( Figs 36 View FIGURES 33 – 39 , 136 View FIGURES 135 – 140 , 182 View FIGURES 182 – 187 )

Type material. Holotype: ♂, China: Mt. Qinling (34 ° 14 ′ N, 106 ° 54 ′ E), Shaanxi Province, 18–27.viii. 2003, coll. Min Wang and Guohua Huang, genitalia slide no. JQ 10008. Paratype: 1 ♀, same data as for holotype.

Diagnosis. This species is similar to Y. strigosa (Butler)   in both facies and female genitalia, but differs in the forewing with a well-defined white streak, and the ductus bursae sclerotized on the anterior half and not dilated near the corpus bursae. In Y. strigosa (Butler)   , the ill-defined streak on the forewing is yellowish white, the female ductus bursae is membranous and dilated near the corpus bursae.

Description. Adult ( Fig. 36 View FIGURES 33 – 39 ): Wing expanse 21.0–22.5 mm. Vertex rough, grayish brown; face smooth, grayish white. Antenna light grayish brown, with pale rings on flagellomere. Labial palpus grayish brown, white on inner surface of second segment; tuft on second segment narrow triangular, twice length of labial palpus; third segment extremely short. Thorax and tegula deep gray. Forewing brown; well-defined white streak extending from base to apex below costa, mixed with brown on distal 1 / 4, about 1 / 3 as wide as wing, slightly widened medially; cell with a black dot at end; cilia brown. Hindwing and cilia yellowish brown. Legs brown except hindleg yellowish white on inner side.

Male genitalia ( Fig. 136 View FIGURES 135 – 140 ): Uncus inconspicuous. Socius slender, parallel-sided, pointed at apex. Ventral plate of gnathos large ovate. Valva broad ovate, protruded at middle along dorsal margin. Saccus 3 / 4 length of socius, parallel-sided and round at apex. Phallus slightly shorter than valva, curved at basal 1 / 3; cornuti composed of two broad spines, half length of phallus.

Female genitalia ( Fig. 182 View FIGURES 182 – 187 ): Intersegmental membrane between papilla analis and 8 th abdominal segment 2 / 3 length of abdomen. Apophyses posteriores 1.6 times length of apophyses anteriores. Lamella postvaginalis Vshaped. Antrum short and parallel-sided. Ductus bursae membranous and granulous on posterior half, sclerotized and smooth on anterior half. Corpus bursae nearly round; signum half length of corpus bursae, granulous around, ridged at anterior 1 / 3.

Distribution. China (Shaanxi).

Etymology. The specific epithet is derived from the Latin prefix par -, meaning similar, and strigosa   , the specific name of another species, referring to their similarity.
