(Figs 40, 89, 140, 185)
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), the subulate uncus in the male genitalia (Fig. 140), and the U-shaped lamella postvaginalis in the female genitalia (Fig. 185). More discussion can be found under Y. saitoi Moriuti.
Description. Adult (Fig. 40): 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 CuA1 and CuA2 separated (Fig. 89); 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): 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): Intersegmental membrane between papilla analis and 8th 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.
