Point of antennal insertion concealed dorsally by the clypeus. Mentum mostly glabrous, moderately sinuate anteriorly. Gula well developed. Posterior tentorial pits moderately separated. Pronotum with indistinct systematic punctures present, sometimes bearing short setae. General punctation on head and pronotum very shallow, with distinct, very fine microreticulation. Prosternum tectiform; bearing moderately dense covering of setae. Mesosternum bearing a high, ventrally directed protuberance. Scutellum slightly longer than wide. Elytra evenly convex, not flattened dorsally; with sharp sutural stria in at least posterior half; margins not explanate. Elytra with general punctation uniformly distributed; with rows of serial punctures not well developed to nearly absent; punctures not microreticulate. Epipleura wide, slightly wider than the width of anepisternum 3. All femora with tibial grooves; ventral surface of pro and mesofemora with dense pubescence on at least basal three fourths; metafemora with pubescence restricted to extreme base and along anterior margin. All tarsi with five segments; tarsomeres 1–4 subequal in length; tarsomere 5 on pro and mesotarsus as long as tarsomeres 1–4 combined, and twothirds as long on metatarsus. Both tarsal claws small and similar on all legs. Abdomen with five exposed flat ventrites covered with dense, fine pubescence; first ventrite without median carina; fifth ventrite arcuate posteromedially, marginal setae larger than other pubescence on ventrites.
