Diagnosis. Adult ( Fig. 31 ) with wingspan 18.0−23.0 mm. This species resembles E. marginans (Li et Zheng, 1998) in appearance. Encolapta epichthonia can be separated by the large body size, in the male genitalia by the valva not protruded at base on the ventral margin, and the aedeagus rounded at apex ( Fig. 45 ), and in the female genitalia by the papillae anales obviouly narrowed posteriorly ( Fig. 56 ). In E. marginans , the body size is much smaller (wingspan 11.0−16.0 mm); the valva is roundly protruded at base on the ventral margin and the aedeagus is truncate at apex in the male genitalia ( Fig. 44 ); and the papillae anales are quadrate in the female genitalia ( Fig. 55 ).

Distribution. China (Hebei, Henan, Jiangsu, Shaanxi, Shandong, Shanxi, Taiwan, Tianjin, Zhejiang).
