Body subhexagonal; in dorsal aspect with marked constriction between pronotum and elytron; with distinct constriction in profile. Rostrum with median ridge and pair of submedian ridges, intervening furrows punctate; punctures each with long erect scale; epistome with transverse, angulate ridge forming median denticle. Pronotum anterolaterally angularly projecting; with distinct subapical constriction; disk rugose-punctate, punctures each with slender suberect to subrecumbent scale; with median ridge. Elytra with striae deeply impressed, each with row of stout suberect bristles; intervals costate to carinate, almost nude; interval 3 most prominent; interval 7 swollen subapically, laterally projecting.
