Distribution. China (Gansu, Guizhou, Hebei, Heilongjiang, Henan, Inner Mongolia, Jilin, Liaoning, Sichuan, Tianjin, Xinjiang), Japan, Korea, Russia (Ussuri, Amur).

Diagnosis. This species is similar to Y. bisticta sp. nov. in both facies and genitalia, but can be distinguished by the absence of the black dot at basal 1/5 below the fold on the forewing ( Figs 49 a-b), the relatively shorter saccus which is shorter than the socius and the stout phallus in the male genitalia ( Fig. 149 ), and the lamella postvaginalis with two basally intilted bands in the female genitalia ( Fig. 193 ). In Y. bisticta sp. nov., the forewing has a black dot at basal 1/5 below the fold ( Fig. 52 ), the male saccus is as long as the socius, and the phallus is extremely slender ( Fig. 152 ), and the female lamella postvaginalis is V-shaped ( Fig. 196 ).

Remarks. This species varies in appearance. The ground colour of the forewing varies from pale yellow to ocherous yellow, the costa from ocherous yellow to dark gray, the cell and the area between the fold and the dorsum from white to yellow, and the strips along veins from white to pale yellow. In spite of the differences above, the black dot below middle of the fold and the genital characters are stable.
