Antennae are brown with the apices of segment 2 and most of segment 3 yellowish brown. The head is broader than long, and the antennae are 8 segmented. There is a row of 3 or 4 small tubercles cephalad of the anterior ocellus. The pronotum has transverse anastamosing striations and 3 pairs of posteromarginal setae. The mesonotum is completely sculptured, and there are large reticulations medially along the first third of the metanotum. The forevein on the forewing has 3 distal setae, though occasionally 2 or 4 may be present. Abdominal tergite 2 has 4 lateral setae. On tergite 8 there is a posteromarginal comb of microtrichia of irregular length. Tergite 9 has 2 pairs of campaniform sensilla. Accessory setae are present on sternites 2 to 7 in an irregular row. In males, a transversely oval glandular area is present on each of sternites 3 and 4 (Nakahara 1994).
