Diagnosis. This species is similar to Y. japonica Moriuti and Y. amoenella (Christoph) in appearance, but can be distinguished by the forewing having a thin longitudinal median dark brown strip on the distal half (Fig. 4), the valva broadest at the apex in the male genitalia (Fig. 105), and the ductus bursae entirely sclerotized in the female genitalia (Fig. 155). In Y. japonica Moriuti and Y. amoenella (Christoph), the forewing lacks a longitudinal median dark brown strip on the distal half, the male valva is broadest before the apex, and the female ductus bursae is membranous.
