Diagnostic description.

Holotype, male (Fig. 4a). Length 2.60 mm. Color of legs and head ferruginous, remainder black. Body elongate; in dorsal aspect with marked constriction between pronotum and elytron; with distinct constriction in profile. Rostrum coarsely rugose-punctate, with median ridge and pair of irregular submedian ridges; epistome with indistinct, transverse, subangulate ridge. Pronotum anterolaterally angularly projecting; with distinct subapical constriction; disk scabrous, punctures each with one erect seta; interspaces microreticulate; with median ridge. Elytra with striae deeply impressed, each with row of suberect bristles; intervals irregularly costate, almost tuberculate, nude, weakly microreticulate; interval 7 swollen subapically, laterally weakly projecting. Femora edentate. Metafemur subapically with stridulatory patch and transverse ridge. Abdominal ventrite 5 flat, densely punctate, setose. Penis (Fig. 4b) in profile markedly curved; in dorsal aspect body slender, sides subparallel; apex with median, subtriangular extension; transfer apparatus flagelliform, 1.2 × as long as body; apodemes 2.2 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.23-2.75 mm. Color of sutural interval rarely ferruginous, usually black. Female rostrum dorsally with pairs of lateral and submedian furrows; epistome simple. Elytral apex with interval 7 and sutural interval more or less distinctly projecting. Penis with flagelliform transfer apparatus 1.2-1.5 × longer than body.
