Host plants. Lonicera xylosteum Linn. , L. carprifolium Linn. ( Gershenson & Kozhevnikova 2013) .

Distribution. China (Henan, Liaoning), Russia, Central Europe.

Diagnosis. This species is allied to Y. triangula sp. nov. in facies, but differs in the forewing having a short white stripe extending obliquely upward from beyond 2/3 of the fold to end of the cell ( Fig. 46 ), which is absent in the latter species. Ypsolopha falcella is similar to Y. varidentella sp. nov. in genitalia, but can be distinguished by the valva protruded dorsally at middle and the straight phallus in the male genitalia ( Fig. 146 ), and the signum 1/2 length of the corpus bursae and ridged at anterior 1/5 ( Fig. 190 ) in the female genitalia. In Y. varidentella sp. nov., the valva is straight dorsally, the phallus is curved at middle in the male genitalia ( Fig. 143 ), and the signum is 2/5 length of the corpus bursae and ridged at anterior 1/ 3 in the female genitalia ( Fig. 188 ).

Remarks. This species is newly recorded for China.
