Diagnostic description.
Holotype, male (Fig. 88a). Length 2.63 mm. Color black; legs dark ferruginous; antenna light ferruginous. Body subrhomboid; with marked constriction between pronotum and elytron; in profile evenly convex to subapical constriction of pronotum. Rostrum with pair of sublateral furrows converging posteriorly on forehead; pair of submedian furrows shallow; epistome forming angulate ridge and median denticle. Pronotum with marked subapical constriction, sides weakly converging, behind subapical constriction with angular protrusions; disk with pair of deep furrows curving anteriad joining subapical constriction; center of disk coriaceous, sparsely punctate; laterally rugose. Elytra subovate, apically subangulate; striae weakly impressed; surface dull, microgranulate, almost nude, with sparse minute setae; interval 7 subapically forming distinct, weakly denticulate ridge; apex extended ventrad, slightly beak-shaped in profile. Femora edentate. Meso- and metatibia in basal half widened, subapically narrowed. Metafemur with denticulate dorsoposterior edge, subapically without stridulatory patch. Aedeagus (Fig. 88b) with body parallel-sided; apex medially extended into subtruncate tip; transfer apparatus thick spiniform; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.30-2.63 mm. Female rostrum in apical half medially subglabrous, with two rows of punctures; epistome simple.
