Head, in dorsal view, short, wider than pronotum; crown-face transition rounded; ocelli on anterior margin, slightly mesad of antennal pits and well separated from eyes; frons slightly inflated, median portion often flattened, surface with transverse striae or transverse irregular striae, lateral margins slightly convergent ventrad and with short setae; clypeus surface finely rugose, with thin setae mainly near apex; maxillary plate very narrow, produced ventrally as far as clypeus apex; gena with thin setae, ventrolateral margin slightly excavated ventrad of eye, completely concealing proepisternum; antennal ledge carinate and slightly oblique, not concealing antennal base. Pronotum, in dorsal view, with anterior margin rounded, extended anterad of eyes medially, posterior margin slightly excavated; surface with many erected short setae, with transverse striae except near anterior margin; lateral margins slightly convergent anterad, carinate, shorter than eye length; in lateral view convex and moderately declivous. Exposed part of mesonotum and scutellum approximately as long as pronotum length, with many erect setae; mesonotum surface rugose except lateral angles shagreen. Forewing with venation distinct, many erect setae between veins, sometimes with extra crossveins and veinlets. Hind leg femoral setal formula 2:2:1 or 2:1; AV row formed by short, thin and close setae in basal third and thicker, spaced setae distally; PD row formed by small setae intercalated with 4–5 long setae; IC row formed by double row of fine setae continuous with AV row; second tarsomere pecten with 2 platellae flanked by 2 tapered lateral setae on inner and 1 on external corner. Abdominal sternite II of male with pair of internal apodemes elongated, extending to posterior margin of sternite IV.
