This species is most similar to the sympatric Singilis makarovi , new species. This species shares with Singilis makarovi the presence of 2-3 irregular and dense rows of big setiferous pores on all intervals of elytra, bearing long setae. The two species can be diagnosed easily by the propleura, wavy rugate in Singilis solskyi , smooth in Singilis makarovi .
Length 6.8-8.0 mm. Head, pronotum, basal third of elytra, thorax, legs, and antennae red-brown; suture, apical 2/3 of elytra, and abdominal sterna black (Fig. 5).
Head microsculptured, deeply irregularly punctate, punctures near eyes sometimes almost confluent, on the frons separated by more than three diameters and on the vertex by 1-2 diameters. Clypeus sparsely punctate. Eyes large and bulging, with numerous strong setae at posterior margin. Second supraocular seta located just anterad the posterior margin of eye. Temples smooth. Scape with a very long seta and a few short thin setae scattered throughout; pedicel with a band of apical setae; antennomere III with numerous setae on apical half. Antennae pubescent from the basal third of antennomere IV.
Pronotum shinier than head and elytra, 1.18 times as wide as head, 1.34 times as wide as long, widest in front of marginal setae. Anterior margin straight, anterior angles effaced, sides very broadly and evenly rounded, slightly sinuate towards posterior angles, which are rectangular. Disc shiny, very sparsely and irregularly punctate, punctures separated by 2-5 diameters, transversely confluent towards lateral margins. Lateral margins narrow, flat towards base. Posterior pore right in front of angle. Basal grooves shallow, rugose, confluently punctate. Pronotal base extended in a rounded median lobe. Furrow fine and reduced. Microreticulation faint.
Elytra pubescent. Each interval with 1-2 irregular rows of setiferous pores from base to apex. Setae as long as mesotarsomere IV. Interval 7 flat, as wide as adjacent intervals. Microsculpture polygonal, deep and irregular, same as on head. Apices slightly sinuate. Striae slightly punctate, shallower on disc and at apices. Intervals slightly convex at base, flat at apex.
Tarsomere V with 5 pairs of ventral setae. Propleura rugose. Mes- and metepisterna smooth. Claws with 5 teeth, basal teeth very small. All abdominal sterna pubescent; pubescence long and dense, as on elytra.
Aedeagus - Fig. 30. Median lobe apex elongate, slightly downturned at narrowly rounded apex. Internal sac with one large and compact spicular field made up of mid size spines.

This species was described as Glycia bicolor (Solsky, 1874) (Types: Samarkand, Karasu, near Katty-Kurgan, 25.IV.1869; and Ulus riv., 1869). Now that Agatus has been synonymized with Singilis , Singilis bicolor (Solsky, 1874) has become a junior homonym of Singilis bicolor Rambur, 1837, and should be replaced. We propose the name solskyi nom. n.for Singilis bicolor (Solsky, 1874), nec Rambur 1837.
Named after the Russian entomologist Semyon Solsky who first described this species.
