Body subovate; in dorsal aspect and in profile with very weak constriction between pronotum and elytron. Rostrum dorsally with median carina and pair of submedian ridges; intervening furrows with rows of subrecumbent yellowish scales; epistome indistinct, somewhat subglabrous, sparsely setose. Pronotum with disk densely punctate; interspaces between punctures subglabrous, subequal to punctures´ diameter; each puncture with fine, recumbent seta; median line impunctate. Elytra irregularly punctate with small punctures; interspaces subglabrous; some striae marked by fine hairlines. Femora dentate with acute tooth; anterior surface coarsely punctate, each puncture with narrow recumbent scale. Metafemur subapically with stridulatory patch. Metatibia clavate, in apical 1/2 widened, in apical 1/3 ventrally with brush of long setae. Metaventrite medially with short median carina. Abdominal ventrites 1–2 concave, sublaterally covered with erect plumose scales; ventrite 5 at middle with shallow concavity, sublaterally with patches of erect scales. Penis (Fig. 59b) with body differentiated into lateral struts and sinuate inner frame, apex subangulate; apodemes 2.1 × as long as body of penis; transfer apparatus complex; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.74–2.88 mm. Female rostrum dorsally subglabrous, with submedian and sublateral rows of punctures. Female metatibia apically less swollen, without brush of long setae.
