( Figs 40 View FIGURES 40 – 47 , 89 View FIGURES 86 – 91 , 140 View FIGURES 135 – 140 , 185 View FIGURES 182 – 187 )

Type material. Holotype: ♂, China, Ningshan County (33 ° 26 ′ N, 108 ° 26 ′ E), Shaanxi Province, 2300 m, 8.viii. 1987, coll. Houhun Li, genitalia slide No. JQ07104. Paratypes: 1 ♀, Neixiang County (33 °02′ N, 113 ° 50 ′ E), Henan Province, 1350 m, 13.vii. 1998, coll. Houhun Li; 1 ♀, Lushi County (34 °04′ N, 113 °02′ E), Henan Province, 1700 m, 20.vii. 2001, coll. Dandan Zhang.

Diagnosis. The new species is characterized by the ocherous yellow forewing with a white streak along basal half of the costa. It is similar to Y. saitoi Moriuti   , but differs in the forewing having a black dot at middle of the fold ( Fig. 40 View FIGURES 40 – 47 ), the subulate uncus in the male genitalia ( Fig. 140 View FIGURES 135 – 140 ), and the U-shaped lamella postvaginalis in the female genitalia ( Fig. 185 View FIGURES 182 – 187 ). More discussion can be found under Y. saitoi Moriuti.  

Description. Adult ( Fig. 40 View FIGURES 40 – 47 ): Wing expanse 22.0 mm. Vertex rough, yellowish white; face white, yellowish brown around eyes. Antenna white, yellowish on scape, ringed with golden on each flagellomere. Labial palpus white except second segment pale yellowish brown on dorsal side; tuft of second segment triangular, slightly longer than labial palpus; third segment half length of second. Thorax yellowish white. Tegula yellowish brown. Forewing with CuA 1 and CuA 2 separated ( Fig. 89 View FIGURES 86 – 91 ); pale ocherous yellow, with green metallic luster, deep gray at apex; costa brown on basal 1 / 4, with a white medially widened streak along basal 1 / 2; fold with a black dot at middle; yellow mixed with pale brown between fold and dorsum, forming a broad dorsal band; cilia pale yellow, brown-tipped. Hindwing grayish white, darkened to grayish brown toward apex; cilia pale yellow. Fore- and midlegs brown, white mixed with brown on ventral side; hindleg white, scattered with brown on outer side, ringed with white on each tarsomere.

Male genitalia ( Fig. 140 View FIGURES 135 – 140 ): Uncus small subulate. Socius slender, tapering to pointed apex. Ventral plate of gnathos broadly tongue-shaped. Valva ovate, setose along basal half of ventral margin. Saccus about 3 / 5 length of socius. Anellus about a quarter length of phallus, densely spinous on distal half. Phallus as long as valva, curved slightly at middle; coecum 1 / 5 length of phallus; cornuti about half length of phallus, composed of two rows of microspines.

Female genitalia ( Fig. 185 View FIGURES 182 – 187 ): Intersegmental membrane between papilla analis and 8 th abdominal segment 1 / 2 length of abdomen. Apophyses posteriores about twice length of apophyses anteriores. Lamella postvaginalis Ushaped. Antrum weakly sclerotized, parallel-sided. Ductus bursae nearly as long as corpus bursae, broadened gradually from inception of ductus seminalis to corpus bursae. Corpus bursae extremely large, ovate; signum a quarter length of corpus bursae, granulous around, ridged at anterior 1 / 3.

Distribution. China (Henan, Shaanxi).

Etymology. The specific epithet is derived from the Latin umbrinus, meaning ocherous yellow, referring to the colour of the forewing.
