Rostrum irregularly rugose-punctate; with short, clavate, suberect scales; epistome at middle with indistinct, curved ridge. Pronotum with shallow subapical constriction; disk coarsely punctate; each puncture containing erect clavate scale inserting at posterior rim; surface dull, microreticulate. Elytra with striae deeply impressed, in front of each puncture with claviform, suberect scale; intervals costate; surface dull, coriaceous, microreticulate; interval 7 subapically forming distinct ridge. Femora edentate. Metafemur subapically without stridulatory patch. Abdominal ventrite 5 flat, microreticulate, with sparse scales. Penis (Fig. 78b) with apex asymmetrically extended on the left; apical extension short; basal orifice ventrally without rim; apodemes short, 0.5 × as long as body; ductus ejaculatorius with bulbus.
