ABSTRACT

Acmaeodera (Acmaeodera) bellamyola Volkovitsh, new species, from Yunnan and Sichuan provinces, China, isdescribed, illustrated, and compared with its congeners from the eastern Palaearctic and Oriental regions.

Key Words: metallic wood boring beetle, taxonomy, Polycestinae, Sichuan, Yunnan, species-groups

Representatives of the subgenus AcmaeoderaEschscholtz s. str. are not abundant in the easternPalaearctic region and adjacent areas of the Orientalregion. Only six species from three species-groupsare known from this area so far (Volkovitsh 1979,1986): Acmaeodera semenovi Obenberger, 1935(A. semenovi species-group), Acmaeodera yunnanaFairmaire, 1888 (A. yunnana species-group),Acmaeodera cincticollisKerremans, 1893, Acmaeoderasommailae Baudon, 1963, Acmaeodera medvedeviVolkovitsh, 1976, and Acmaeodera fabricianaVolkovitsh, 1983 (A. brunneipennis species-group).Species-groups A. semenovi and A. yunnana aremonotypic and endemic in southwest China (Yunnan,Sichuan), while species of the A. brunneipennisspecies-group occur also in the western Palaearctic.The record of the new species described hereincontributes to the knowledge of Acmaeoderini ofSoutheast Asia.

MATERIAL AND METHODS

Specimens cited below are deposited in thefollowing collections, abbreviated as: DGCC – D.Gianasso collection, Castelnuovo Don Bosco, Italy;HMCM – H. Mühle collection, Münich, Germany;IZCAS – Institute of Zoology, Chinese Academy ofSciences, Beijing, China; VKCB – Vítězslav Kubáňcollection, Brno, Czech Republic; ZIN – ZoologicalInstitute RAS, St. Petersburg, Russia.Images of adults were taken using a Leica

MZ-9.5 stereomicroscope with a mounted LeicaDFC-290 camera. Measurements were taken usingan eyepiece micrometer in a MBS-9 stereomicro-scope. The range of measurements for structuresare given in parentheses following their mean inthe description. Genitalia images were taken usinga Bresser-Biolux light microscope with an integratedimaging system.

Note: All mentionedspecimens have additional red (type) labels: “Holo-type (or Paratype), Acmaeodera (s. str.) sinensisVolkovitsh sp. n.” (unavailable name).

Diagnosis. This species belongs to theA. brunneipennis species-group (formerly calledthe A. elater species-group) (Volkovitsh 1979,1986), differing from other eastern Palaearctic andOriental species of this group by the following com-bination of characters: coloration of elytra light,without metallic sheen or distinct elytral patternof markings; complicated shape of pronotal sidesand presence of deep medial depression; pronotalsculpture changing from reticulate to punctatetoward anterior portion of disc; aedeagus and ovi-positor structures are unique. Acmaeodera bellamyolais most similar to A. medvedevi from southernMongolia and northern China, which differs fromthe A. bellamyola as follows: elytra and dorsalpubescence uniformly dark brown; pronotal sides

arcuately converging from widest point at posteriorthird to anterior angles; pronotal disc without medialdepression (but deep prescutellar fossa present);pronotal sculpture uniformly reticulate; aedeagusof different structure (female unknown).Description. Body (Figs. 1, 2) of medium size,

mean length 7.6 (6.6–8.9) mm, mean width 2.1

Body elongate, 3.56 (3.35–3.68) timesas long as pronotum at base; flat, without dorsalcurvature; black, with coal or feeble steel sheen;elytra fulvous on disc with brown base, humeralswellings and apical third uniformly greyish brownto light brown; body dorsally covered with erect,

Male. Aedeagus as in Figs. 7, 8.Female. Ovipositor (Fig. 9) very short, ventrite-

like.Ecological Data. No larval host is known.

According to V. Kubáň (personal communication),who collected a series of this species near Baishuivillage, Yunnan on 11 July 1990 in the early daytime,A. bellamyola and A. semenovi were collectedtogether on the violet flowers of ?Convolvulus sp.on a mountain slope with solitary standing, veryold trees of Pinus sp. and Quercus sp. In the latedaytime, the beetles were found in the crevices ofold dry stumps of Pinus sp., while the beetles ofA. semenovi were found in the crevices and underthe trunk bark of Quercus sp. Based on this infor-mation, it is difficult to conclude that either the
