МасШтаб: 1,2 мм (Рис. 12); 1,3 мм (Рис. 16); 1,5 мм (Рис. 19).

Pronotum shape variable, either maximum width at apical 3/4 (more trapezoid) or at middle (more quadrate) (Fig. 12); posterior angle obtuse, slightly toothed, basis not emarginate. Foveae well marked and usually punctured.

Elytra moderately widened backward, side narrowed toward basis, humerus toothed, striae smooth or with traces of punctures, intervals flat in females and slightly convex in males; disk with distal seta on 3rd stria but it often varies as it is found in interval 3, close to stria 2 or may be absent.

Prosternal process forming an obtuse ridge, rounded and emarginate on bottom, ventral segments punctured including metepisterna (Fig. 13), this as long as wide (L/ W 1.0). Males with mesotibia somewhat enlarged apically and metatibia with traces of crenulation in apical internal side.

Median lobe of aedeagus slightly bent ventrally; apical shaft asymmetrical, more narrowed in left side and prolonged in the right side (Fig. 14); membranous sac devoid of teeth and only moderately open on dorsal view. Spermatheca dilat- ed apically, spermathecal duct relatively short (Fig. 15)
