This species is most similar to the sympatric Singilis cingulatus. The two species can be diagnosed easily by different color of legs, i.e., Singilis cingulatus has femora and apical part of tibiae piceous to black (Figs 2–3).
Length 4.3–5.3 mm. Body elongate; head and pronotum red-brown, elytra black with red-brown basal band and a common preapical round red macula reaching interval 6. Venter light brownish yellow, sterna sometimes darker; legs yellow (Fig. 1).
Head microsculptured, deeply and irregularly punctate, punctures sometimes almost confluent in frontal depressions, on the frons separated by 3–5 their diameters, towards the base of head, by 1–2 diameters. Clypeus with a few punctures at lateral margins. Eyes large and bulging, with numerous strong setae at posterior margin. Second supraocular seta located just anterad the posterior margin of eye. Temples smooth, 2.4 times shorter than length of eye. Scape with a very long seta and a few long thin setae; pedicel with a band of apical setae; antennomere III with scattered setae on apical half. Antennae pubescent from the mid-length of antennomere IV.
Pronotum shinier than head, microsculptured, cordate, 1.08–1.11 times as wide as head, 1.2–1.25 times as wide as long, widest just behind the marginal setae. Anterior margin straight, anterior angles effaced, sides slightly sinuate towards posterior angles, which are rectangular or slightly acute. Disc sparsely irregularly punctate, somewhat less densely than head; punctures at lateral margins confluent, surface rugose. Disc convex to lateral margins, which are very narrow. Posterior pore right in front of angle. Basal grooves shallow, rugose, confluently punctate. Pronotal base extended in a rounded median lobe. Furrow short and shallow.
Each interval with a row of setiferous pores along the middle from base to apex. Setae as long as the width of interval 2. Microsculpture almost isodiametric. Apices slightly sinuate. Striae deep, punctate. Intervals weakly convex at base, flat at apex.
Legs brownish yellow. Tarsomere V with 4 pairs of ventral setae. Propleuron smooth, even, mes- and metepisterna strongly microsculptured. Claws with 4 teeth, 3 relatively long and one (basal) minute. All abdominal sterna with long pubescence.
Aedeagus – Fig. 28. Internal sac without apparent spicules or microtrichial patches.
Varies in size, ventral colour, and the extent of dark elytral pattern (may be reduced).
Types collected in “Samarkand" (now Uzbekistan) and near Shahrud (n. Iran) (Solsky, 1874: 35).
