Distribution. China (Beijing, Gansu, Henan, Ningxia, Shaanxi, Shanxi), Japan, Korea, Russia, Asia Minor, Mideast Asia, Europe.
Diagnosis. This species is allied to Y. albula sp. nov. in appearance and in the male genitalia, but can be distinguished by the absence of the strips along the veins of the forewing, and the relatively long saccus that is about 2/3 length of the socius (Fig. 114); in Y. albula sp. nov., the forewing has grayish brown or ocherous brown strips along the veins (Fig. 15), and the male saccus is 1/3 length of the socius (Fig. 115). Ypsolopha parenthesella is also related to Y. leuconotella (Snellen) in the female genitalia, but can be separated by the relatively short ductus bursae that is 1.25 times length of the corpus bursae, and the long ovate corpus bursae (Fig. 164); in Y. leuconotella (Snellen), the ductus bursae is 1.5 times length of the corpus bursae and the corpus bursae is triangular (Fig. 159).
Remarks. This species is highly variable in colour, markings and venation of the forewing. The ground colour varies from gray to ocherous brown. In most individuals, there is a white strip extending from basal 1/4 to 3/4 of the cell, but in some other individuals there is a black strip extending from the base to the apex of the cell; the number of the black dots along costa varies from four to about sixteen; the veins R4 and R5 are separated or stalked, but in some individuals R3 is stalked with R4. In spite of these differences among individuals, the black dot at the lower angle of the cell is steady in all of the examined specimens.
