Legs with dense setae, without spots. Pretarsal claws brown, with basal dilation.

Forewing long and narrow, most of crossveins brown. Pterostigma indistinct. Costal area with 20–26 crossveins; 13–14 radial crossvein present. 1st rs-psm crossvein located at 2/3 of im; im triangular; m1 smaller than m2; 10 crossveins present between Psm and Psc. c1 smaller than c2, dcc opened. A1 forked, A2 and A3 simple. Three series of gradate veins brown, number of gradates: 7–9/4–5/7–9.

Hindwing narrow, with black suffusion on apical posterior margin. Pterostigma indistinct. Costal area with 18–20 crossveins; 13–14 radial crossveins and 9–10 psm-psc crossveins present. Three series of gradate veins, number of gradates: 8–10/4–6/7–8.

Abdomen with dense setae. Tergum VII and sternum VII subquadrate in lateral view; tergum VIII obviously shorter than tergum VII; sternum VIII fused with sternum IX, slightly exceeded apex of ectoproct; tergum IX fused with ectoproct. Callus cerci ovoid. Gonarcus arcuate, lateral arms narrow at base and wide at tip; entoprocessus sickle-shaped, wide at base and pointed at tip; arcessus curved at middle.
