Diagnostic description
Holotype, male (Fig. 85a). Length 3.14 mm. Color of antennae and legs ferruginous; remainder black. Body elongate; in dorsal aspect with distinct constriction between pronotum and elytron; in profile dorsally flat. Rostrum dorsally with median ridge and pair of submedian ridges; intervening furrows with rows of erect subclavate scales; epistome short, with median denticle, laterally with two denticles on the right and with one denticle on the left of rostral apex. Pronotum with disk subquadrate, anteriorly forming angulation, before converging to weak subapical constriction; densely coarsely punctate; interspaces between punctures subglabrous; in anterior 1/2 with erect subclavate scales; median line weakly costate, impunctate. Elytra densely irregularly punctate; along basal margin and humeri with punctation more densely; striae marked by fine hairlines; apex subtruncate; apex and base with sparse scales. Foreleg relatively long. Femora with small acute tooth; anteroventral ridges of meso- and metafemur weakly crenate; anterior surface coarsely punctate, reticulate, each puncture with long subclavate scale. Metafemur subapically with stridulatory patch. Dorsal edge of tibiae serrate. Abdominal ventrites 1–2 concave, microreticulate, with sparse punctures bearing erect elongate scales; ventrite 5 flat, coarsely punctate, with erect scales. Penis (Fig. 85b) with sides of body subparallel, converging to slightly spatulate, sparsely setose apex; apodemes 2.1 × as long as body of penis; transfer apparatus spiniform, 0.6 × as long as body of penis; ductus ejaculatorius with indistinct bulbus. Intraspecific variation. Length 2.20–3.14 mm. Female rostrum more slender, dorsal ridges less distinct, sometimes punctate-reticulate, epistome indistinct. Female foreleg shorter.
