Type locality: China (Xinjiang). Description. Adult ( Fig. 29 ): Wing expanse 13.5−14.0 mm. Vertex white mixed with pale brown; face white. Antenna with scape grayish on dorsal surface, pale yellowish brown on ventral surface; grayish white ringed with dark brown on each flagellomere. Labial palpus white, mottled brown, grayish white on dorsal side of second and third segments; tuft of second segment triangular, slightly shorter than labial palpus; third segment a little shorter than second. Thorax white scattered with grayish black scales. Tegula brown mixed with gray. Forewing with M3 and CuA1 connate ( Fig. 79 ); yellowish white, scattered with pale yellowish brown scales; costa with about 11 dots or strigulae; cell with irregular dark brown patch at 1/3, 2/3 and end respectively, extending cross fold; narrow dark brown fascia extending obliquely from apex to tornus; brown spot above tornus; cilia white mixed with dark brown. Hindwing and cilia pale grayish brown. Fore- and midlegs dark brown mixed with grayish white except tarsi grayish white mixed with brown on ventral side; hindleg white, mixed with pale gray on outer surface. Abdomen grayish brown on dorsal surface, grayish white on ventral surface. Male genitalia ( Fig. 129 ): Uncus degenerate. Socius slender, ending in point. Ventral plate of gnathos long ovate. Valva ovate, protruded at 2/3 on dorsal margin, ventral margin with a row of fine spines extending from near base to distal 1/4. Saccus about 2/3 length of socius, slightly pointed at apex. Anellus about 1/5 length of phallus, densely spinous in distal half. Phallus extremely slender, about 1.5 times length of valva; coecum about 1/7 length of phallus; cornuti composed of two slender spines, about 3/5 length of phallus. Female genitalia ( Fig. 175 ): Intersegmental membrane between papilla analis and 8th abdominal segment 3/5 length of abdomen. Apophyses posteriores about 2.5 times length of apophyses anteriores. Lamella postvaginalis Y-shaped. Antrum somewhat cup-shaped. Ductus bursae extremely slender, longer than corpus bursae. Corpus bursae ovate; signum about 3/10 length of corpus bursae, ridged at anterior 1/3 and near posterior end respectively. Material examined: Holotype ♂, Tuomurji, Xinjiang Uygur Autonomous Region, 4.vii.1977 , coll. CJ Li ( IZCAS ) (examined). Additional material. 3 ♂♂, 1 ♀, Xunhua County ( 30°50′ N , 102°28′ E ), Qinghai Province, 2240 m , 15.vii.1995 , coll. Houhun Li & Shuxia Wang, genitalia slide No. JQ07278 ♂. Diagnosis. This species is similar to Y. curatorella Baraniak, 2005 externally, but can be distinguished by the longer phallus that is 1.5 times length of the valva in the male genitalia ( Fig. 129 ), and the Y-shaped lamella postvaginalis in the female genitalia ( Fig. 175 ). In Y. curatorella Baraniak , the phallus is slightly shorter than the valva and the lamella postvaginalis comprizes a pair of sclerotized longitudinal bands (Baraniak 2005: Figs 7, 9 ). Distribution. China (Qinghai, Xinjiang). Remarks. The female of this species is described for the first time.
