Body subovate; in dorsal aspect with marked constriction between pronotum and elytron; with distinct constriction in profile. Rostrum with median and pair of submedian ridges, most prominent at level of antennal insertion, anteriorly rather indistinct; with sparse rows of suberect scales; epistome at middle with dorsoposteriad directed acute denticle. Pronotum coarsely punctate-reticulate, each puncture with one clavate suberect scale; with indistinct subapical constriction. Elytra with striae deeply impressed, each with row of suberect clavate scales; intervals subcarinate, microreticulate. Metafemur subapically with stridulatory patch. Abdominal ventrite 5 flat, sparsely covered with small clavate scales. Penis (Fig. 52b) with sides of body in basal half subparallel, in apical half converging to subtruncate apex; ostium with large trapeziform sclerite; apodemes 1.8 × as long as body; transfer apparatus with subovate central fig and coiled spiniform transfer process; ductus ejaculatorius with distinct bulbus.
