Holotype, male (Fig. 37a). Length 2.90 mm. Color of head, disk of elytra, legs and antennae ferruginous; remainder black. Body elongate; 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 punctate; epistome with indistinct, transverse, subangulate ridge, at middle with denticle. Pronotum anterolaterally weakly angularly projecting; with distinct subapical constriction; disk coarsely punctate-rugose; punctures each with slender suberect scale; with median ridge. Elytra with striae deeply impressed, each with partly abraded row of slender, suberect scales; intervals tuberculate, almost nude; interval 7 swollen subapically, laterally weakly projecting. Femora edentate. Metafemur subapically with stridulatory patch and transverse row of denticles. Metatibia ventrally with sparse row of long erect setae, apically with uncus and distinct premucro. Abdominal ventrite 5 with shallow median impression, punctate, microreticulate. Penis (Fig. 37b) with body in profile curved, basal half flattened; in dorsal aspect sides subparallel; apex medially weakly extended; transfer apparatus flagelliform, ca. 2.4 × as long as body; apodemes 2.6 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.53–3.00 mm. Color of body black to ferruginous. Female rostrum dorsally with longitudinal furrows; epistome simple. Pronotum with anterolateral knobs blunt, somewhat rounded, or more distinct angularly projecting. Elytral striae with erect scales slightly shorter or longer and, rather dense or sparse depending on state of abrasion. Male metatibia ventrally with fringe of long setae dense, sparse or almost absent. Female abdominal ventrite 5 flat or slightly convex.
