Diagnostic description

Holotype (Fig. 6a). Length 2.78 mm. Color black; antenna and legs ferruginous. Body subovate, in dorsal aspect and in profile with marked constriction between pronotum and elytron. Rostrum punctate-scabrous, in basal third with median ridge and pair of submedian ridges; in front of antennal insertion with median bifid protrusion; punctures containing upcurved narrow scales; epistome posteriorly with curved ridge bearing 4 denticles. Forehead coarsely punctate-rugose. Pronotum with sides subparallel, anteriorly abruptly rounded to indistinct subapical constriction; irregularly foveate-reticulate; each fovea containing one inconspicuous seta; interspaces forming irregular, mainly longitudinal ridges. Elytra converging from humeri to apex; base bisinuate; striae deeply impressed, with coarse punctures; intervals carinate to costate; with sparse subrecumbent scales; sutural interval prominent, near base markedly swollen. Legs. Femora punctate-rugose, with sparse suberect scales. Tibiae subbasally with dorsal angulation; metatibia subapically with suprauncal angulation. Metaventrite subglabrous except deep median furrow. Abdominal ventrite 1 concave; abdominal ventrite 2 posteriorly transversely costate. Penis (Fig. 6b) with sides of body weakly converging from base to subtruncate apex; in profile ventrally with marked subapical swelling; transfer apparatus short, dentiform; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.92–3.34 mm. Body usually covered with more or less thick soil incrustations removed in holotype. Female body slender. Female rostrum dorsally somewhat flattened, without protrusion; in basal half with median costa and pair of submedian costae; epistome simple.
