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

each species one specimen deposited in BMNH, both are females, which are conspecific and well correspond with description of C. (E.) acutangulus, although he had in his disposal two distinct species originated from the LEWIS' collection. One of this species was named by him before (REITTER 1879) as C. sibiricus. REITTER in his latest key (REITTER 1919) distinguished three species, which was followed by the author of this paper (KlREJTSHUK 1992). However, after recent checking of the type series it became clear that these species should be named as: C. (E.) acutangulus REITTER, 1884 = C. (E.) cingulatus REITTER, 1884, syn. n.; C. (E.) sibiricus REITTER, 1879 = C. (E.) cingulatus sensu REITTER, 1919 and KlREJTSHUK, 1992. C. (C.) cingulatoides NAKANE, 1959 also belongs to this complex, although this may be a synonym of C. (E.) acutangulus rather than C. (E.) sibiricus. Subfamily Amphicrossinae Amphicrossus angusticlavis sp. n. (Figs 23-33) Specimens examined - "Mentawei, Sipora, Sereinu, V-VI.94, Modigliani" (named by GROUVELLE as A. discolor and .4. houchardi) (holotype, male, MSNG, one paratype, ZISP);"Sar.", "68.106", (named by A. MURRAY as "discolor") (one paratype, BMNH);"Malaise trap, Sample 1", "malaise trap sample, base-camp, stunted, hill forest, Bukit, Monkobo", "Borneo: Sabah, Bukit Monkobo, 51°48'N, 116°58'E, 7-13.viii.1987, 900 m, A.H. Kirk-Spriggs" , "NMW Sabah (Borneo Expedition, NMW.Z. 1987.094" (one paratype, NMC). Description of male (holotype) - Length 5.3, width 3.4, height 1.2 mm. Moderately convex dorsally and slightly ventrally; dorsum, meso- and metasterna brownish, but the remainder of underside and appendages reddish to reddish brown; dorsum with a faint shine, and underside moderately shining; body with slightly conspicuous fine golden hairs, about 3 times as long as distance between their insertions and dorsum also with sparser and longer hairs, forming on elytra longitudinal rows; pronotal and elytral sides with dense cilia, consisting of hairs about as long as tarsal claws; paramedial brushes of long hairs situated almost in anterior fourth (these hairs slightly longer than hairs in cilia) (Fig. 23). Head with distinct punctures, about as large as eye facets, interspaces between them about as broad as a puncture diameter or slightly broader, densely and smoothly microreticulated. Pronotum with slightly smaller and sparser punctation and with more relief sculpture on interspaces. Elytra about as punctured and sculptured as head, although microreticulation on interspaces more raised. Pygidium with very small and very sparse distinct punctures, interspaces between them transversely wavy microreticulated. Prosternum with obsolete puncturation and relief irregular sculpture, but its process with distinct punctures, smaller than half an eye facet in diameter, interspaces between them much broader than a puncture diameter and smooth. Metasternum with distinct and dense punctures, somewhat larger than eye facets, interspaces between them less than a puncture diameter and rather smoothly microreticulated. Ventrites nearly microgranulose, densely microreticulated to alutaceous.
