduction

The orb-weaving spider family Nephilidae Simon containsthe (sub)tropical genera

Nephila

Leach, 1815,

Nephilengys

L. Koch, 1872,

Herennia

Thorell, 1877 and

Clitaetra

Simon,1889 (Kuntner 2005, this study). Perhaps the best knownnephilid features are the large ‘golden’ orb-webs of

Nephila

,reaching 1.5 m in diameter (own data), the extreme sexualsize dimorphism of

Nephila

and

Nephilengys

in which themales are a fraction of the size of the females (Coddington

et al

. 1997; Hormiga

et al

. 1995, 2000; Harvey

et al

. in press;Kuntner 2005), and the bizarre sexual biology of

Nephila

and

Herennia

, where broken-off male sperm transferring organsare commonly found stuck in female genital openings (Kuntner2005). In contrast, little is known about

Clitaetra

diversityand less about its biology.

Nephilinae was first recognized by Simon (1894), but itsfamilial placement within Araneoidea has changed repeatedly(see also Kuntner 2002, 2005; Kuntner & Hormiga 2002).Simon’s (1894) argiopid subfamily Nephilinae consisted ofthe genera

Singotypa

Simon, 1894,

Phonognatha

Simon, 1894;

Deliochus

Simon, 1894,

Nephila

(

Nephilengys

included),

Clita-etra

, and

Herennia

. Later,

Singafrotypa

Benoit, 1962 and

Perilla

Thorell, 1895 were included in nephilines, and

Singotypa

wassynonymized (Dondale 1966) with

Phonognatha.

For most ofthe ‘precladistic’ 20th century Nephilinae remained placedwithin Araneidae. Levi (1980) placed

Nephila

in the araneidsubfamily Metinae. Later, Levi (1986: 99) considered

Nephila

and

Nephilengys

to ‘probably’ belong in Tetragnathidae andLevi & von Eickstedt (1989) retained the whole subfamilyNephilinae in Tetragnathidae.

The first cladistic analysis containing nephiline genera(Coddington 1990), with 32 orbicularian taxa scored for87 morphological and behavioural characters, recovered amonophyletic clade (

Nephila

and

Nephilengys

) as sister totetragnathid genera

.

L. Koch, 1836,

Leucauge

White,1841,

Tetragnatha

Latreille, 1804 and

Glenognatha

Simon, 1887.The nephiline placement of

Phonognatha

and the monophylyof Nephilinae and Tetragnathidae were further tested byHormiga

et al

. (1995) with a denser taxonomic sample. Theresults of the latter study corroborated Coddington’s (1990)hypothesis of Nephilinae as the sister group of the remainingtetragnathid lineages and hypothesized the relationships ofnephiline genera: (

Phonognatha

(

Clitaetra

(

Nephila

(

Herennia

+

Nephilengys

)))). The study of Hormiga

et al

. (1995), based onmorphological and behavioural data, recovered the mono-phyly of Nephilinae and of Tetragnathidae, a result later cor-roborated by Griswold

et al

. (1998) within a broad taxonomicsample of araneoids. Kuntner & Hormiga (2002) and Kunt-ner (2002) revised the ‘nephiline’ genera

Singafrotypa

and

Perilla

, and placed them phylogenetically in Araneinae(Araneidae). Recent studies (Pan

et al

. 2004; Wunderlich 2004)including a preliminary finding from this research (Kuntner2003) have hypothesized nephilines as sister to Araneidaerather than Tetragnathidae. However, no prior work hasemphasized

Deliochus

and no nephiline phylogeny exists atthe species level, making evolutionary interpretations of theavailable biological data difficult or impossible.

Taxonomic history

Simon (1889) erected the monotypic genus

Clitaetra

(thenin Epeiridae) and described

C. episinoides

Simon, 1889 fromMayotte. In his encyclopedic treatise of world spiders, Simon(1894) redescribed the genus (original misspelling

Clytaetra

)with a single drawing of the ocular area of

C. episinoides

(typespecies) and described a new species,

Clitaetra perroti

fromthe eastern Madagascar coast. Simon (1894) placed

Clitaetra

in Clitaetreae within Nephilinae, family Argiopidae. In 1903,Simon described the third species,

Clytaetra

[sic]

thisbe

fromSri Lanka, which remains the only

Clitaetra

species foundoutside Africa with Madagascar. Simon (1907) then described

C. clathrata

Simon, 1907 from Guinea Bissau (Guinee portug.),and diagnosed all four species. Benoit (1962) redescribed

C. clathrata

and described a new species,

Clitaetra simoni

from Zaire (Sankuru, D.R. Congo). Schmidt & Jocqué (1986)described and illustrated the male of

C. episinoides

from theComoro Islands. Hormiga

et al

. (1995: 330) illustrated the malepalps of

C. perroti

(misidentified as

C. episinoides

) (theirfig. 9D,E) and

C. clathrata

(as

Clitaetra

sp.) (their fig. 9A–C)and provided spinneret images of

C. irenae

sp. nov. (as

Clita-etra

sp.; their fig. 15A–D).Simon (1889, 1894, 1903, 1907) provided brief descrip-

tions in Latin, without illustrations, based exclusively on

scarce female material and did not designate types. Un-surprisingly, most species have remained unstudied and theiridentification is difficult. In this study,

Clitaetra

species areredescribed, diagnosed and illustrated using type specimens,with first descriptions of the males of

C. perroti

and

C. clath-rata

. A new species,

C. irenae

sp. nov. from southern Africa isdescribed with extensive information on its biology.

