Instantly recognizable by the combination of cordate pronotum, elongate and flat elytra, intervals with single uninterrupted row of conspicuous setiferous pores bearing long setae. In sympatric Singilis solskyi  intervals of elytra with 2-3 irregular and dense rows of big setiferous pores.


Length 5.9-6.2 mm. Red-brown, with wide piceous postmedian band on elytra (Fig. 4).

Head smooth, very distinctly microsculptured, finely punctulate, punctures separated by 2-4 diameters. Clypeus with few punctures at base. Eyes normal, with 3-5 setae at posterior margin. Second supraocular seta located just anterad the posterior margin of eye. Temples long, smooth. Scape with a very long subapical seta and several short setae; pedicel and antennomere III each with a single band of apical setae. Antennae pubescent from the mid-length of antennomere IV.

Pronotum cordate, smooth, 1.1 times as wide as head and 1.27 times as wide as long, widest right behind marginal setae. Anterior margin straight, anterior angles effaced, sides strongly sinuate towards base. Posterior angles acute, prominent. Lateral margin narrow. Discal punctation sparse and shallow, somewhat sparser than on head. Posterior pore right in front of angle. Lateral and basal setae long. Basal grooves punctiform. Pronotal base rugosely punctate, extended in a rounded median lobe. Microsculpture as on head.

Each interval of elytra with a single regular row of long sparse setae, interval 8 with two rows of setae. Setae as long as the width of interval 3 at its widest. Pores deep, punctiform, separated by three diameters. Microsculpture of elytra and scutellum irregularly polygonal, shallower than on head and pronotum. Elytral apices weakly obliquely sinuate, rounded at suture. Striae deep and punctate. Intervals almost flat throughout.

Legs pale brownish. Tarsomere V with 4 pairs of ventral setae, two basal pairs very short. Claws with 3 denticles on basal half. Venter entirely brownish yellow. Episterna smooth. All abdominal sterna with long pubescence.
