Holotype, male (Fig. 103a). Length 1.90 mm. Color of antennae and tarsi ferruginous; legs and head dark ferruginous; remainder black, with slight bronze luster. Body subovate; in dorsal aspect with weak constriction between pronotum and elytron; in profile dorsally convex, with very weak constriction between pronotum and elytron. Rostrum dorsally with shortened median and pair of longer submedian ridges; intervening furrows with sparse rows of scales; epistome short, posteriorly with transverse, subangulate ridge. Pronotum with disk coarsely punctate; interspaces between punctures subglabrous. Elytra with striae marked by minute punctures; basal margin bordered by transverse row of deeper punctures; stria 8 in basal 1/2 with larger punctures, externally bordered by costa; intervals flat, subglabrous; apex ventrally subtruncate. Femora dentate. Anteroventral ridge of meso- and metafemur crenate, ending with blunt tooth. Metafemur dorsally denticulate, subapically with stridulatory patch. Abdominal ventrites 1–2 concave, subglabrous, microreticulate; ventrite 5 with sublateral ridges, at middle with impression basally bound by curved transverse ridge, densely punctate. Penis (Fig. 103b) with sides of body subparallel; apex somewhat asymmetrical, with subtriangular median extension; behind ostium with pair of elongate endophallic sclerites; apodemes 2.7 × as long as body of penis; transfer apparatus small, complex; ductus ejaculatorius with distinct bulbus. Intraspecific variation. Length 1.86–1.90 mm. Female rostrum dorsally flattened; apical 1/2 punctate, basal 1/2 with ridges less distinct; epistome indistinct.
