The main differences on the forewing patterns are follows: each line is blackish brown in the new species compared with the black line in E. sinonanlinga ; in the new species the basal line is invisible, but in E. sinonanlinga the basal line is present and arc-shaped; in the new species the subterminal line is closer to the terminal line than E. sinonanlinga ; in the new species the median fascia is brown, but dark orange-brown in E. sinonanlinga .

Hindwing unicolorous, pale blackish brown, discal spot invisible.

Male genitalia ( Figs 14 & 15 ). Uncus rather long and tapering, apically pointed; tegumen narrow, elongated; valva moderately long, broadly rounded apically; costal margin slightly sclerotized; saccus small, tongue-shaped; harpe short, finely dentate. Aedeagus short; vesica without cornuti.
