Trochanters and femora dark brown, femora with silver pollinosity and shining black ventrally (f3 posteriorly as well), knees yellowish brown, tibiae and tarsal segments pale brown, last segment darker. Ventroapical row of 2–10 short, weak spines on first four femora; 4–8 stronger, black spines on 3rd femur. Subapical (distal) spines on first four tibiae present. 1–2 stronger, erect anteromedial hairs on 3rd tibia. Hind trochanter with 2–3 longer white hairs on ventral side. Pulvilli slightly shorter than last tarsal segment.
Wing. Fourth costal section 0.5–0.7 times as long as third costal section. Cross-vein R-M between 1/4 and 1/2 of discal cell. Pterostigma fully coloured. One minute dark hair on tegula.
