This species is most similar to the allopatric Singilis jedlickai , new species. The two species can be diagnosed easily by microsculpture of pronotum, i.e., Singilis jedlickai has conspicuously microreticulate pronotum. The aedeagus also differs dramatically (Figs 42-43).
Length 6.8-7.0 mm. Reddish brown, with apical third of elytra black (Fig. 24).
Head shiny, densely minutely punctate, punctures sometimes almost confluent in frontal depressions, separated by 1-2 diameters on the frons. Microsculpture scarcely visible. Clypeus with a few punctures near lateral margins. Eyes large and bulging, with 3-4 setae at posterior margin. Second supraocular seta located just anterad the posterior margin of eye. Temples smooth, 2.6 times as short as length of eye. Scape with a very long seta at 2/3 of its length and a few short thin setae towards the apex; pedicel with a band of apical setae; antennomere III with two bands of setae (at mid-length and at apex). Antennae pubescent from mid-length of antennomere IV.
Pronotum shiny, without microsculpture, 1.12-1.14 times as wide as head, 1.33-1.4 times as wide as long, widest just behind the marginal setae. Anterior margin straight, anterior angles effaced, sides evenly rounded, considerably to slightly sinuate towards posterior angles, which are acute and protrude as minute denticle. Punctation, especially on disc, sparse, irregular, somewhat sparser than on head, denser towards lateral margins, where may be confluent and rugose. Lateral explanate margin widened basad lateral setae, broad and flat at base. Posterior pore right in front of angle. Basal grooves small and shallow. Pronotal base extended in a rounded median lobe. Furrow fine.
Intervals 1, 3, 5 and 7 each from base to apex with an irregular row of sparse pores bearing extremely short, barely visible setae. At humerus, interval 7 flat or weakly convex and as wide as the adjacent intervals. Microsculpture delicate, polygonal. Apices slightly sinuate. Striae finely punctate. Intervals slightly convex at base and almost flat at apex.
Legs brownish yellow. Tarsomere V with 4 pairs of ventral setae. Propleuron, mes- and metepisterna smooth, shiny. Claws with 3 short teeth and one minute denticle at base. Venter uniformly testaceous. Abdominal sterna smooth, shiny, with sparse long pubescence.
Aedeagus - Fig. 42. Aedeagal median lobe arcuate, apex long; internal sac with small ventral microtrichial field composed of small spines.
