Diagnosis. Beetles small to medium-sized (2–5 mm), nearly circular in dorsal view, convex in lateral view. Dorsum metallic or nonmetallic, unicolored or with stripes or spots. Vertex large, moderately convex. Frontal calli poorly to moderately developed, triangular, flat to slightly convex, entering into interantennal space, sulci surrounding antennal calli poorly developed. Eyes small to medium-sized, antennal sockets separated by a distance of about two times socket diameter. Frontal ridge short, wide, flat to moderately raised; anterofrontal ridge flat to moderately raised. Antenna hardly reaching middle of elytron, distal antennomeres widened. Labrum deeply incised. Maxillary palps long; palpomeres 2, 3 moderately enlarged; last conical. Pronotum transverse, without impressions, anterior coxal cavities open behind, anterolateral callosity large and raised. Elytra with irregular punctation, apically narrowed; epipleura wide, horizontal, reaching near apex. Hind wing present or absent. Thoracic sternites with raised process in middle, prosternal intercoxal process with longitudinal vertically raised ridge, process on metasternum usually circular. Metacoxa greatly enlarged. Metatibia curved in dorsal view; dorsal surface with sharp lateral margin; spur long. Metatarsomere 1 as long as or longer than following tarsomeres combined; tarsal claw appendiculate. Vaginal palpi fused basally. Spermathecal duct not coiled.
