Holotype, male (Fig. 57a). Length 1.65 mm. Color of antennae and tarsi ferruginous, remainder black. Body in dorsal aspect with marked constriction between pronotum and elytron; with distinct constriction in profile. Rostrum in basal half with median ridge and pair of submedian ridges, in apical half flat; epistome with transverse, subangulate ridge. Pronotum with indistinct subapical constriction; disk coarsely punctate-rugose, sparsely setose; in basal half with pair of sublateral, curved impressions. Elytra with striae deeply impressed, each with row of short, suberect setae; intervals costate, subglabrous; apex rounded. Meso- and metafemur with small tooth; profemur, simple. Metafemur subapically with stridulatory patch. Abdominal ventrite 5 flat, coarsely punctate. Penis (Fig. 57b) with sides of body subparallel, in apical third rounded to apex, subglabrous; transfer apparatus flagelliform, thin, 3.1 × as long as body; apodemes 2.4 × as long as body; ductus ejaculatorius with indistinct bulbus. Intraspecific variation. Length 1.65–2.01 mm. Coloration dark as in holotype, or partly deep ferruginous, especially along elytral suture. Female rostrum dorsally subglabrous, sparsely punctate, with dorsolateral pair of furrows. Pronotum with impressions in basal half simple or kidney-shaped; disk with or without median ridge. Elytral intervals more or less distinctly costate-carinate. Profemur with or without tooth.
