Type material. Holotype: ♂, China, Xiaowutai (39°57′ N, 115°02′ E), Yu County, Hebei Province, 1200 m, 22.viii.2005, coll. Yunli Xiao, genitalia slide No. JQ07362. Paratypes: 1 ♀, Mt. Jinge, Chicheng County (40°55′ N, 115°50′ E), Hebei Province, 850 m, 20.vii.2001, coll. Yanli Du & Shulian Hao; 1 ♀, Chifeng (42°17′ N, 118°58′ E), Inner Mongolia Autonomous Region, 590 m, 3.viii.1997, coll. Houhun Li; 2 ♂♂, Horinger County (40°23′ N, 111°48′ E), Inner Mongolia Autonomous Region, 1400−1800 m, 12−13.viii.2007, coll. Houhun Li et al.
Diagnosis. This species is similar to Y. colleaguella Baraniak, 2007 in facies, but can be separated easily by the extremely long saccus about twice length of the socius in the male genitalia (Fig. 127), and the signum with two conspicuous ridges in the female genitalia (Fig. 174). In Y. colleaguella Baraniak, the male saccus is shorter than the socius, and the female signum has one ridge (Baraniak 2007: Figs 3, 7).
Description. Adult (Fig. 27): Wing expanse 19.5−21.0 mm. Head white, scattered with pale yellowish brown. Antenna white, scape mixed with pale brown on dorsal side, flagellum ringed with dark brown except at base. Labial palpus white, mixed with pale brown on outer surface of second and third segments; tuft of second segment rectangular, puffed; third segment shorter than second. Thorax white, with three longitudinal pale gray strips. Tegula pale yellowish brown, mixed with brown. Wing venation as illustrated (Fig. 77). Forewing white mixed with brown on anterior 2/5, pale yellowish brown mixed with brown on posterior 3/5, darkened along boundary, scattered with conspicuous dark scales throughout; costa brown, tinged with pale yellowish brown; dark brown dot placed at middle below fold; cilia white mixed with dark brown. Hindwing gray, cilia slightly brownish. Foreleg grayish brown mixed with white; mid- and hindlegs white, sprinkled with brown on outer surface.
Male genitalia (Fig. 127): Uncus triangular. Socius short, blunt at apex. Ventral plate of gnathos quadrate. Valva oblong, narrowed slightly at base. Saccus extremely long, twice length of socius, narrowed at base, slightly broadened to rounded apex. Anellus slender, about a quarter length of phallus. Phallus extremely slender, about twice length of valva; coecum about 1/6 length of phallus, inception of ductus ejacuiatorius far from base of phallus; cornuti inconspicuous.
Female genitalia (Fig. 174): Intersegmental membrane between papilla analis and 8th abdominal segment 2/5 length of abdomen. Apophyses posteriores about 1.5 times length of apophyses anteriores. Lamella postvaginalis Y-shaped. Antrum slightly cup-shaped. Ductus bursae narrow, about twice length of corpus bursae, twisted near corpus bursae. Corpus bursae long ovate; signum 2/5 length of corpus bursae, granulous around, ridged at posterior 1/6 and at middle respectively.
Distribution. China (Hebei, Inner Mongolia).
Etymology. The specific epithet is derived from the Latin allochrous, meaning different in colour, referring to the anterior 2/5 and posterior 3/5 of the forewing differently coloured.
