Diagnosis.

This plus Singilis kolesnichenkoi sp. n., Singilis klimenkoi sp. n. and Singilis timuri sp. n. constitute a quartet of species consisting of small-bodied beetles, with convex, subovate elytra and long pubescence (Figs 8-11). Singilis kabakovi alone has the elytra with weak, diffuse, grey postmedian band, sometimes reduced to sutural spot and intervals 2, 4 and 6 without setiferous pores.

Description.

Length 5.2-5.8 mm. Red-brown, with postmedian sutural infuscation on elytra (Fig. 8).

Head smooth, microsculptured, uniformly punctate, punctures separated by 1-2 their diameters. Clypeus impunctate. Eyes moderately convex, with a few relatively long setae at posterior margin. Second supraocular seta located just anterad the posterior margin of eye. Temples short and smooth. Scape with a very long seta at 2/3 of its length and a few thin setae towards the apex; pedicel with a single, apical band of setae; antennomere III with a few additional setae towards apex. Antennae pubescent from the basal fourth of antennomere IV.

Pronotum smooth, shinier than head, 1.14 times as wide as head, 1.2 times as wide as long, widest at marginal setae. Anterior margin straight, anterior angles slightly prominent, sides very broadly and evenly rounded, conspicuously sinuate towards posterior angles, which are acute. Punctation irregular, sparser and shallower than on the head. Explanate lateral margin rapidly widened from apex, broad and flat to slightly reflexed at base. Lateral and apical setae very long. Posterior pore right in front of angle. Basal grooves punctate. Pronotal base extended in a rounded median lobe. Furrow variable. Microsculpture subtle, slightly transversely polygonal.

Elytra infuscate behind middle, infuscation may reach just one or two innermost intervals, or extend to lateral margins. Intervals 1, 3, 5, 7, 8 pubescent throughout, and interval 6 pubescent in apical half, each with an irregular row of large setiferous pores. Setae as long as the width of interval 4 at its widest. All intervals convex at basal third and slightly convex from there to apex. Interval 7 convex from base to mid-length. Microsculpture deep, irregularly polygonal. Apex slightly sinuate. Striae deep, punctate, shallower at apex.

Legs brownish yellow. Tarsomere V with 3 pairs of ventral setae. Mes- and metepisterna smooth. Claws with 4 moderately long teeth. Venter evenly brownish yellow. All abdominal sterna pubescent, pubescence as long as on elytra.
