Introduction

Agrilus acutus (Thunberg, 1787) is one of the oldest species described from the Orientalregion and is also the most widely distributed (Fig. 16) and the most variable species inthis region. Subsequently, many related taxa have been described, which can be character-ized by the outer angles of the elytral apices being sharply spinate. Because of the accumu-lation of taxonomic problems, only selected species are treated in this revision.

The taxa examined herein can be divided into two groups of very closely related spe-cies (see key to species): acutus-group (A. acutus; A. dianthus Kerremans, 1892; A. coeles-tis Deyrolle, 1864; A. acanthopterus Harold, 1869 and A. cyaneofasciatus Théry, 1930)and paradiseus-group (A. paradiseus Obenberger, 1924 and A. mikusiakorum new spe-cies).

507ZOOTAXA Material and methods

The following abbreviations are used in the text: [p], preceding data ‘printed’; [h], preced-ing data ‘handwritten’. Square brackets “[ ]” are used for my remarks and addenda; thebackslash “\” is used to separate data from different labels. Abbreviations for museumsand collections are:

BMNH = The Natural History Museum, London, England; EJCB = Collection of E.Jendek, Slovak Academy of Sciences, Bratislava, Slovakia; GNCV = Collection of G.Novak, Vienna, Austria; ISNB = Institut Royal des Sciences Naturelles de Belgique, Brus-sels, Belgium; MCSN = Museo Civico di Storia Naturale "Giacomo Doria", Genova, Italy;MNHN = Muséum national d´Histoire naturelle, Paris, France; NMEG = Naturkundemu-seum Erfurt, Erfurt, Germany; NMPC = Národní muzeum, Prague, Czech Republic;USNM = The United States National Museum of Natural History, Smithsonian Institution,Washington D. C., USA; UZIU = Uppsala University, Uppsala, Sweden; ZMUC = Univer-sity of Copenhagen, Zoological Museum, København, Denmark; ZMUK = UniversitätKiel, Zoologisches Museum, Kiel, Germany.

In the synonymy, specific names are cited chronologically and in agreement with gen-der of the genus of current assignment, followed by the author, the date and the page num-ber for the original description. In the parentheses, the original generic assignment and theoriginal rank for species-group name if other then species (e.g., subspecies, variety, formor aberration) is specified. Preoccupied and replacement names are also annotated inparentheses. Because the original and current generic assignments are specified, the authoris not enclosed by parentheses as required by ICZN (Article 51.3). Unavailable names arecited separately. The reason for considering a name as unavailable is discussed in the text.

Subsequently fixed name-bearing types were provided with a printed red label bearingall relevant data: e.g., type status, species name in original combination and correct spell-ing, author, year of the publication and an inscription “E. Jendek design.” along with yearof designation.

The type locality is quoted in the language and form of the original citation, the orderof these data is sometimes altered from the original sequence. Label data of subsequentlyfixed name-bearing types are literally transcribed and enclosed in quotation marks. To pre-serve original locality data from original descriptions and specimens, my complementaryinformation and updates are consistently given in “[ ]”.

Localities have been updated according to the GEOnet Names Server of the NationalImagery and Mapping Agency (NIMA) or Microsoft Encarta Interactive World Atlas2001. Localities written in Cyrillic characters were transliterated to Latin characters.Transliteration was based on the British standard.

Unavailable namesAgrilus diacanthus Haan. Unpublished, unavailable name (ICZN, Article 11.1). Cited

by Dejean, (1836: 93) as a valid name of species and by Gemminger & Harold (1869:1436) as a synonym of A. armatus.

Agrilus diacanthus Dejean. Unavailable name. Kerremans (1892a: 244, 255) cited thename diacanthus Dejean as a synonym of A. acutus. Dejean did not propose the name asnew, he attributed it to Haan.

Agrilus acutus aberration asphaltipennis Obenberger. Proposed as an infrasubspecificname and thus is an unavailable name (ICZN, Articles 1.3.4, 45.5).

Remarks. Agrilus acutus is relatively variable in size (5.5–8.9 mm) and color (varioushues of blue and green). Dorsally black individuals occur rarely (Sumatra, Java, Sulawesi).The form of medial sulcus on the frontovertex (deep-shallow) and the maximum width ofthe pronotum (at middle–at base) varies even on specimens from the same locality. Theprincipal characters distinguishing it from A. dianthus is the wider pronotum (see key) andthe longer and sharper spines on outer apical angle of each elytron (Figs. 9–11). However,the form of emargination of apices varies considerably at both species (Figs. 9–15). Aede-agi of all species of the acutus-group are rather uniform, without distinctive characters.There are no principal differences between the populations of A. acutus from western(India, Sri Lanka) and eastern (Indonesia, Papua New Guinea) localities except a slighttrend to glabrous elytra (obsolete elytral pubescence) at specimens from the East.

