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

some places smoothed and becoming indistinct, interspaces between them somewhat smoothed. Prosternum with irregular and obsolete punctures, interspaces between them irregularly and relief microreticulated to smoothed. Meso- and metasterna with almost regular punctures, somewhat smaller than eye facets in diameter, interspaces between them about as broad as a puncture diameter, more or less smoothed. Ventrites with almost regular punctures, about 1/4 as large as eye facets in diameter, interspaces between them about 2—4 times as broad as a puncture diameter, more or less smoothed to smooth. Head very widely subdepressed behind antennái insertions, much shorter than distance between eyes (composed of moderately large facets and with very short interfacetal setae). Antennae 11/14 as long as head broad; club (Fig. 142) about 1 and 1/4 as long as wide and with antennomere 9 widest, composing nearly 2/7 of total antennái length; scape strongly dilated and nearly as long as wide, antennomere 3 about 1.5 times longer than each of antennomeres 2 and 4. Labrum with subtransverse anterior edge and rounded at sides (Fig. 141 ). Mandibles well raised and rather projecting from under labrum. Pronotum with widely explanate sides (about as widely explanate as width of antennái club), longitudinal median depression and rows of paramedial shallow depressions on disk, its anterior angles moderately projecting, its base with well raised border and with distinct apices of posterior angles, its sides regularly arcuate. Scutellum with rounded apex. Elytra with evenly slopped to widely explanate sides (somewhat less widely explanate than pronotal ones), their apices forming a joint arc; subsutural lines expressed in distal 2/5 and follow closely to suture. Pygidium rather subtruncate than widely rounded at apex. Mentum subsexogonal, about 2.5 times as wide as long. Antennái grooves well expressed only at mentum, arcuately convergent at both head base and mouth. Subparamental concavities as continuing as grooves. Last labial palpomere about twice as long as wide and somewhat widened apically. Distance between mesocoxae about subequal to and that between metacoxae nearly 1.5 times greater than that between procoxae. Prosternai process strongly dilated before almost transversely truncate apex pressed to mesosternal surface (almost twice as wide as antennái club). Mesosternum slightly convex, without medial carina. Metasternum slightly depressed before its angularly excised posterior edge between coxae. Submesocoxal lines follow closely posterior edge of cavity arcuately deviating from the latter only at lateral end of cavity. Ventrite 1 about twice as long as hypopygidium; apex of the latter widely rounded. Epipleura very wide, at base about 1.5 times as wide as antennái club (or slightly wider at base than femora), and somewhat elevated laterally. Protibia (Fig. 143) very narrow in proximal 3/5, strongly widened and curved at distal 2/5, its most width about 1 and 1/3 of antennái width. Meso- and metatibiae narrow and simple, slightly narrower than antennái club. Femora with anterior and posterior edges gently convex, pro- and mesofemora about 1.5 times, metafemur about twice as wide as corresponding tibiae. Tarsi very narrow and short, tarsomeres 1-3 weakly lobed, tarsomere 5 longer than tarsomeres \-A combined, claws simple and narrow, with bisetose empodium between them strongly reduced. Aedeagus well sclerotized (Figs 144-145). Female - Differs from male only in simple protibia and absence of anal sclerite, apex of which can be partly exposed in males. Ovipositor well sclerotized, rather long and usual configuration. Variability - Length 6.5-8.0, width 3.0-4,0 mm. Pubescence and puncturation vary in a comparatively wide range. One paratype has obsolete puncturation and rather smoothed sculpture on almost entire pronotum and elytra. This paratype bears a rather bald dorsum and pronotal sides sinuates in anterior half.
