(Figs 48, 97, 148, 192)
Type material. Holotype: ♂, China, Wen County (32°58′ N, 104°41′ E), Gansu Province, 860 m, 13.vii.2005, coll. Haili Yu, slide Nos. JQ07303, JQ07303W. Paratypes: 4 ♂♂, Tianshui (34°37′ N, 105°42′ E), Gansu Province, 11−13.viii.1988, coll. Xingyu Wu; 2 ♂♂, 1 ♀, Kang County (33°20′ N, 105°36′ E), Gansu Province, 800 m, 6−7.vi.1995, coll. Aisihaer Mamati.
Diagnosis. This species is characterized by having a golden yellow forewing (Fig. 48). It is similar to Y. triangula sp. nov., but differs in the forewing without conspicuous golden streak below the costa (Fig. 48), the ovate valva in the male genitalia (Fig. 148), and the V-shaped lamella postvaginalis in the female genitalia (Fig. 192). In Y. triangula sp. nov., the forewing has a golden streak below the costa (Fig. 47), the male valva is triangular (Fig. 147), and the trapezoid female postvaginalis bears a V-shaped emargination at middle on the posterior margin (Fig. 191).
Description. Adult (Fig. 48): Wing expanse 17.0−19.0 mm. Vertex yellow; face white, yellow around eyes. Antenna white, scape yellow dorsally, flagellomere ringed with dark brown. Labial palpus white, yellow on outer surface of second segment; tuft of second segment broad triangular, shorter than labial palpus; third segment less than half length of second. Thorax white, with a longitudinal pale yellow strip medially. Tegula yellow. Forewing with CuA1 and CuA2 nearly connate (Fig. 97); golden yellow, pale gray on costal 2/3, ocherous yellow on basal 3/4 of fold; white streak extending from base of dorsum near fold to 3/4 of fold, gradually narrowed and becoming faint; cilia yellow. Hindwing pale brown, darkened to grayish brown toward apex; cilia yellowish white. Legs white, yellow on femora, mixed with brown on inner side of tibiae and tarsi, grayish brown on outer side of tibia and tarsus of foreleg. Abdomen pale brown on dorsal side, yellowish white on ventral side.
Male genitalia (Fig. 148): Uncus mastoid. Socius slender, point apically. Ventral plate of gnathos nearly rounded, densely spinous. Valva ovate, concave near base on ventral margin. Saccus 2/3 length of socius, basal 1/4 narrowed, distal 3/4 parallel-sided, rounded at apex. Anellus a quarter length of phallus. Phallus 1.2 times length of valva, nearly straight; coecum 1/4 length of phallus; cornuti a quarter length of phallus, composed of two rows of microspines.
Female genitalia (Fig. 192): Intersegmental membrane between papilla analis and 8th abdominal segment 1/2 length of abdomen. Apophyses posteriores about twice length of apophyses anteriores. Lamella postvaginalis Vshaped. Antrum short, parallel-sided. Ductus bursae longer than corpus bursae, thickened from inception of ductus seminalis to corpus bursae. Corpus bursae rounded; signum about 2/5 length of corpus bursae, granulous around, ridged at anterior 1/4, serrate along margins, narrowed posteriorly.
Distribution. China (Gansu).
Etymology. The specific epithet is derived from the Latin aureus, meaning golden yellow, referring to the golden yellow forewing.
