Diagnostic description
Holotype, male (Fig. 11a). Length 2.55 mm. Color ferruginous; dorsal surface of head and pronotum black. Body subovate; in dorsal aspect with distinct constriction between pronotum and elytron; in profile with weak constriction. Rostrum densely punctate-reticulate, without longitudinal furrows or ridges. Eyes large, approximate. Pronotum coarsely punctate-reticulate. Elytra densely striate-punctate; striae deeply impressed; intervals each with dense row of deeply impressed punctures, similar to striae; interspaces costate, subglabrous. Femora edentate. Metafemur subapically with stridulatory patch. Aedeagus (Fig. 11b) apically subangulate, subglabrous; transfer apparatus spiniform, long, subequal to body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.52–2.64 mm. Female rostrum dorsally in apical half with punctures usually isolated.
