Diagnostic description
Holotype, male (Fig. 58a). Length 2.45 mm. Color black with bronze lustre, antenna and tarsi ferruginous. Body subovate; in dorsal aspect and in profile with weak constriction between pronotum and elytron. Rostrum dorsally with median and pair of submedian ridges; sparsely squamose with slender subrecumbent scales. Pronotum relatively small; disk sparsely punctate; laterally with sparse, almond-shaped, cream-colored scales. Elytra with striae distinct; intervals flat, subglabrous; interval 2 basally with patch of almond-shaped, cream-colored scales. Femora ventrally with minute denticle. Meso- and metafemur especially dorsally squamose with cream-colored scales; metafemur subapically with stridulatory patch. Meso- and metatibia in apical half with regular row of setae, near uncus with small brush of long setae. Aedeagus (Fig. 58b) apically subtruncate, with dense fringe of setae; subapically sides with pair of membranous protrusions; orifice and body with complex sclerites; transfer apparatus symmetrical; ductus ejaculatorius with bulbus. Intraspecific variation. Length 2.16–2.45 mm. Female rostrum dorsally punctate and sparsely setose, in basal 1/3 coarsely punctate-rugose.
