Kirejsthuk, A. G.: On the fauna of Nitidulidae (Insecta, Coleoptera) from Taiwan with some taxonomical notes

Amphicrossus hirtus sp. n. (Figs 43-54) Specimens examined - (In addition to paratypes from Taiwan, see above.) "Sulawesi Utara, Dumoga-Bone N.P., May 1985", "At light", "Clarke camp, Lower montane forest, 1 140 m", "Project Wallace, B.M. 1985-10" (holotype, male, BMNH); paratypes: "light trap 2, 50 m aqbove ground, 21.viii.79, S. L. Sutton", "Brunei: Labi, Bukit Teraja, 60 m, Mxt. Dipt. Forest, B.M. 1983-39" (1, ZISP); "N. Borneo, H. v. Oertzen" (1, ZMB); "India", "Bowring, 63.47*" (2, BMNH); "Thailand (Loei), Na Haeo (bio. Station), 05-12.V.2001, Light trap, Constant & Grootaert" (1, IRSN); "Thailand 91, Thanon Thong Chai, D. Král & V. Kubán", "9-14. V. 1991, Chiang Dao, 350 m, Vit Kubán" (1, NMB); "Cambodia (Angkor), Preah-Kahn. Temple, 31.V.2003, Light trap, L. Constant & K. Smets" (1, ZISP); "Philippines, 150 m, Palawan, Port Barton, 14-18. Dec. 1990, Bolm" (1, NMB). In contrast to some other species of the genus, the conspecific females can be recognized and included in the type series. Description of male (holotype) - This new species is rather similar to A. angusticlavis sp. n., so some characters shared by both species are omitted in the description. Length 5.4, width 3.2, height 1.5 mm. Moderately convex dorsally and slightly ventrally; dorsum brownish, anterior part of head with mouthparts, transparent sides and longitudinal patches on pronotum, large patch on disc of each elytron, in the centre of which there is a small dark (blackish) spot, sides of pygidium and underside lighter (reddish to yellow brownish); dorsum with a faint shine, and underside slightly shining; body with rather conspicuous yellowish golden subrecumbent hairs, 2-3 times as long as distance between their insertions and dorsum also with sparser and very long and very stout at base blackish hairs, forming on elytra longitudinal rows (longer hairs somewhat suberected; pronotal and elytral sides with dense cilia, consisting of hairs somewhat shorter than tarsal claws; paramedial brushes of long hairs situated closely before the middle (these hairs much longer than hairs in cilia and longer than width of antennái club) (Figs 44-45). Head with distinct punctures, markedly smaller than eye facets in diameter, interspaces between them about as broad as a puncture diameter and finely cellularly microreticulated. Pronotum and elytra with distinct punctures, somewhat smaller than those on head, interspaces between them 2-3 times as broad as a puncture diameter or even broader, with dense, cellular and somewhat smoothed microreticulation. Pygidium with very small and very sparse distinct punctures, interspaces between them cellularly microreticulated. Prosternum with shallow and dense puncturation and smoothed sculpture, but its process with distinct small punctures (about half an eye facets, interspaces between them somewhat narrower than a puncture diameter and smooth). Metasternum with distinct and dense punctures, about as large as eye facets, interspaces between them about a puncture diameter and rather smoothly microreticulated. Ventrites with distinct punctures about as large as eye facets, interspaces between them about as broad as a puncture diameter and smooth or smoothed, but on hypopygidium punctures becoming smaller and traces of sculpture more visible. Eyes with moderate facets in diameter (comparatively larger than in most congeners). Antenna! club (Fig. 46) comprising about 2/7 of total antenna! length, slightly longer than wide, antennomere 3 slightly longer than antennomere 2 and twice as long as antennomere 4. Pronotum (Fig. 43) with posterior edge at posterior angles distinctly and moderately oblique. Elytra about as long as broad combined, their apices rather widely rounded and slightly oblique than subtruncate (as those in many congeners). Pygidium rather widely rounded than subtruncate at apex. Mentum subquadrangular, about 2.5 times as wide as long. Prosternum sharply carinate, but its process (Fig. 47) flattened and rather widened at very widely rounded posterior edge. Median plate of mesosternum (Fig. 48) almost