Scope

Clitaetra

specimens are rare in collections and

Clitaetra

naturalhistory has never been described. A photograph of

Clitaetra

in Preston-Mafham (1991 : 117) (=

C. irenae

sp. nov.) suggestedarboricolous habits with a web against tree trunks (confirmedby personal communications of Astri Leroy (on

C. irenae

sp.nov.) and of Rudy Jocqué (on

C. episinoides

)), similar to

Herennia

(Robinson & Lubin 1979; Hormiga

et al

. 1995;Kuntner 2005). Limited behaviour entries coded for

Clitaetra

in a phylogenetic analysis of tetragnathid genera byHormiga

et al

. (1995) demonstrate the need for new materialand behavioural data. I focused on the behaviour of thenew species from South Africa (

C. irenae

sp. nov.) during anexpedition to KwaZulu-Natal in 2001.

The present paper, the first of the nephilid taxonomic treat-ments (see also Kuntner 2005) provides detailed methodsused in nephilid taxonomy and behavioural research, andrevises the biology and the taxonomy of

Clitaetra

.

Clitaetra

morphology and behaviour are summarized for use in nephilidphylogeny and for a phylogenetic definition of the genus.A species-level phylogeny is devised for

Clitaetra

and selectednephilid and araneoid outgroups.

Clitaetra

is sister to all othernephilid genera, and thus its biology, when better known,may alter the homology and polarization of many nephilidfeatures as understood today. The phylogenetic resultssuggest that

contra

to recent cladistic studies (Coddington 1990;Hormiga

et al

. 1995; Scharff & Coddington 1997; Griswoldet al. 1998) nephilines are not tetragnathids, and thus areproposed to be treated as a family.

Materials and methodsNephilid specimen databaseThe nephilid specimen database (available for all nephilidgenera; see Kuntner 2005) was developed in BIOTA 1.6.0(Colwell 1999). At least one specimen from each examinedsample received a unique specimen code (a required field inBIOTA), which consisted of the two letter genus code (‘cl’for Clitaetra, ‘ne’ for Nephila, ‘ng’ for Nephilengys, ‘he’ forHerennia) followed by the sample number, a letter indicatinggender or stage (‘f’ for a female, ‘m’ for a male, ‘j’ for a juvenile)and the consecutive number within sample. Other specimendata included species identification and date, gender, abundance,type status, museum depository (see Museum abbreviations),and optional notes. The locality data entered in BIOTA for

each sample, if known, were: a unique locality code, localityname, district, state/province, country, elevation, latitudeand longitude and their accuracy (by convention, the word‘approx.’ in this field means the approximate coordinateswere found later through maps or gazetteers, not measuredon spot). If interpreted, the original spellings were includedin square brackets. The collection data entered in BIOTA foreach sample, if known, were: a unique collection code, collectedby (in case of one collector the first name abbreviation followedby full last name, in case of two collectors both last namesseparated by ‘&’, and in case of several collectors the last nameof the first collector followed by ‘& al.’), date collected, site(if available) and source (‘label’ indicating museum label and‘notes’ as personal notes from the field).

The nephilid specimen database, currently containing morethan 4000 entries, is available from the author. Upon publica-tion of all four nephilid revisions (Kuntner in prep., 2005, thisstudy ), the database will be made available on the internet.

Behavioural observationsAll behavioural observations were carried out in the field inthe spiders’ natural environment; voucher specimens werecollected and deposited at USNM. Observations were doneduring the day and at night, when a red filtered headlamp wasused. A microcassette recorder along with a field notebookwas used to document behaviours. Behaviours and web archi-tecture were photographed after the webs were dusted withcornstarch (Eberhard 1976; Carico 1977). Additionally,samples of crucial parts of orb webs were taken using micro-scope slides with double-sided adhesive tape on the edges.These samples were later examined under the microscope toestablish exact thread junctions and their nature.

Some behaviours are described here for the first time, andmany are further discussed in other nephilid phylogenetictreatments (Kuntner 2005; Kuntner, Hormiga and Codding-ton unpublished). Most behaviours, however, have beendescribed and discussed in the literature (for review see Eber-hard 1982) and used in recent phylogenetic analyses usingorbicularian spiders as terminals (Coddington 1986a,b,c,1990; Hormiga et al. 1995; Scharff & Coddington 1997;Griswold et al. 1998; Agnarsson 2003, 2004, 2005). Thenomenclature used here attempts to follow the publishedaccounts (see Abbreviations).

Morphological examinationMost morphological observations and illustrations of exter-nal structures were made using a Leica MZ APO dissectingmicroscope with a camera lucida. For internal palpal andepigynal anatomy a compound microscope Leica DMRMwith a camera lucida was used. Microscope images were takenusing a Nikon DXM 1200 digital camera, and assembledwith Syncroscopy Automontage software. Digital SEM photo-

graphs were taken on a Leo 1430VP scanning electronmicroscope at the Department of Biological Sciences,George Washington University. For SEM preparation, speci-mens were cleaned ultrasonically for 1 min, transferred to100% ethanol overnight, dissected and submitted to criticalpoint drying, mounted on rivets using glue and copper wire,then sputter-coated.

Female genitalia and male palps were excised using scalpelsand needles. Male palpal anatomy (trajectory of the ducts)and internal female genitalic structure were examined byclearing the organs in methyl salicylate (Holm 1979), mount-ing them on a temporary slide (Coddington 1983) andillustrated under compound microscope. In spiders withlarge and heavily sclerotized internal genitalia (Nephila,Nephilengys) this technique works poorly. Thus, in order todecipher the trajectory of the copulatory ducts, the epigynawere exposed to concentrated KOH to completely digest anysoft tissues. Cleared genitalia were illustrated under a dissect-ing microscope and sometimes further dissected to exposethe details. With this technique it is often necessary to inter-pret the relationships of the positions where the copulatoryand fertilization ducts attach to the spermatheca lumen. Malepalps were expanded by exposing them to concentrated KOHfor up to an hour, followed by immersion in distilled water,and the process repeated as needed. Nephilid palps rarelyexpand fully, probably due to relatively small haematodochae,and the extent and the close association between the long embolusand the grooved embolic conductor. Often, the embolusneeded to be pulled out of the embolic conductor, riskingbreakage of structures. To fully understand the sclerite asso-ciations, more destructive dissections have to be made, oftenatomizing the palps into separate sclerites and their parts.

