Pronotum with marked subapical constriction, with sparse suberect yellowish scales; disk subglabrous, with few minute punctures; subapically with sparse course punctures. Elytra with striae 1–3 marked by fine hairlines and minute punctures, striae 4–6 marked by minute punctures only; subbasally with few yellowish scales; laterally subglabrous. Femora edentate; anteroventral ridges simple; anterior surface coarsely punctate, especially towards apex, with subrecumbent narrow yellowish scales.

Penis (Fig. 37b) with sides of body subparallel; apex with sparse setae, medially with small angulate extension; apodemes 2.4 × as long as body of penis; transfer apparatus with narrow lyriform frame; ductus ejaculatorius with indistinct bulbus.
