Antennal segment 1 is pale yellow, 2 is slightly darker, 3 is pale, but shaded distally with brown, as is the basal half of segment 4. Antennal segment 5 is yellow basally and brown distally, segments 6 and 7 are brown. The head is broader than long, and ocellar setae pair 3 is long and outside of the ocellar triangle. Antennae are 7 segmented with segments 3 and 4 slender and strongly constricting distally. The postocular setae are somewhat long. The pronotum is transversely reticulate, with 3 pairs of posteromarginal setae. The forevein on the forewings has 2 distal setae. There are 4 lateral setae on tergite 2 and a complete posteromarginal comb on tergite 8. Tergite 9 has 2 pairs of sensilla, and the pleurotergites lack accessory setae (Nakahara 1994).
