Holotype, male (Fig. 96a). Length 2.56 mm. Color black, antenna and tarsi ferruginous. Body subovate, extremely uneven, in dorsal aspect with distinct constriction between pronotum and elytron; in profile without such constriction. Rostrum in basal half medially carinate, coarsely punctate, sparsely setose; epistome with transverse, angulate ridge. Pronotum with marked subapical constriction; laterally projecting with marked angular protrusions; disk longitudinally costate-tuberculate, in basal half medially with prominent ridge. Elytra with striae deeply incised; intervals undulating-costate, some areas markedly elevated, constricted along 2 transverse lines, subglabrous, with sparse minute punctures and setae; apex extended ventrad, slightly beak-shaped, ventrally truncate. Metafemur with dorsoposterior edge simple, in apical third with transverse row of small suberect setae, subapically with stridulatory patch. Disk of abdominal ventrites 1–2 excavated; ventrite 2 projecting dentiform over elytral edge in profile. Aedeagus (Fig. 96b) with apex medially pointed; transfer apparatus complex, symmetrical; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.09–2.56 mm. Female rostrum dorsally with median costa in basal half; epistome simple.
