Kirejtshuk, A. G.: New taxa of Nitidulidae (Coleoptera) from the Indo-Malayan fauna

Colopterus vieticus sp. n. (Figs. 151-154) Material. 1 *, holotype: N. Vietnam. Thainguyen, 300 m. 5 Febr. 1963, O. KABAKOV (ZIN). Male, holotype. Length 2.3, breadth 1.2, height 0.6 mm. Elongate oval, flattened; reddish with black lateral and apical parts of elytra, rather shiny; with short, moderately dense and fairly well contrasting yellowish pubescence; pronotal and elytral sides finely and shortly ciliate. — Head almost flat with labrum moderately exposed and distinctly bilobed. Surface with oval punctures about as large as eye facets, separated by distance equal to 1.5 puncture diameter. Intervals nearly smooth. Antennae 3/4 as long as head broad, their club elongate nearly twice in length 1/3 of total antenna! length. — Pronotum with narrowly bordered sides and wide basal border. Surface with oval, almost shallow punctures twice as large as eye facets forming indistinct transverse rows, distance between which being somewhat less than distance equal to a puncture diameter, space with mesh reticulation slightly smoothed. — Scutellum subtriangular, its central surface nearly same as on pronotum and smooth and unpuctured at sides. — Elytra with well raised shoulders and sides narrowly explanate. Surface with distinct longitudinal rows of punctures as large as ones on pronotum. interstices with rows of small and shallow punctures and space smooth; punctures of both sizes bearing hairs as long as ones on rest of dorsum and arranged in regular lines. Pygidium as well as exposed tergite with small and hardly visible punctures, closely reticulated. — Ventral surface shiny and less pubescent than dorsal one; thoracic sterna with shallow and sparse punctures somewhat larger than eye facets, intervals with traces of reticulation; sternites with similar puncturation but space between punctures with relief and strongly closed reticulation. Distance between intermediate coxae subequal to one between hind one and almost twice more than one between fore. Caudal marginal lines of intermediate, and hind coxal cavities following closely their hind edges. Last abdominal sternite bisinuate at apex. — Tibiae feebly widened towards apicis. their greatest width somewhat less than that of antennái club. Femora twice wider than tibiae. Fore tarsi 2/3, and intermediate and hind about 1/2 as wide as tibiae, tarsal claws thin and simple. — Genitalia: Aedeagus well sclerotised. Diagnosis. — C. vieticus sp. n. is rather distinct from its other Indo-Malayan congener (C. modiglianii GROUVELLE, 1897) fairly well common in Indochina in its body coloration, the sharp hind corners of the prothorax, the puncturation as a whole, including punctural lines on the elytra as well as its genital structures.
