Rostrum dorsally with rows of coarse punctures each containing one recumbent seta; medially with indistinct subglabrous costa; epistome indistinct, with median denticle. Pronotum with disk densely punctate; each puncture containing fine, recumbent seta; interspaces between punctures subglabrous. Elytra with striae marked by rows of small punctures and fine hairlines, more distinctly impressed near base; intervals subglabrous, with interspersed punctures; stria 8 along humerus with row of coarse punctures. Femora edentate. Meso- and metafemur with anteroventral ridge weakly crenate; anterior surface densely coarsely punctate-rugose, each puncture with recumbent piliform scale.
