-
Posterior lateral margin of pronotum distinctly curved inward at posterior angle which has a distinct, small acute projection behind pore (

Elytral striae weakly impressed, giving intervals a weakly convex appearance, most evident on middle of disc; female terminal abdominal ventrite with apical medial surface glossy, glabrous and finely punctate, distinctly different from rest of surface, males with this surface entirely setose and coarsely punctate (
