Ventroapical row of 7–8 black, short spines on first four femora; 5–6 spines on 3rd femur (same size). Subapical (distal) spines on first four tibiae missing. 2–3 erect anteromedial hairs on 3rd tibia. Hind trochanter with 2 brown hairs on ventral side (as long as width of f3 at base). Pulvilli distinctly shorter than last tarsal segment.
Wing. Cross-vein R-M at 1/3 of discal cell. Pterostigma fully coloured. Hairs on tegula missing.
Abdomen
. Viewed obliquely from front tergites brownish pollinose (T1 silvery), hind margins with small grey triangles laterally (almost reaching each other on T5), sides completely greyish pollinose. No abdominal hairs. Lateral spines on first tergite dark brown, in a row of 4–5. Postabdomen in dorsal view: T5 1.2 times as long as ST8. Genitalia without dissection: ST8 subshining brown, cerci yellowish, m.a. round, pv directed, occupies 2/3 of width of ST8.
Genitalia. Surstyli symmetric, rounded at tip; epandrium small; ST8 with large m.a. (
