Host plant. Caragana arborescens Lam. (Zagulajev 1989) .

Distribution. China (Ningxia, Xinjiang), Estonia, Finland, Latvia, Russia.

Diagnosis. This species is similar to Y. fascimaculata sp. nov. in the female genitalia, but can be distinguished by the Y-shaped lamella postvaginalis and the smooth ductus bursae (Fig. 163). In Y. fascimaculata sp. nov., the lamella postvaginalis is V-shaped and the ductus bursae is granulous on the posterior 1/3 (Fig. 165). The male genitalia of this species are characterized by having a stout phallus that is as long as the valva (Fig. 113).

Remarks. This species is newly recorded for China, with the female genitalia described for the first time.