Type locality. [Laos] Luang Prab. [= Louangphrabang province], Vieng Vai [site unlo-cated]. No type locality was cited by Bourgoin, but presumably “Indo-Chine française” asindicated in the title. The type locality is stipulated from the place of origin of the lecto-type (ICZN, Article 76.2.).

Agrilus dorri Bourgoin, lectotype &, designated by Descarpentries & Villiers (1963),MNHN: “Long Xuyen Cochinchine Dorr [p] \ Agrilus Dorri A. Bourgouin [black ink]Type [red ink] [h]”. Number of syntypes is unknown. Descarpentries & Villiers (1963: 54)by the mention about type: “Type de dorri au Muséum de Paris” validly fixed the lectotype(ICZN, Article 74.6). As a synonym of A. acutus dianthus proposed by Descarpentries &Villiers (1963: 54).

Type locality. [Vietnam] Cochinchine: Long Xuyen [10°23'N, 105°25'E].Remarks. Agrilus dianthus has an allopatric distribution with A. acutus and has been

considered as a subspecies of A. acutus. The examination of numerous specimens hasrevealed that A. dianthus is a generally larger (6.6–10.2 mm) and well distinguished spe-cies (see remarks at A. acutus and key to species).

All records from peninsular SE Asia cited under the name A. acutus or its synonymspertains to A. dianthus, for example Baudon 1961: 75 (as A. acutus). Very interesting is asingle record of A. dianthus from the Indonesian part of Borneo.

Although proposed as a vari-ety of A. coelestis the diagnosis does not unambiguously reveal that the name was pro-posed as an infrasubspecific entity, since the taxon was diagnosed also by morphologicalcharacters: “spina apicali breviore divergens”. Following ICZN, Article 45.6.4, such aname should be deemed subspecific from the original publication.

Type locality. [Indonesia, Lesser Sunda Islands] Flores [Island] [8°30'S, 121°00'E].Remarks. Agrilus coelestis is characterized by generally smaller size (6–8.6 mm),

obliteration of pubescence and by sexual dichroism (see key to species).

507ZOOTAXA Head: frontovertex convex with broad, deep medial longitudinal sulcus extending

from epistoma to vertex, surface densely, coarsely punctate; vertex 2.1 times as wide aswidth of eye; eyes large, convex, not protruding beyond head outline, lower margin of eyedistinctly extends beyond upper margin of antennal socket. Antennae rather short, barelyextending to pronotal midpoint when laid alongside, antennomeres 4–5 sharply serrate,antennomeres 6–10 obtusely serrate.

Pronotum: 1.8 times wider than long, trapezoid, strongly convex, widest at base; ante-rior margin without medial lobe, almost straight, distinctly narrower then posterior margin;anterior pronotal sides straight converging anteriorly; disk sparsely, coarsely, transverselyrugose with broad medial longitudinal impression extending from posterior almost to ante-rior margin; lateral impressions absent. Prehumerus long, sublinear, sharp and rib-like,originating from posterior margin in close vicinity of posterolateral angles and conjoinedwith lateral margin in anterior fourth of pronotal length. Marginal and submarginal carinaefeebly sinuate, converging posteriorly, submarginal carina becoming obsolete in anteriorand posterior parts.

Scutellum: 1.3 times longer than wide, narrowly subquadrate in front, sharply triangu-lar behind, without transverse carina, feebly impressed on disk.Elytra: 3.2 times longer than wide, widest at base, gradually tapering beyond middle thenabruptly attenuate to apices; lateral margins of apices slightly expanded, apex sinuatelyemarginate, emargination with series of adsutural denticles and sharp spine on outer angle;disk with obvious, broad adsutural impression covered with golden toment in apical third.Humeri without costa.

Last tergite: with long medial spine on apex, ventrally visible between emargination ofelytral apices.

Ventral side: prosternal lobe declivous, arcuately emarginate at middle; prosternal pro-cess large, distinctly converging between coxae, than abruptly subovally expanded; diskflat, roughly densely punctate. Last ventrite very narrow, evenly arcuate apically, withindication of faint notch. Ventrolateral parts of thorax and abdomen clothed with long,decumbent, white pubescence.

Legs: Metatarsi shorter than metatibiae; basal metatarsomere 1.2 times longer as threefollowing together; tarsal claws cleft near middle, inner tooth shorter and broader.

Diagnosis. Closely related to A. paradiseus from which differs by 1) long, medialpronotal impression; 2) straight prehumerus; 3) adsutural elytral impression with goldentoment reaching to apices; 4) lateral margin of apices slightly expanded and 5) apices arc-uately sinuate.