All measurements are in millimeters and were made usinga micrometer eyepiece. Prosoma and opisthosoma length andheight were measured in lateral view, the width in dorsalview; all measured at widest points (prosoma height meas-ured at head region). Eye widths are maximum diameters ofthe eye lens and eye separations were measured betweenlenses. Leg segments were measured in detached legs. Onlyjoints distal from the trochanter were measured, as thedetached leg breaks between the trochanter and the femur.Maximum lengths of femur, patella, tibia, metatarsus andtarsus are reported; the total of these is the approximated totalleg length [if all leg joints were measured at the maximumjoint leg, the sum would overestimate the total leg lengthbecause joints partly overlap at junctions].

ImagingLarge nephilid females commonly exhibit diagnostic somaticmorphology and colour patterns. Less conspicuous, notablyin Nephila and Clitaetra, is the epigynal morphology, oftencovered with the tissue posterior to the epigynal plate. Thus,

female habitus illustrations in addition to the epigynum areprovided for all species, with variation if applicable. In con-trast to the large females, the male somatic morphology is fairlyuniform within genera. Their (unexpanded) palps, however,are diagnostic, and thus illustrated for all species. Ectal viewsare especially useful and should suffice for species identifica-tion (provided the examined palp is viewed from exactly thesame angle, for which it is best detached from the spider).

Pencil illustrations via camera lucida were kept on acid-free archival paper. Simple line illustrations were inked onVellum film; shaded illustrations were inked on fine grainedcoquille board and further rendered with black, soft Prisma-color pencils. All nondigital artwork (photographic slidesincluded) was scanned for digital manipulation in AdobePhotoshop 7.0, where digital microscope and SEM imageswere further manipulated. All image plates were assembledand labelled in Adobe Illustrator 10.

Phylogenetic analysisAll known Clitaetra species represented the ingroup. Nephili-nae sensu Hormiga et al. (1995) included the genera Nephila,Nephilengys, Herennia, Clitaetra and Phonognatha, and weresister to other tetragnathids. I used the type species ofall nephiline genera in the analysis: Phonognatha graeffei(Keyserling, 1865), Herennia multipuncta Doleschall, 1859,Nephilengys malabarensis (Walckenaer, 1842) and Nephilapilipes (Fabricius, 1793). I included the second species ofNephilengys (N. cruentata (Fabricius, 1775)) and Herennia(H. papuana Thorell, 1881) to test for the generic monophyly.In the large pantropical genus Nephila more exemplars wereused. Harvey et al. (in press.) revised the five Australasianspecies, of which four are represented in this analysis: N. pilipes,N. antipodiana (Walckenaer, 1842), N. plumipes (Latreille,1804) and N. edulis (Labillardière, 1799). Additional speciesfrom the Americas (N. clavipes (Linnaeus, 1767)), Africa(N. fenestrata Thorell, 1859), and Asia (N. clavata L. Koch,1878) were included. About six Australasian species ofDeliochus are known (two described). The particular speciesincluded here, for which I have behavioural data, is un-described. The non-nephiline outgroup taxa are a subset ofthose in Kuntner, Hormiga and Coddington (unpublished;see their specimen information): Deinopis MacLeay, 1839 andUloborus Latreille, 1806 are the nonaraneoid outgroups. Ara-neids are represented by Araneus Clerck, 1757 and two ArgiopeAudouin, 1826 species with remarkably different somaticand genitalic morphology. Tetragnathids are represented byTetragnatha, Meta and Leucauge, and the reduced piriformclade taxa are as in Hormiga et al. (1995): Linyphia Latreille,1804 (Linyphiidae), Pimoa Chamberlin & Ivie, 1943 (Pimoi-dae), Steatoda Sundevall, 1833 (Theridiidae), NesticusThorell, 1869 (Nesticidae), and Epeirotypus O. P.-Cambridge,1894 (Theridiosomatidae).

Appendix 1 lists the characters and character states used inthe analysis. The characters and their homologies will be dis-cussed in more detail elsewhere (Kuntner 2005; Kuntner,Hormiga and Coddington unpublished). The phylogeneticmatrix (Appendix 2) of 197 characters scored for 32 taxa inNONA format (ss) is available from the author and will besubmitted to TreeBASE (www.treebase.org).

For the cladistic analysis I used NONA version 2.0 (Golo-boff 1993) under both amb – (default) and amb = (allows formore ambiguous support) and with parameters hold 1000(keeps 1000 trees during searches), mult*500 (random taxonaddition), max* (performs the tree bisection-reconnection(TBR)), and sswap (branch swapping algorithm). I usedWinclada 1.00.08 (Nixon 2002) to display and manipulatetrees and matrices for NONA. Successive character weight-ing (Farris 1969) analysis was performed in NONA with thecommand run swt.run hold10000 hold/100 mult*100(using the macro swt.run). The bootstrap values (Felsenstein1985) were calculated in Winclada using default settings (100replications, mult*10). Bremer support or decay index values(Bremer 1988, 1994) were calculated in NONA using thecommand bs10 and hold 100000.

All trees are output from Winclada and their formatdoes not imply nonmonophyly of the group Deinopoidearepresented here by the two primary outgroups, Deinopis +Uloborus.

