Diagnostic description
Holotype, male (Fig. 8a). Length 3.28 mm. Color of legs and head ferruginous, elytra ferruginous with transverse sinuate black band, remainder black. Body elongate; in dorsal aspect with marked constriction between pronotum and elytron; in profile dorsally convex. Rostrum with median and pair of submedian ridges; intervening furrows punctate, each with row of erect setae; epistome simple. Pronotum with subapical constriction; disk densely punctate; punctures partly elongate and / or arranged in confluent rows forming rhombus-like pattern; each puncture containing elongate white scale or seta; medially with glabrous costa. Elytra with striae indistinct; intervals flat; with small, confused punctures; with sparse rows of elongate, recumbent, cream-colored scales; interspaces microreticulate; interval 7 in apical third forming sharp lateral edge; sutural interval at apex swollen, weakly protruding. Anteroventral ridge of femora crenulate, forming blunt tooth. Metafemur subapically with stridulatory patch. Dorsal edge of tibiae subbasally simple, with angulation. Metatibia apically without premucro. Abdominal ventrite 5 flat, coarsely punctate. Penis (Fig. 8b) with sides of body subparallel; apex medially with short median extension rounded; transfer apparatus compact, transfer-processes sickle-shaped, in profile with ventral contour evenly convex; apodemes 2.4 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.88–3.18 mm. Color largely light ferruginous or black except antennae and legs ferruginous. Female rostrum with median and pair of submedian ridges costate, subglabrous.
