Material examined. 2 ♂♂, 2 ♀♀, Mt. Xinglong, Yuzhong County (35°53′ N, 104°06′ E), Gansu Province, 2120−2230 m, 30.vii −1.viii.1993, coll. Houhun Li; 19 ♂♂, 6 ♀♀, Mt.

Shulian Hao.

Host plants. Rosaceae : Malus Mill. , Pyrus communis Linn. , Prunus domestica Linn. ; Crataegus Linn. Cotoneaster Medik. , Sorbus aucuparia Linn. ( Zagulajev 1989; Agassiz 1996; Kozhevnikova 2005; Gershenson & Kozhevnikova 2013).

Distribution. China (Gansu, Henan, Sichuan, Yunnan), Russia, Mideast Asia, Asia Minor, Europe.

Diagnosis. This species is similar to Y. acerella Ponomarenko, Sohn et Zinchenko in the forewing having many erect scales, but can be easily distinguished by having white and brown strips along the veins, which are absent in the latter species. Ypsolopha scabrella is similar to Y. horridella (Treitschke) in the male genitalia, but differs in the saccus as long as the socius and sharp at the apex ( Fig. 118 ), which is 3/4 length of the socius and truncate at the apex in the latter species ( Fig. 121 ). Ypsolopha scabrella is also similar to Y. amoenella (Christoph) in the female genitalia, but can be separated by the signum triangular posteriorly ( Fig. 166 ), which is trapezoid posteriorly in the latter species ( Fig. 157 ).
