Diagnostic description
Holotype, male (Fig. 46a). Length 2.19 mm. Color black; antenna and tarsi ferruginous. Body subovate; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Eyes large. Rostrum basally with median and pair of submedian ridges; median and lateral pairs of longitudinal furrows each with row of overlapping almond-shaped white scales. Pronotum densely punctate; anterolaterally with scattered white scales. Elytra with striae distinct; intervals flat, subglabrous. Profemur edentate, mesofemur with small blunt tooth, metafemur with small acute tooth. Mesofemur and metafemur dorsally sparsely squamose with white scales. Metafemur subapically with stridulatory patch. Metatibia subapically ventrally concave, without brush of long setae; uncus hook-like extended, curved ventrobasad. Aedeagus (Fig. 46b) with apodemes 2.0 X as long as body; sides of body in basal half subparallel; apex extended, pointed, markedly curved ventrad; transfer apparatus flagelliform, longer than body of aedeagus; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.18–2.30 mm. Female rostrum dorsally in apical half subglabrous, sparsely punctate, basally with pair of lateral furrows containing row of scales. Female metatibia apically simple, with simple uncus and minute premucro.
