Diagnostic description
Holotype, male (Fig. 29a). Length 1.70 mm. Color of antenna, tarsi, tibiae, and rostrum ferruginous; head and pronotum black; elytra black, with ferruginous patches near base of intervals 2–4, continued to apex with irregular patches on intervals 1–4 to apex. Body subovate; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Eyes large. Rostrum punctate, without distinct longitudinal ridges; laterally with rows of cream-colored scales. Pronotum densely punctate-reticulate; with few scattered cream-colored scales; each puncture containing one brownish seta. Elytra with striae deeply impressed, intervals costate, with scattered white scales. Femora ventrally edentate, subapically constricted. Tibial uncus simple, curved. Metafemur subapi- cally with stridulatory patch. Aedeagus (Fig. 29b) with sides of body sinuate, converging; apex extended, pointed, curved ventrad; transfer apparatus compact, symmetrical; ductus ejaculatorius basally swollen, without bulbus. Intraspecific variation. Length 1.63–1.86 mm. Ferruginous color of elytra more or less extensive. Female rostrum dorsally subglabrous, laterally punctate. Body of males rather slender, females slightly stouter.
