Diagnostic description
Holotype, male (Fig. 21a). Length 2.38 mm. Color of antennae, tibiae and tarsi ferruginous; remainder black. Body subovate; in dorsal aspect and in profile with weak constriction between pronotum and elytron. Rostrum dorsally with median and pair of submedian ridges; intervening furrows with sparse rows of piliform scales; epistome short, posteriorly with five denticles. Pronotum with disk densely punctate with small punctures; each puncture containing fine, recumbent seta; interspaces between punctures subglabrous. Elytra with striae marked by rows of small punctures; basal margin costate; sutural interval subbasally swollen, coarsely punctate; other intervals subglabrous; humerus with irregular, coarse punctures. Femora edentate; anteroventral ridge distinct, weakly crenate; anterior surface densely coarsely punctate, each puncture with recumbent piliform scale. Metafemur subapically with stridulatory patch. Abdominal ventrites 1–2 concave, microreticulate, subglabrous; ventrite 5 at middle with subtrapezoid impression, microreticulate, punctate. Penis (Fig. 21b) with subangulate extension, medially weakly rounded, without setae; apodemes 3.0 × as long as body of penis; transfer apparatus flagelliform, 2.5 × longer than body of penis; ductus ejaculatorius with indistinct bulbus. Intraspecific variation. Length 2.38–2.40 mm. Female rostrum more slender; dorsally in apical 1/2 subglabrous, with two submedian rows of punctures, with pair of sublateral furrows.
