Distribution. China (Heilongjiang, Jilin, Liaoning, Xinjiang), Japan, Korea, Russia.

Diagnosis. This species is similar to Y. varidentella sp. nov. and Y. falcella (Denis et Schiffermüller) externally, but differs from Y. varidentella sp. nov. in the forewing having a small black dot below middle of the fold ( Fig. 45 View FIGURES 40 – 47 ), which is absent in the latter species; differs from Y. falcella by the absence of the short white line at end of the cell, which is present in the latter species. Ypsolopha yasudai is related to Y. nigrofasciata Yang in the male genitalia, but can be separated by the subulate uncus ( Fig. 145 View FIGURES 141 – 146 ), which is triangular in the latter species ( Fig. 137 View FIGURES 135 – 140 ). Ypsolopha yasudai is similar to Y. nemorella (Linnaeus) in the female genitalia, but can be separated by the relatively long signum that is about 1/2 length of the corpus bursae ( Fig. 189 View FIGURES 188 – 193 ), which is 1/3 length of the corpus bursae in the latter species ( Fig. 195 View FIGURES 194 – 197 ).

Remarks. This species is somewhat variable in appearance, viz., the ground colour varying from yellow to pale grayish brown, the area between the fold and the dorsum varying from yellowish white to grayish brown. In spite of these differences, the black dot below middle of the fold, the wing venation, and the genital characters are stable.