ClassificationI use a compromise approach between the (classical) zoo-logical nomenclature (ICZN 1999) and phylogenetic nomen-clature (Cantino & de Queiroz 2004). A review of the debatewith a rationale for such combined classification is in prepa-ration (see also Kuntner 2005). Clade names in this study areconsistent with zoological ranks up to the family level, but areprecisely circumscribed following the PhyloCode articles 7,9–11 (Cantino & de Queiroz 2004). Phylogenetic definitions(PC Article 9, Note 9.4.1) used here are node-based where‘clade (A and B)’ means the least inclusive clade containingA and B. Due to ambiguous character support (Fig. 28),apomorphy-based clade definitions or combined definitionsare not used. Because the PhyloCode has not yet taken effectand the registration database has not yet been implemented,the names proposed here are not registered (Article 8).

ResultsBiologyI studied Clitaetra irenae sp. nov. in South Africa at FaniesIsland, Sodwana Bay, Tembe Elephant Park, and PhindaResource Reserve (photographs available on request). Thespecies is abundant in sand forests of northern lowlandKwaZulu-Natal. The spiders typically spin their orb webs ontree trunks, but one female was taken from a web built on arock outcrop at Phinda, and spiders were commonly collectedfrom wooden walls at localities around St. Lucia Estuary. Thewebs (photographs available on request) could be describedas ladder-webs, as they are built more or less vertically, areelongated with parallel vertical sides and their ‘spirals’ runparallel. The webs are typically built within tree trunkdepressions such that the clearance between the web and thetree is greatest at the hub (typically 2–4 cm in female webs).The hub of the orb is reinforced with a fine silk mesh, whichmay be homologous to the ‘hub-cup’ of Herennia and to theretreat of Nephilengys. The spider rests at the hub, typicallywith prey remains suspended above the hub.

The webs of adult females are eccentric, the lower portionbeing larger than the upper (the ratio top frame to hub/topto bottom frames ranged from 0.21 in a female at Phinda to0.31 in female at Makakatana); only some juvenile webs areeccentric. Females, juveniles and even adult males were seenin prey-ready position head-down at the hub, with legs I and

II partially flexed. I collected three males from their ownminiature orb webs (photographs available on request), and asample from Phinda contains no sticky silk, suggesting theweb was made after the last moult. Adult males were com-monly found on webs of either adult or juvenile females anda male was observed guarding a female, which had alreadydeposited her eggs, with the egg-sacs suspended in the planeof the web above the hub.

Clitaetra irenae builds webs at night and in the early morn-ing hours, sometimes only partially renewing the old web(typically, the hub and an orb sector are retained and mayonly be reinforced). Most specimens observed at FaniesIsland (n = 16) did not build between 05:00 and 01:00 exceptwhen fixing partially damaged webs, but one female at Tembewas doing frame behaviour at 20:30. Typically, web-buildingbehaviour started at around 02:00 and was terminated by05:00.

The following summarizes web architecture and buildingbehaviour (for character descriptions see Kuntner 2005):sticky spiral localization is done with outer fourth leg; hubloop-NSS transition is gradual; hub bite-out is absent; hub isalways closed; radii are attached twice on the frame (exceptlate radii, attached singly), and once on the hub; radii are notcut-and-reeled; nonsticky spiral (NSS) persists in finishedweb [NB: This behaviour was observed as it occurred (n = 2)and was confirmed from the web samples of adults and juve-niles. The persisting NSS are few and far between comparedto Nephila, and often get glued to the SS. Hence, observationsfrom the finished webs and from photographs repeatedlyfailed to establish the presence of NSS in finished webs];barrier webs are absent; NSS form is not zig-zag; silk colouris white (unlike in Nephila, where it is golden); secondary andtertiary late radii are numerous, originating on NSS; hub silkenforcement is present.

When disturbed, females and juveniles responded eitherby shaking their body or rushing to the other side of the orb.The former behaviour was common and would last up toa minute. The latter behaviour (photographs available onrequest), involves the spider smoothly and rapidly movingfrom the outer to the inner side of the orb (apparentlythrough the radii), where it rests protected by the web on oneside and the tree on the other, and showing its venter throughthe hub. This behaviour only takes a fraction of a second; asimilar sequence is known to occur in Herennia, some Nephilaand the araneid Argiope (Kuntner 2005). Females guardedtheir egg-sacs suspended in the web between the hub and theupper frame and did not abandon their protective positioneven in a highly damaged web and under stress.

Attack behaviour depended on the size of prey, but neverinvolved attack wrapping. Spiders attack small prey (flies) bybiting, followed by immediate digestion and consumption(n = 5). They attack larger prey (moth, n = 2) with a bite first,

wrap second, followed by the spider hanging the prey underthe hub, and assuming rest posture at the hub. This seems tobe a stereotypical behaviour, as it was immediately followedby re-grabbing the suspended prey and feeding on it. Asimilar behavioural sequence is also known in Nephila andNephilengys (own data).

Predatory mimetid spiders invade the webs of Clitaetra(photograph available on request). If the spiders were forcedto abandon their webs, their predators would include antsthat are abundant on tree trunks. No symbionts wereobserved in C. irenae webs. A female of Rugathodes sp.(Theridiidae) was taken from a female C. irenae web fromTembe (along with a Clitaetra male). The genus is probablynot a kleptoparasite of Clitaetra.

Web-building behaviour and natural history of all otherClitaetra species remains unstudied. A photograph ofC. episinoides from Comoro Islands (by R. Jocqué) suggeststhat the species biology may be similar to that of C. irenae inthat the species makes its orb web with a ‘hub-cup’ on treetrunks and the prey-ready position is at the hub with legs Iand II partially flexed.

