Ocellar setae pair 1 is absent, pair 2 is on either side of the anterior ocellus, and pair 3 is long and between the posterior ocelli. The posteroangular setae are 0.10 to 0.11mm long, and there are usually 3 pairs of posteromarginal setae. Forewing has 3 distal setae, and the abdomen lacks accessory sternal setae. Tergite 8 has a complete comb with teeth as much as 5 times as long as their distance apart. Tergite 9 has 4 pores. Males have glandular areas on sternites 3 to 7. The glandular area is transverse, and elongate-oval on sternite 3, and more circular on the remaining sternites (O'Neill and Bigelow, 1964).
