Diagnostic description

Holotype, male (Fig. 1a). Length 3.00 mm. Color of antennae and legs ferruginous; remainder black. Body shape dominated by laterally protruding humeri; in dorsal aspect with marked constriction between pronotum and elytron; in profile dorsally convex. Rostrum in basal 1/2 dorsally with median ridge and pair of submedian ridges; anteriorly coarsely punctate; furrows with rows of erect subclavate scales; epistome with transverse ridge and submedian pair of denticles. Pronotum anteriorly with lateral flanges; disk subquadrate, coarsely punctate; interspaces subglabrous. Elytra with humeri markedly protruding; densely irregularly punctate with small punctures, near base punctures larger; striae indistinct, some marked by hairlines; sutural interval in basal 1/3 swollen, densely irregularly punctate; swollen humeri densely coarsely punctate; subbasally with yellowish almond-shaped scales; subapically with sparse narrow scales. Femora with anteroventral ridge distinct, crenate, in meso- and metafemur ending with denticle; anterior surface punctate-reticulate, each puncture with a scale, dorsally scales erect and subclavate. Metafemur with dorsoposterior edge serrate; subapically with stridulatory patch. Metatibia with posterior surface densely setose in subapical 1/2, with erect scales in basal 1/2. Abdominal ventrites 1–2 concave, subglabrous. Abdominal ventrite 5 flat, densely coarsely punctate. Penis (Fig. 1b) with body differentiated into hyaline lateral flanges and sclerotized inner frame; sides of body weakly diverging; apex with median constriction; apodemes 3.1 × as long as body of penis; transfer apparatus complex, asymmetrical; ductus ejaculatorius without distinct bulbus. Intraspecific variation. Length 2.20–3.00 mm. Female rostrum dorsally flattened, with ridges less distinct; epistome indistinct. Female pronotum without lateral flanges. Female elytra without swollen humeri.
