Body subovate, in dorsal aspect with weak constriction between pronotum and elytron; with distinct constriction in profile. Rostrum with median ridge and pair of irregular submedian ridges, intervening furrows each with sparse row of mesad directed setae; epistome with transverse ridge. Pronotum coarsely punctate, laterally reticulate, submedially interspaces longitudinally rugose, with median costa; with sparse, slender, subrecumbent scales. Elytra with striae deeply impressed, with row of coarse punctures, each puncture containing one suberect bristle; intervals costate, subglabrous; suture incised, dull microreticulate, bordered by row of punctures. Femora with simple, crenate anteroventral ridge. Metafemur subapically with stridulatory patch. Abdominal ventrite 5 dull, coriaceous, at middle with shallow impression, with distinct median carina. Penis (Fig. 93b) with sides of body slightly diverging in straight line; apex subangulate, subglabrous, sparsely setose; orifice with complex sclerites; transfer apparatus compact, symmetrical, apically with large anchor-shaped sclerite; apodemes 3.3 × as long as body; ductus ejaculatorius without bulbus.
