The antennae are brown, though segment 3, and the basal portions of segments 4 to 6 are yellow. The head is broader than long, and ocellar setae pair 3 is outside or on the border of the ocellar triangle, and posterolaterad to the anterior ocellus. The antennae are 7 segmented, and on segment 6, the base of the inner sense cone is oval. There are weak striations on the posterior half of the pronotum, and 3 or occasionally 4 pairs of posteromarginal setae. There is 1 pair of anteromedial campaniform sensilla present on the mesonotum. The metanotum is longitudinally striate and sensilla are absent. The forevein on each forewing has 3 distal setae. Abdominal tergite 2 has 4 (occasionally 3) lateral setae, and the posterior margins of tergite 6 and 7 may have some scallop-shaped striations. Tergite 8 has a complete posteromarginal comb, tergite 9 has 2 pairs of campaniform sensilla, and sternites 2 to 7 have accessory setae. Sternite 1 has 3 anteromedial setae. On sternites 3 to 7 on males the glandular areas are transversely oblong (Nakahara 1994).
