Holotype, male (Fig. 59a). Length 2.03 mm. Color black; legs ferruginous; antenna light ferruginous. Body subovate, in dorsal aspect with marked constriction between pronotum and elytron; in profile almost evenly convex. Rostrum dorsally scabrous, basally with indistinct median ridge and pair of sublateral ridges; epistome forming angulate ridge and small median denticle. Pronotum densely punctate with ovate punctures, medially subglabrous; at middle with pair of transverse squamose patches; scales cream-colored, subtriangular. Elytra with striae marked by small punctures; interval 4 at middle with cluster of few cream-colored recumbent
scales
. Meso- and metafemur with anteroventral ridge simple. Meso- and metatibia in basal half widened, subapically narrowed. Metafemur with denticulate dorsoposterior edge, subapically without stridulatory patch. Aedeagus (Fig. 59b) with sides of body subparallel, apex rounded; transfer apparatus flagelliform; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.60-2.03 mm.
