Description. Head subvertical in front, slightly elongated and narrowed behind eyes; mandibles rather long, with sharp apex, crossed when closed; maxillae ( Fig. 3 b) relatively reduced, palps long and with dense setae, foursegmented, the third segment shortest, terminal segment with apex truncated; galea with long setae, lacinia reduced; eyes large, emarginated, prominent, lower lobes anteriorly approaching genal margins. Antennae longer (male) or shorter (female) than the body, flagellomeres flattened, flagellomeres I to VIII prominently angulate lateroapically in females (making flagellum weakly serrate), in males the lateroapical angle produced into a long flattened spine (making flagellum pectinate); scape stout, shorter than other antennomeres except pedicel; last antennomere longest; third shorter (male) or longer (female) than fourth; fourth slightly shorter than (male) or subequal to (female) fifth. Prothorax with lateral margin in the form of a carina extending from base nearly to apex, curved downward to (but always retaining some distance from) outer angles of the procoxal cavities; latter cavities widely open posteriorly, intercoxal process broad, with broadened apex. Mesonotum widely and deeply emarginated anteriorly, with a median line, stridulatory plate absent. Elytra broader than prothorax, about three times as long as the maximum width near base, gradually narrower apically, and rounded at apex. Hind wings have a very complete plesiomorphic venation similar to that of Philus ; females with normal elytra and wings. Legs rather long, fringed with hairs and pubescence; pro- and mesotibiae with short dents or teeth (shorter than surrounding pubescence) on outer side; tibial spur formula 2/2/2; tarsi with the third joints cleft, first joint shorter than the second and third combined. Fore coxae prominent, strongly transverse.