PhylogenyEqually weighted analyses resulted in eight most parsimoni-ous trees (L = 531, CI = 42, RI = 70). In the strict consensusthree nodes collapse (Fig. 27A). All trees support the mono-phyly of the classical Nephilinae (Clitaetra, (Herennia,(Nephilengys, Nephila))), excluding Phonognatha (contraHormiga et al. 1995) and Deliochus. Within the ingroup, theeight trees differ in the position of Clitaetra perroti andC. episinoides, which are either a grade or a clade sister to thethree African species. The sister clade to Clitaetra are theremaining nephilids, where the monophyly of Herennia,Nephilengys and Nephila are corroborated. The sister group ofnephilids (see below) is ambiguous (Fig. 27A) and is un-resolved in the strict consensus. Possible sister clades arearaneids, the clade with tetragnathids plus araneoid sheet-web builders, or the clade with all remaining araneoids.Deliochus is sister to Phonognatha, and the clade is sister to theremaining araneoids or alternatively sister to the group withtetragnathids and reduced piriform clade. Epeirotypus(symphytognathoids) and araneoid sheet web builders (Stea-toda, Nesticus, Linyphia, Pimoa) are monophyletic and sisterto tetragnathids, corroborating Hormiga et al. (1995) andGriswold et al. (1998). Tetragnathid monophyly excludingnephilines is also corroborated.

Successive weighting analysis stabilized after the seconditeration and resulted in a single tree identical to one of thefundamental cladograms (Fig. 27B). This working hypothesisof nephilid relationships hypothesizes Clitaetra perroti andC. episinoides as monophyletic and sister to the three Africanspecies, and nephilids as sister to the clade containing all

araneoids except Araneidae. Figure 28 shows unambiguouscharacter optimization on this phylogeny, and the alternative(ACCTRAN, DELTRAN) optimizations for the clitaetrineclade.

The phylogeny based on successive weighting (Fig. 27B)and the hypothesized character support (Fig. 28) form the basisfor the newly proposed nephilid classification and taxonomy.

TaxonomyFamily Nephilidae Simon, 1894 NEW RANK

According to the phylogenetic results, the group previouslyknown as Nephilinae with the genera Clitaetra, Herennia,Nephila and Nephilengys does not group with Tetragnathidaeand thus cannot continue to be catalogued there. Nephilidmonophyly, also corroborated by Kuntner (2005), and itsposition within Araneoidea will be retested within a largertaxonomic sample (Kuntner, Hormiga and Coddingtonunpublished) and its phylogenetic definition reassessed.

Phylogenetic definition. The family Nephilidae Simon, 1894is defined as the least inclusive clade, containing Clitaetra,Herennia, Nephila and Nephilengys.

Subfamily Clitaetrinae Simon, 1894

Monophyly. Four unambiguous synapomorphies are hypoth-esized for the clade Clitaetrinae (Fig. 28), identical incomposition to the genus Clitaetra (see Discussion): PLElarger than PME (15/1), sternal tubercle I absent (25/0), manyventromedian sclerotizations (58/1), and caudal copulatoryopening position (89/0). Further, ambiguous support(ACCTRAN optimization, Fig. 28) comes from: sternaltubercle III absent (27/0), female chillum absent (31/0), scle-rotized cymbial ectal margin (121/0), ventral tegular apoph-ysis (137/1), absence of embolic conductor membrane (145/0), finger-like embolic conductor shape (146/1), denticulatedembolus base (158/1), and side change on web (194/1).

Phylogenetic definition. The subfamily Clitaetrinae Simon,1894 and the genus Clitaetra Simon, 1889 are defined as theleast inclusive clade containing C. episinoides Simon, 1889(the type species of Clitaetra) and C. thisbe Simon, 1903. SeeDiscussion.

Clytaetra: Simon 1894: 756; Roewer 1942: 925; Brignoli1983: 241. [Subsequent misspellings]Etymology. Unknown. The name is feminine in gender(Bonnet 1956: 1100).Monophyly. See Clitaetrinae, Figs 27, 28 and Discussion.Phylogenetic definition. Defined as Clitaetrinae, above (seeDiscussion).Diagnosis. Clitaetra differs from all non-nephilid spiders bythe striated cheliceral boss in both sexes (Figs 9C,D, 14A,Band 16A,B), and from all other nephilid genera by the pres-ence of a ventral tegular apophysis (Fig. 18A–D: VTA) andthe eye arrangement (Figs 1A, 3B, 5B, 6A, 7A, 9A, 12A, 16A,19A, 20A–C, 21A,B, 23A,B and 25A): lateral eyes widelyseparated, and posterior lateral eyes larger than the posteriormedians. It can further be distinguished from Nephila andNephilengys by the narrow cephalic region, dorsoventrallyflattened female abdomen and the sternum lacking sternalhumps, and from Herennia by the absence of abdominalsigillae, the absence of abdominal lobes, and by the smoothembolus without a hook.Note on conductor homology. Like other nephilids, Clitaetramales possess an extensive sclerite functioning as the conduc-tor, which entirely wraps the embolus (EC in Fig. 13).Schmidt & Jocqué (1986) referred to it simply as the embo-lus, but Hormiga et al. (1995) homologized it with the arane-oid conductor. While its homology with the conductor is stillone of the two alternative hypotheses, the sclerite is actuallywithin the embolic division (Kuntner 2005), and could betterbe described as the embolic conductor. This implies non-homology with the araneoid conductor, which is absent inClitaetra. The sclerite nomenclature here follows the term‘embolic conductor’ (EC).Description. Female (Figs 12, 14 and 15): Prosoma lengthfrom 1.6 to 3.5; total length from 3.5 to 9.9. Prosoma piri-form with narrow cephalic region. All eyes lack tapetum.Cheliceral boss with 50–100 striae (c. 300 in C. simoni), che-licerae with three prolateral and three or four retrolateralteeth and denticulated furrow (Fig. 3D). Sternum with threepaired groups of slit sensilla visible under dissecting micro-scope (Fig. 12C,D), numbers in each group varies from oneto five. Irregular patches of white pigment present onsternum.

