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

Diagnosis - This new species is rather similar to S.fracta REITTER, 1884 and S. imperialis GROUVELLE, 1903, but differs from both in the more slender and much darker body, peculiar shape of the protibia and distinct structure of aedeagus. Etymology - The name of this new species is devoted to OTTÓ MERKL, curator of the Coleoptera Collection of HNHM, who collected many interesting specimens in Taiwan and other areas and who was assisting to the author research during many years. Cyllodes pseudoliteratus sp. n. (Figs 136-137, 146-151) Description of male (holotype) - Length 3.3, width 2.3, height 1.0 mm. Strongly convex dorsally and slightly convex ventrally (Fig. 146); bright reddish, antennái club and metasternum brown; a pair of paramedial spots at the middle, 3 pairs of spots and base of pronotum and a complex pattern on elytra blackish to black; dorsum glabrous, and underside with moderately dense, fine and short hairs. Head with distinct punctures, about as large as eye facets in diameter, interspaces between them somewhat broader than a puncture diameter, smoothly alutaceous. Pronotal surface similar to that on head, but punctures markedly smaller and rather sparser, and interspaces completely smooth. Elytral surface with punctures as those on pronotum, but considerably sparser and with longitudinal rows of punctures about as large as eye facets, separated by a puncture diameter or narrower; interspaces between punctures smoothly acutaceous. Surface of pygidium, prosternum and ventrites with not quite distinct, rather large and irregular punctures, about 3 times as large as a puncture diameter, interspaces between them slightly narrower than a puncture diameter on pygidium and much narrower on underside, densely and finely (more or less smoothly) microreticulated. Metasternum with distinct punctures, somewhat larger than eye facets in diameter, interspaces between them about half a puncture diameter and smoothly microreticulated. Head slightly convex, slightly longer than distance between moderate large eyes (consisting of moderately small facets). Subtruncate labrum (Fig. 147) and mandibles slightly exposed from under frons. Antennae slightly longer than head wide, their club (Fig. 148) composing somewhat more than 1/3 of total antennái length, about twice as long as wide, antennomere 3 about twice as long as antennomere 2, the latter somewhat longer than antennomere 4. Pronotum evenly and strongly convex. Scutellum large and subtriangular. Elytra steeply sloping, subsutural lines weakly expressed only at apices, which are widely and separately rounded, forming a clear suturai angle. Pygidium with subtruncate apex, from under which apex of anal sclerite is exposed. Last labial palpomere slightly longer than wide, with convex sides and slightly narrowed apically. Mentum rather subtriangular than subpentagonal, about 2.5 times as wide as long. Antennái grooves well outlined and slightly deepened, slightly convergent posteriorly, the least distance between them nearly twice as broad as mentum wide. Prosternum sharply carinate, with shortly flattened and very short process (Figs 136-137), obliquely abrupt in median plane. Mesosternum deeply excavate and sharply carinate along the middle. The distance between mesocoxae about 3 times broader and that between metacoxae about 2.5 times broader than that between metacoxae. Metasternum subflattened, without a visible median suture, about 1 and 2/5 as long as prosternum with process, its anterior edge between coxae straight and posterior one shallowly emarginate. Submesocoxal lines subtransverse, deviating laterally from the middle of cavities, intercoxal line between mesocoxae distinct and closely approached to anterior edge of metasternum. Ventrite 1 about
