Clypeal margin with either 0 or 2 teeth, and 2 teeth at junction of frons and clypeus. Anterior part of underside of pronotum not excavated anteriorly. Some species with keels and tubercles on head.

Elytra with 8 striae. Striae faintly impressed, impunctate to moderately punctate. Intervals slightly convex. Epipleuron narrow, with small excavation on ventral margin below humerus. Dorsal surface with short bristles, and a line of longer setae along posterior margin.

Hind wings: Fully developed.

Legs: Fore tibiae with 4 teeth (4th small) on the outer edge. Middle coxae parallel. Mid and hind tibiae with transverse ridges. Middle tibiae with 2 strong spurs of unequal length.
