Elytra with striae marked by minute punctures and indistinct hairlines; basal margin bordered by transverse row of deeper punctures, curving along humeri; intervals flat, subglabrous. Femora edentate. Meso- and metafemur with anteroventral ridge distinct, simple. Metafemur with anterior surface coarsely punctate, each puncture with elongate recumbent silvery scale; with dorsoposterior edge weakly denticulate; subapically with stridulatory patch. Abdominal ventrites 1–2 concave, subglabrous; ventrite 5 flat, coarsely punctate. Penis (Fig. 36b) with sides converging in basal 1/2, anteriorly subparallel; apex subangulate, with few setae; basal orifice of body ventrally with angulate extensions; apodemes 2.2 × as long as body of penis; transfer apparatus complex, small, elongate; ductus ejaculatorius with indistinct bulbus.
