Diagnostic description

Holotype, male (Fig. 75a). Length 2.24 mm. Color of antennae light ferruginous, pronotum black, remainder dark ferruginous. Body in dorsal aspect subrhomboid, with marked constriction between pronotum and elytron; in profile dorsally convex. Rostrum with median ridge bordered by rows of coarse punctures; with sparse suberect scales; epistome with transverse, subangulate ridge bearing 5 denticles. Pronotum with indistinct subapical constriction; anteriorly with flanges projecting laterally; sides subparallel; disk densely punctate; interspaces subglabrous; each puncture containing small recumbent seta. Elytra with humeri swollen, laterally projecting subangularly, with coarse punctures; striae marked by small punctures, each containing minute seta; intervals flat, subglabrous; elytral apex subtruncate, in apical aspect ventral outline concave. Femora with anteroventral ridge, in meso- and metafemur with denticle. Metafemur subapically with stridulatory patch. Dorsal edge of tibiae subbasally angulate. Abdominal ventrites 1–2 forming common cavity, at middle flat, subglabrous, with sparse erect scales; laterally with distinct rim; abdominal ventrite 5 weakly concave, coarsely punctate, with sparse erect scales. Penis (Fig. 75b) with sides of body subparallel, in apical half with shallow constriction; apex rounded; behind ostium with pair of large sclerites; transfer apparatus digiform, held by frame of two parallel sclerites; apodemes 1.9 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.78–2.36 mm. Body of small specimens more slender, with elytral humeri less distinctly projecting, lateral flanges of pronotum less distinct. Female rostrum slender, dorsally subglabrous, with submedian rows of coarse punctures, sublaterally punctate-rugose; epistome simple. Female elytral humeri less prominent, evenly convex.