Opisthosoma oval topentagonal with three to five pairs of dorsomedian apodemesand no dorsolateral sclerotizations. Venter with 5–11 pairedmedian apodemes in rows, paired lateral row of sclerotiza-tions (Fig. 4A). Females (except C. thisbe) have two pairs ofwhite dots on posterior abdomen lateral to spinnerets, whichmay be fused into continuous white area (C. irenae). Epigy-num a simple sclerotized tongue (C. episinoides, C. perroti, seeFigs 12E,F and 19C,D), a ventral swelling (C. clathrata,C. simoni, C. irenae, Figs 1B–E, 6B,C and 7B,C), or a simple

transverse sclerotization (C. thisbe, Fig. 25B,C). Posteriorlyorientated small, inconspicuous copulatory openings, oftencovered by integument. Entelegyne vulva simple, pairedspermathecae connected to copulatory openings by tubularcopulatory duct (short, or coiled in C. irenae, Fig. 7D), ferti-lization duct originates adjacent. Spinnerets (Figs 4D–F,10E,F and 15C–F) of typical nephiline condition (see Hor-miga et al. 1995): ALS with ‘normal PI field’ where PI spigotbase is nearly as long or longer than the shaft (Griswold et al.1998: ch. 69, fig. 48B), major ampullate spigot and a nubbin,PMS with sparse aciniform field, and nubbin, PLS withaggregate spigots embracing flagelliform (observed inC. episinoides, C. clathrata, and C. irenae, condition unknownin C. simoni and C. thisbe) and with two cylindrical spigots ofnormal size, mesal being peripheral. Exception is C. perroti,where aggregate spigots of PLS triad were found apart fromflagelliforms (Fig. 22D–F).

Male (Figs 13A–D and 20A–G): prosoma length rangesfrom 1.3 to 2.5, total length from 2.8 to 4.9. Prosoma piri-form with narrow cephalic region. All eyes lack tapetum,lateral eyes widely separated, PLE larger than PME. Cheliceralboss striated (Fig. 16B), with fewer striae than in females.Chelicerae with three prolateral, three retrolateral teeth,5–15 cheliceral denticles. Sternum, legs as in female.Opisthosoma oval, dorsoventrally flattened, truncated poste-riorly (Fig. 20A–D), with dorsal scutum (Figs 17C–E and23E), three pairs of dorsal median apodemes. No dorsolateralsclerotizations. Ventral sclerotizations as in female (Figs 17Aand 23C). Two pairs of white dots on posterior abdomenlateral to spinnerets. Palp Nephila-like, with globular tegulumand prominent subtegulum (Fig. 13A) [in C. perroti subtegu-lum is distally fused to tegulum (Fig. 24A,C)]. Paracymbiumflat, rectangular, with invagination (Figs 5F, 13A, 18B and24B). Smooth narrow embolic conductor envelopes embolus,and is approximately at 90 degrees to bulb axis. Embolicconductor attached to embolus and tegulum via membrane(Fig. 13C), longer than cymbium, relatively straight(Fig. 13A–C). Embolus base separated from tegulum bymembrane (Fig. 20F).

R.Jocque & L.Baert) — cl014/f1 (Female), cl014/j1(Immature), cl014/m1 (Male).Etymology. Unknown.Diagnosis. Clitaetra clathrata females differ fromC. episinoides, C. perroti, and C. thisbe by the carapace andfrontal abdomen with numerous white setae, by the darkbrown area around leg spine-sockets, and by the female epigy-num with a ventral swelling (Fig. 1B–E). Clitaetra clathratafemales differ from C. irenae by having the copulatory open-ings positioned on the posterior sclerotization (Fig. 1C,E).Clitaetra clathrata females can be distinguished from C. simoniby having grooved booklung covers, fewer cheliceral bossstriae (c. 150–250, Fig. 3E), by four retrolateral cheliceralteeth (Fig. 3D), and by the posterior epigynum lacking anotched appearance (Fig. 1C,E). A unique feature of

C. clathrata is the thorny abdominal cuticle of the female(Fig. 4C). Male C. clathrata can be distinguished from those ofall other species by the short and wide embolic conductor: theembolus width (in mesal view) is less than one third of themaximum length of the embolic conductor (Fig. 2B).Description.

Note. The species diagnosis below separates the holotypefemale of C. simoni from morphologically similar C. clathrata.In the absence of available males and additional female mate-rial, I here tentatively recognize C. simoni as valid.Etymology. The species epithet was devised as a patronymhonouring Eugene Simon (see Taxonomic History).Diagnosis. Clitaetra simoni female differs from C. episinoides,C. perroti, and C. thisbe by the carapace and frontal abdomen

with numerous white setae, by the dark brown area aroundleg spine-sockets, and by the female epigynum with a ventralswelling (Fig. 6B,C). Clitaetra simoni female differs from thatof C. irenae by having the copulatory openings positioned onthe posterior sclerotization (Fig. 6C). The species resemblesC. clathrata in general somatic morphology, but can be distin-guished from the latter by the smooth booklung covers, morenumerous boss striae (c. 300), and by the three retrolateral

m1 (Male); St. Lucia National Park, Fanies Camp, 28°0′S,32°30′E, 24 Jan 1991 (coll. V. D. & B. Roth) — CL002/f1(Female).Etymology. The species epithet, a noun in genitive case, is apatronym honouring my wife Irena Kuntner.Diagnosis. Copulatory openings of C. irenae females are noton the posterior sclerotized epigynal margin, as in all otherClitaetra species, but are well anterior to the margin(Fig. 7C), within a pair of sclerotizations. The shape of thelong copulatory ducts coiling around the fertilization ducts(Fig. 7D) is unique within the genus. Males can be distin-guished from other Clitaetra species by the shape of the tegu-lum (broader than long, Fig. 8A) and the embolic conductor(Fig. 8A,B), which is relatively longer than in C. clathrata andstraighter than in C. episinoides.Description.

