Adult ( Fig. 6 ): Wing expanse 19.5−22.0 mm. Forewing with R4 and R5 short stalked ( Fig. 57 ).

Material examined. 1 ♂, Shuangyuanfeng, Mt. Xinglong (40°36′ N, 117°29′ E), Hebei Province, 800 m, 17.vii.2011, coll. Houhun Li & Yanpeng Cai; 2 ♂♂, 1 ♀, Mt. Baiyun (34°08′ N, 112°05′ E), Henan Province, 1580 m, 24−25.vii.2002, coll. Xinpu Wang; 1 ♂, Huinan County (42°42′ N, 126°16′ E), Jilin Province, 11.vii.1991; 1 ♀, Laotudingzi, Huanren County (41°15′ N, 125°21′ E), Liaoning Province, 8−9.viii.2009, coll. Weichun Li & Jiayu Liu.

Distribution. China (Hebei, Henan, Jilin, Liaoning), Japan, Korea, Russia.

Diagnosis. This species is characterized by the forewing having a broad black dorsal band and with a dark brown strip at end of the cell ( Fig. 6 ), the cornuti consisting of two long thorns in the male genitalia ( Fig. 107 ), and the ductus bursae granulous throughout and the signum trapezoid posteriorly in the female genitalia ( Fig. 157 ). Ypsolopha amoenella is similar to Y. scabrella (Linnaeus) in the female genitalia, but differs in the signum trapezoid posteriorly, which is triangular posteriorly in the latter species. Ypsolopha amoenella is also similar to Y. japonica Moriuti in genitalia, and the differences between them are stated in detail under the latter species.
