Diagnostic description
Holotype, male (Fig. 44a). Length 2.06 mm. Color of antennae light ferruginous, remainder dark ferruginous to black. Body in dorsal aspect with marked constriction between pronotum and elytron; with distinct constriction in profile. Rostrum dorsally dull, rugulose; with median ridge and pair of indistinct submedian ridges, intervening furrows punctate, sparsely squamose with small suberect scales; epistome simple. Pronotum anterolaterally very weakly angularly projecting; with distinct subapical constriction; disk coarsely punctate, each puncture containing minute scale; interspaces dull, microreticulate; indistinct median ridge subglabrous. Elytra with striae deeply impressed, each with row of minute transparent scales; intervals costate to subcarinate, microreticulate; interval 7 swollen subapically, laterally projecting. Profemur edentate, meso- and metafemur ventrally with denticle. Metafemur subapically with stridulatory patch and transverse rows of denticles. Abdominal ventrite 5 with shallow impression. Penis (Fig. 44b) with body in profile markedly curved ventrad; basal half flattened, in dorsal aspect sides subparallel; towards apex slightly widened; apex with median, subtriangular extension; transfer apparatus flagelliform, ca. 1.3 × as long as body; apodemes 2.2 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.96–2.40 mm. Color of body black or ferruginous. Female rostrum dorsally subglabrous, with pairs of lateral and submedian furrows; epistome simple.