lateral teeth, and 24 denticles. Cheliceral boss not prominent,striae hardly visible with dissecting scope (but see variationand Fig. 9C,D). Appendages. Legs whitish-yellow, with darkbrown spine-sockets and spines; tarsi brown. Sustentaculum(tarsus IV) conspicuous. Leg I length 15.3 (Fe 4.5, Pa 1.3, Ti3.6, Me 4.3, Ta 1.7). Leg formula 1-2-4-3. Opisthosoma(Figs 7A and 10A) 4.4 long, 3.3 wide, 2.3 high, pentagonal,dorsoventrally flattened, with five pairs of dorsomedian apo-demes (fourth and fifth inconspicuous); dorsum with grey,brown, white pattern (illustrated in Fig. 7A from holotype),venter with broad white midband extending from epigastricfold to spinnerets, and broken white pattern around spin-nerets. Eleven pairs of ventromedian apodemes, two posteriorpairs of inconspicuous ventrolateral sclerotizations visibleunder dissecting microscope (but, paired row of lateral scle-rotizations visible on SEM images, Fig. 10A,B).

Diagnosis. The females of C. episinoides can be distinguishedfrom all other Clitaetra species except C. perroti by the pres-ence of a ‘tongue’ epigynum (Figs 12E,F and 15B) withposteriorly hidden copulatory openings. Clitaetra episinoidesdiffers from C. perroti by the combination of the followingcharacters: epigynum an elongated, well sclerotized buttransparent tongue with spermathecae visible anterior to thetongue (Fig. 12E); spermathecae separated from the poste-rior epigynum tongue edge by two spermatheca diameters ormore (Fig. 12E,G); female venter medially dark (Fig. 12C);female carapace elongated (carapace length to width ratio1.3); opisthosoma long (length to width ratio 1.4). MaleC. episinoides differ from C. irenae and C. clathrata by thenarrow and curved embolic conductor (Fig. 13A,B). Unlikein C. perroti, the subtegulum of C. episinoides males is not fusedto the tegulum (Figs 13A and 18A,B), and the embolus base has

few denticles distally (Fig. 18D). The ratio of embolic con-ductor length to cymbium length in male palp when observedfrom ectal side is more than 1.5 : 1 and the sperm duct in thetegulum (Fig. 13A,D) is relatively narrower than in C. perroti.Description.

coloration in preserved specimens from yellow to red-brown.Scutum pronounced in most males, dorsum colour variable.Cheliceral denticle numbers 11–15. Ventral apodemes andsclerotizations as in female.Distribution. Known only from the Indian Ocean islandsMayotte (Fr.) and Njazidja (= Grande Comore, ComoroIslands) (Fig. 26). Contra Hormiga et al. (1995) and Platnick(2005) the species does not occur in Madagascar (see below).

Note on distribution. There has been confusion about thegeographic distribution of Clitaetra episinoides. Simon (1889)described it from the French island of Mayotte in the IndianOcean. When describing the second species of the genus,C. perroti from Madagascar, Simon (1894) provided readerswith a generic diagnosis, listing its type species (C. episinoides),and the distribution of the genus (islands Mayotte andMadagascar). Roewer (1942: 925) listed the distribution of

C. episinoides as ‘Mayotta’, but Bonnet (1956: 1100) errone-ously cited the distribution as ‘Madagascar, Comores’. Thesame is true for the catalogues of Platnick (1989: 305, 1997:452, 2005). The species does not occur on Madagascar.Natural history. See ‘Biology’ of Clitaetra. Label data fromGrande Comore suggest the species can be found at eleva-tions up to 700 m.

Diagnosis. Clitaetra perroti females differ from all otherClitaetra species, except C. episinoides, by the presence of a‘tongue’ epigynum (Figs 19C–F and 22A,B). Clitaetra perrotiis approximately half to two thirds the size of C. episinoides.Further, the following combination of features separatesC. perroti females from C. episinoides: epigynum an opaquetongue, with spermathecae rarely visible through the cuticleanterior to the tongue (Fig. 19C–F); spermathecae separatedfrom the posterior tongue edge by one spermatheca diameteror less (Fig. 19E,F); venter medially white (Fig. 19B); cara-pace and opisthosoma broader than in C. episinoides (carapacelength to width ratio 1.1, opisthosoma length to width ratio1.1). A unique feature of C. perroti are the aggregate glandspigots of the female posterior lateral spinneret triad, whichare apart from the flagelliforms (Fig. 22F). Clitaetra perrotimales differ from all other Clitaetra species by the subtegu-

lum distally fused to the tegulum (Figs 20E and 24A,C).Clitaetra perroti males further differ from C. episinoides bynumerous denticles distally on embolus base (Fig. 24D,E), bythe broader sperm duct in the tegulum (Fig. 20E,G), andby the shorter embolic conductor (the ratio EC length tocymbium length less than 1.4 : 1).Description.

