Singilis kolesnichenkoi sp. n.

Material examined.

Holotype: ♀, Iran, Kerman, Sirjan, 8 km N Balvard, 11-12.V.2007, leg. A. Anichtchenko (ZIN).

Diagnosis.

Among the species consisting of small-bodied beetles, with convex, subovate elytra and long pubescence, Singilis kolesnichenkoi is diagnosable by the smooth head, and almost smooth, cordate pronotum; rows of setiferous punctures on intervals 3-5 widely interrupted; setiferous pores on all intervals large; body coloration uniformly red brownish.

Description.

Length 4.6 mm. Uniformly red-brown, with venter and legs paler (Fig. 9).

Head smooth, distinctly microsculptured, very sparsely minutely punctulate, punctures sometimes barely visible. Clypeus and labrum distinctly microsculptured. Eyes moderately large, each with 3 long setae behind. Second supraocular seta located immediately basad the posterior margin of eye. Temples long, smooth. Scape with a very long subapical seta and several small setae; pedicel and antennomere III each with a single band of apical setae. Antennae pubescent from the mid-length of antennomere IV.

Pronotum smooth, cordate, 1.07 times as wide as head, 1.3 times as wide as long, widest just behind marginal setae. Anterior margin straight, anterior angles effaced, sides broadly and regularly rounded, slightly sinuate towards base, posterior angles obtuse. Disc very sparsely punctate. Anterior margin with a few big punctures, basal part with large punctation reaching along lateral margins 1/3 of pronotal length. Lateral margin narrowly explanate from apex, slightly wider at base. Posterior pore right in front of angle. Basal grooves shallow. Pronotal base extended in a rounded median lobe. Furrow long and fine. Microsculpture as on the head.

Elytra suboval, convex, with strong polygonal microsculpture. Each interval with a series of very large setiferous pores in a single row. In the discal part of intervals 2-5 pores may be smaller or rows interrupted. Setae as long as the combined width of intervals 1 and 2. Scutellum smooth and shiny, without microsculpture. Elytral apices truncate, weakly obliquely sinuate, rounded at suture. Striae crenulate at base, finely punctate elsewhere. Intervals slightly convex.

Legs pale brownish yellow. Tarsomere V with 2 pairs of short ventral setae. Claws with 4 minute denticles near base. Abdominal sterna smooth, shiny, with sparse short setae.
