Diagnostic description
Holotype, male (Fig. 36a). Length 2.64 mm. Color black; tarsi and antenna ferruginous. Body subovate; with weak constriction between pronotum and elytron; in profile evenly convex. Rostrum sparsely squamose with suberect scales; in basal half with median carina; in front of eyes with flat lateral extensions; subapically weakly scabrous; epistome smooth, posteriorly forming transverse, angulate ridge, with weak median denticle. Pronotum without subapical constriction, densely coarsely punctate; laterally above procoxa with fovea. Elytra with striae moderately incised on disk; intervals flat, with rows of small punctures; laterally subglabrous; apex subangulate, with pair of sublateral knobs; extended ventrad, slightly beak-shaped. Femora edentate. Metafemur dorsally sparsely squamose, with weakly denticulate dorsoposterior edge; subapically with stridulatory patch. Abdominal ventrite 2 projecting dentiform over elytral edge in profile. Aedeagus (Fig. 36b) apically rounded, sparsely setose; with complex, symmetrical transfer apparatus; ductus ejaculatorius with bulbus. Intraspecific variation. Length 2.28–2.64 mm. Female rostrum with median carina and transverse ridge of epistome less distinct.
