Rostrum dorsally with broad median costa and pair of submedian ridges; intervening furrows each with row of subrecumbent scales. Pronotum with disk densely punctate with coarse punctures; interspaces between punctures subglabrous, smaller than punctures´ diameter. Elytra with striae marked by distinct rows of small punctures; basal margin bordered by transverse row of deeper punctures joining stria 8; sutural interval with additional row, other intervals subglabrous, with few interspersed punctures. Femora edentate; anterior surface coarsely punctate, each puncture with recumbent white narrow scale. Metafemur with dorsoposterior edge denticulate; subapically with stridulatory patch. Metatibia subapically with dense cluster of setae. Abdominal ventrites 1–2 concave, subglabrous, laterally with suberect scales; ventrite 5 at middle with deep depression, subapically densely punctate and laterally with few erect scales. Penis (Fig. 4b) with sides of body weakly subparallel, in apical 1/3 with lateral swelling; apex subtruncate, with median extension and sparse setae; apodemes 1.5 × as long as body of penis; transfer apparatus complex; ductus ejaculatorius without bulbus.
