Body small, oval, 2.0 times as long as wide. Head short and broad, 1.7 times as wide as long, length of head almost subequal to length of pronotum on midline. Antennae long, slender, four-segmented, ratio of antennal segments I:II:III:IV=1:2.8:1.9:1.8. Pronotum subtrapezoid, 3.1 times as wide as long, moderately narrowed towards the front, anterior margin narrower than head, lateral margins nearly straight, posterior margin concave, posterior angles feebly rounded. Scutellum longer than pronotum on midline, triangle, and width about 1.4 times of length.
