Diagnostic description
Holotype, male (Fig. 31a). Length 2.63 mm. Color black, legs and antenna ferruginous. Body subrhomboid; almost without constriction between pronotum and elytron; in profile dorsally flat, towards apex convex. Rostrum in apical half dorsally flattened, slightly widened, rugose-punctate; basal half markedly swollen in profile, narrow in dorsal aspect; with indistinct median ridge, densely punctate; dorsolaterally with pair of wide furrows containing erect narrow scales. Pronotum subglabrous, punctate, punctures becoming larger and denser towards apex. Elytra densely punctate; strial punctures slightly larger than minute punctures on intervals; striae impressed as fine lines. Anteroventral ridge of femora terminating with tooth in apical third; tooth largest in metafemur. Metafemur laterally markedly flattened; dorsally with row of silvery scales; posteroventral ridge indistinct, at middle with denticle; dorsoposterior edge weakly denticulate; subapically with stridulatory patch. Aedeagus (Fig. 31b). Body with sides subparallel, extended dorsad; profile of body subtriangular; apex subtruncate, subglabrous; transfer-apparatus complex, symmetrical; ductus ejaculatorius with bulbus. Intraspecific variation. No female specimen available.
