Diagnostic description.
Holotype, male (Fig. 11a). Length 2.65 mm. Color of antennae and legs ferruginous; remainder black. Body subovate; in dorsal aspect with distinct constriction between pronotum and elytron; in profile with weak constriction. Rostrum dorsally with median costa and pair of submedian ridges; intervening furrows each with row of suberect scales; apical 1/3 punctate-rugose, with indistinct epistome. Pronotum with weak subapical constriction; disk densely punctate; interspaces between punctures subglabrous; indistinct lateral edges more densely punctate, median line impunctate. Elytra irregularly punctate; some striae marked by hardly visible hairlines; basal margin bordered by denser punctures; stria 8 along humerus with six large, coarse punctures. Femora edentate; anteroventral ridge of mesofemur and metafemur crenate; anterior surface of metafemur coarsely punctate, each puncture with subrecumbent silvery scale. Metafemur subapically with stridulatory patch. Metatibia near middle with dense, beard-like cluster of long setae; subapically ventral surface subglabrous, lined by setose fringes. Abdominal ventrites 1-2 concave, punctate, with sparse suberect lanceolate scales; ventrite 5 with distinct, round depression, with suberect lanceolate scales. Penis (Fig. 11b) with sides weakly sinuate; apex with median notch, without setae; apodemes 1.7 × as long as body of penis; transfer apparatus complex; ductus ejaculatorius with indistinct bulbus. Intraspecific variation. Length 2.50-2.65 mm.
