Diagnostic description.
Holotype, male (Fig. 39a). Length 3.41 mm. Color black; antenna and tarsi ferruginous. Body subovate; without constriction between pronotum and elytron; in profile evenly convex. Rostrum in basal half with distinct median carina and pair of indistinct sublateral ridges; with sparse rows of white scales; subapical third subglabrous, weakly punctate; in front of antennal insertion with weak constriction. Eyes large, medially approximate. Pronotum densely punctate with small punctures; sides separated by indistinct edge bearing dense row of punctures; laterally above coxa sparsely squamose with white scales. Elytral striae distinct with small punctures; intervals flat, subglabrous, sparsely punctate with minute punctures; basal margin straight, simple. Femora with anteroventral ridge distinct, at base abruptly ending and forming markedly projecting blunt angle; edentate. Mesofemur and metafemur dorsally densely squamose with white scales but partly abraded. Metafemur with smooth dorsoposterior edge; subapically without stridulatory patch. Aedeagus (Fig. 39b) with apodemes ca. 3 × as long as body; sides of body in basal half subparallel, markedly sclerotized, mid-portion of body weakly sclerotized; apex subangulate; transfer apparatus flagelliform, longer than body; ductus ejaculatorius subapically with bulbus. Intraspecific variation. Length 3.38-3.41 mm. No female specimen available.