DiscussionClassificationThis study corroborates the monophyly of Clitaetra, Heren-nia, Nephila and Nephilengys, all classically considerednephilines. The nephiline placement as sister to other arane-oids minus araneids disputes all previous hypotheses. Suchplacement will be further tested with a denser taxonomicsample. However, it now seems clear that Nephilinae asdefined by Hormiga et al. (1995) is polyphyletic, does notcontain Phonognatha, and does not group with tetragnathids.Therefore, I propose a revised classification elevating theclade (Clitaetra + (Herennia + (Nephila + Nephilengys))) tofamily rank, Nephilidae. The newly defined subfamilyNephilinae is proposed to contain the clade (Herennia +(Nephila + Nephilengys)). The remaining nephilid clade con-taining all Clitaetra species is here proposed to be treatedas another subfamily, Clitaetrinae, which is currently ident-ical in composition and phylogenetic definition to the singlegenus within (Clitaetra), a so called Gregg’s Paradox (e.g. Ruse1971).

In a rankless classification system such as the PhyloCode(Cantino & de Queiroz 2004) Gregg’s Paradox does not exist.There has been a vigorous debate on the pros and cons ofrankless vs. Classical Linnaean classification systems (areview is in preparation). In a rankless system, a new cladename does not have to be accompanied by naming theremaining clades, but in classical Linnaean classification itdoes. For example, the only well supported clitaetrine clade(Fig. 27B) contains the three currently known (and probablyseveral unknown) mainland African species (C. irenae +(C. clathrata + C. simoni)). It makes some sense to name the clade,simply for the sake of discussing the interesting biologicalaspects it offers (biology, biogeography, anatomy, etc.). How-ever, naming a species group in the Linnaean classificationsystem requires a rank, and if the new name, Afroetra, receivesthe genus rank, one would have to also name, at the genusrank, the two clades with two (C. episinoides + C. perroti ) anda single species (C. thisbe), respectively, to avoid their para-phyly. This study uses Linnaean ranks, but to some extentavoids disruptive changes in species nomenclature by treatingthe three newly named clades (Afroetra, Clitaetra, Indoetra)arbitrarily at the subgenus level. To follow rankless classifica-tion (Cantino & de Quieroz 2004), the clade Afroetra couldbe newly named and defined, with no forced adjacent newclade names and no disruption to Clitaetra species nomenclature.Thus, another Gregg’s Paradox, this time in the monotypicsubgenus Indoetra, would be avoided. A simple alternative inthe Linnaean system, of course, is not to name new clades,and if they do merit discussion, give them informal names,a standard practice in recent araneological phylogeneticliterature (Scharff & Coddington 1997; Griswold et al.1998; Agnarsson 2004, 2005; Agnarsson & Kuntner 2005).

However, none of the alternatives provides a formal lineagename. The biogeographic implications of basal nephilids domerit discussion and more research and thus the (subgeneric)names Afroetra, Indoetra and Clitaetra are used here.

Nephilid spider lineage Clitaetrinae • M. Kuntner

54 Zoologica Scripta, 35, 1, January 2006, pp19–62 • © The Norwegian Academy of Science and Letters 2006

BiogeographyNephilid spiders recorded from the Dominican amberinclude Nephila (Wunderlich 1986) and a number of unplacedfossil genera (Wunderlich 2004), but no clitaetrine fossilsare known, and no clitaetrines (or Herennia) have been re-corded from the neotropics. Clitaetra cladistic biogeography(Fig. 29) suggests the area cladogram ((Africa + Madagascarwith adjacent islands) + Indian subcontinent), which does notagree with the currently understood continental drift theory(Brown & Lomolino 1998; McLoughlin 2001), becauseIndian and Madagascar species do not group. If the Gondwa-nan distribution of Clitaetrinae is explained solely by vicari-ance with no dispersal events, the phylogeny allows roughclade age estimations (in Fig. 29 minimum clade age is given).The west–east Gondwana split separating S America + Africafrom the remainder of Gondwana (including Madagascar and

India) is estimated at 160 Myr. The monophyly of the Africanand Madagascar species would suggest that the clade predatesthe split. Thus, assuming no intercontinental dispersalevents, the clade Afroetra + Clitaetra must be at least 160 Myrold, and its sister clade Indoetra, by definition, of the sameage. All more inclusive clades can be assumed to be older.Thus, the basal clitaetrine split between the Indian andMadagascar (plus African) species probably well predates thesplit between India and Madagascar (60 Mya), and its sisterclade, Nephilinae, must be of the same age (more than 160Myr old). Likewise, the nephilid clade (and its sister cladewith the remaining araneoids) cannot be less than 160 Myrold, predating the separation of (Madagascar + India) from(Australia + Antarctica) (125–130 Mya).

Given the above estimates of clade ages it should come asno surprise that the basal nephilid dichotomy and the deep

Fig. 29 Nephilid relationships with Clitaetrageographic distributions, simplified after thesuccessively weighted phylogeny. Proposedclassification combines Linnaean ranks withphylogenetic clade definitions. Minimum ageof the clade Afroetra + Clitaetra estimated bythe split of west and east Gondwana (see text).

araneoid relationships (see also Kuntner 2005) are poorlysupported due to lack of solid morphological and behaviouralsynapomorphies.

ConclusionsThe biology of Clitaetra remains insufficiently known. Theclade Clitaetrinae is sister to all other nephilid lineages(Figs 27–29) and thus its scored features will affect the nephi-lid character polarizations. A potential rediscovery of Clitae-tra thisbe, not recorded since the original description from SriLanka, would enable testing as to whether the morphologicaland behavioural data here presented hold also for the basal-most clitaetrine species. Unfortunately, the type locality ofC. thisbe (Galle, Sri Lanka) has been heavily deforested in thelast century and was lately disastrously affected by the 2004tsunami. However, it is likely that there are further (Indoetra)species on the Indian subcontinent awaiting discovery.
