Elytral pattern (Fig. 8–13) uniform, consisting of one small subbasal spot, one medial narrow, transverse, slightly oblique stripe, and one small subapical spot. Head relatively slender. Labrum dark bronze-brown to blackish. Mandible (Fig. 3–4) distinctly elongated, with narrow shaft and long teeth, at least four teeth (occasionally up to six) between molar dentition (covered by labrum) and apex. Pronotum slender, length greater or slightly smaller than width; maximum width near base; sides anteriorly converging. Male: foretarsus weakly enlarged, with narrow brush of hairs on tarsomeres 1–3.

Mesepisternal coupling sulcus of female narrow and deep. Glossy humeral area of female elytra distinct, although variably extended among species. Apex of female elytra variably modified, strongly convex (Fig. 9) or acuminate-truncated (Fig. 11, 13).
