Holotype, male (Fig. 66a). Length 1.75 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 with median ridge and pair of submedian ridges, intervening furrows with sparse rows of setae; epistome with transverse, subangulate ridge. Pronotum with subapical constriction; disk coarsely punctate-rugose, sparsely setose; in basal half with pair of sublateral, kidney-shaped impressions; with median ridge. Elytra with striae deeply impressed, each with row of short, suberect setae; intervals costate-carinate, subglabrous; apex subtruncate, weakly rounded. Femora each with small tooth; profemur relatively long. Metafemur subapically with stridulatory patch. Abdominal ventrite 5 flat, coarsely punctate. Penis (Fig. 66b) with sides of body subparallel, in apical third converging; apex subangulate, medially with sparse setae; transfer apparatus flagelliform, relatively thick, 2.6 × as long as body; apodemes 2.5 × as long as body. Intraspecific variation. Length 1.71–1.86 mm. Coloration dark as in holotype, or largely deep ferruginous. Female rostrum dorsally subglabrous, sparsely punctate, with dorsolateral pair of furrows.
