Diagnosis. This species is allied to Y. diana (Caradja) superficially, but can be distinguished by having a small black dot at end of the cell (Fig. 51), and the separated CuA1 and CuA2 of the forewing (Fig. 100); in Y. diana (Caradja), there is a triangular black patch at end of the cell, and CuA1 and CuA2 are stalked (Fig. 102). Ypsolopha nemorella is similar to Y. ulingensis Yang and Y. capitalba sp. nov. in the male genitalia, but differs in the triangular uncus and the medially curved phallus (Fig. 151); in the latter two species, the uncus is degenerate and the phallus is nearly straight. Ypsolopha nemorella is also similar to Y. yasudai Moriuti in the female genitalia, but can be separated by the short signum that is 1/3 length of the corpus bursae (Fig. 195), while the signum is 1/2 length of the corpus bursae in the latter species (Fig. 189).
