Material examined. 1 ♂, 1 ♀, Neixiang County (33°02′ N, 113°50′ E), Henan Province, 1350 m, 13−15.vii.1998, coll. Houhun Li; 1 ♂, 5 ♀♀, Mt. Baiyun, Luoyang (34°11′ N, 112°27′ E), Henan Province, 1560 m, 23−24.vii.2001, coll. Dandan Zhang; 4 ♂♂, Mt. Baiyun, Song County (34°08′ N, 112°05′ E), Henan Province, 1400 m, 15.viii.2008, coll. Houhun Li et al.; 1 ♂, Wolong (31°29′ N, 103°36′ E), Sichuan Province, 1900 m, 8.viii.2004, coll. Yingdang Ren.

Distribution. China (Henan, Sichuan), Japan, Russia.

Diagnosis. This species is similar to Y. strigosa (Butler) in facies and in the male genitalia, but differs in the forewing having a well-defined sword-shaped snow white streak extending from base to middle of the wing ( Fig. 34 ), the cornuti composed of two rows of small thorns and 1/3 length of the phallus in the male genitalia ( Fig. 134 ). In Y. strigosa (Butler) , the ill-defined streak on the forewing is yellowish white, extending from the base to the apex ( Fig. 35 ), the male cornuti are composed of two rows of microspines and 1/2 length of the phallus ( Fig.135 ). The female genitalia of this species are characterized by having a long sack-shaped corpus bursae ( Fig. 180 ).

Remarks. This species is newly recorded for China.
