Dorsal surface glabrous, ventrally moderately setose, setae distinctly elongate. Color almost completely testaceous, but head black except clypeus, antennae light pale whitish yellow, and pronotum and legs slightly darker (
Fig. 1
A).
Head:
Dorsal surface finely punctate, more punctate on frons; clypeus almost impunctate, sides parallel at base, then weakly convergent to trapezoidal, reflexed apex (
Figs 1
A–B). Frontoclypeal suture obsolete. Antennae with lamellae extremely developed, moderately and densely punctate (

C); first lamella externally with longitudinal row of scattered setae.
Mouthparts:
Mandibles slender, apices upturned and weakly curved externally; last maxillary palpomere as long as preceding 2 together.

Surface moderately and uniformly punctate, smooth along center line, posterior margin with a weak bead at middle. Scutellum totally punctate, punctures moderately large.
Elytra:
Surface distinctly punctate; striae well defined but weakly marked, punctures fine.
