Pronotum with disk densely punctate; interspaces between punctures subglabrous, subequal to punctures´ diameter; median line impunctate. Elytra with striae marked by dense rows of small punctures; basal margin bordered by transverse row of deeper punctures; striae 7–9 near base with large punctures; sutural interval with additional row, other intervals subglabrous. Profemur with anteroventral ridge simple; meso- and metafemur with anteroventral ridge crenate-denticulate, ending with indistinct denticle in apical 1/4; anterior surface of femora coarsely punctate, each puncture with scale.
