Diagnosis. This species is characterized by the forewing having several longitudinal rows of ocherous brown scales except at base of the cell. Ypsolopha yangi is similar to Y. horridella (Treitschke) in facies, but differs in the forewing with rounded apex, which is triangularly protruded in the latter species. Ypsolopha yangi is also similar to Y. leuconotella (Snellen) in genitalia, but differs in the socius parallel-sided on the basal 3/ 4 in the male genitalia ( Fig. 120 ), and the ductus bursae sparsely granulous before the inception of the ductus seminalis in the female genitalia ( Fig. 168 ); whereas the male socius is dilated at middle, and the female ductus bursae is granulous throughout in the latter species.

Distribution. China (Beijing, Hebei, Ningxia, Qinghai, Sichuan), Russia (Far East).
