( Figs 30 View FIGURES 26 – 32 , 80 View FIGURES 80 – 85 , 130 View FIGURES 129 – 134 , 176 View FIGURES 176 – 181 )

Type material. Holotype: ♂, China, Chengcheng County (35°22′ N, 109°57′ E), Shaanxi Province, 1000 m, 10.viii.1993, coll. Houhun Li, genitalia slide No. L94131 View Materials . Paratypes: 1 ♀, same data as for holotype except dated 7.vii.1987; 1 ♀, Mt. Xinglong, Yuzhong County (35°53′ N, 104°06′ E), Gansu Province, 2130 m, 2.viii.1993, coll.

Houhun Li; 2 ♂♂, Tacheng (46°46′ N, 82°59′ E), Xinjiang Uygur Autonomous Region, 20−23.viii.1990, coll. Jinfu Li; 1 ♀, Zepu County (38°12′ N, 77°15′ E), Xinjiang Uygur Autonomous Region, 2.viii.1994, coll. Aisihaer Mamati.

Diagnosis. This species is similar to Y. longifloccosa sp. nov. in both facies and genitalia, but differs in the forewing with M3 and CuA1 separated ( Fig. 80 View FIGURES 80 – 85 ), the relatively long phallus about 1.5 times length of the valva in the male genitalia ( Fig. 130 View FIGURES 129 – 134 ), and the female ductus bursae slightly longer than the corpus bursae in the female genitalia ( Fig. 176 View FIGURES 176 – 181 ). In Y. longifloccosa sp. nov., M3 and CuA1 of the forewing are connate ( Fig. 81 View FIGURES 80 – 85 ), the male phallus is 1.2 times length of the valva ( Fig. 131 View FIGURES 129 – 134 ), and the female ductus bursae is 2.5 times length of the corpus bursae ( Fig. 177 View FIGURES 176 – 181 ).

Description. Adult ( Fig. 30 View FIGURES 26 – 32 ). Wing expanse 16.0−17.0 mm. Head pale brown, white mixed with brown around eyes. Antenna grayish brown, ringed with white on each flagellomere. Labial palpus pale grayish brown except basal segment white on ventral surface and second segment white dorsal surface; tuft of second segment slightly longer than labial palpus; third segment longer than second. Thorax and tegula grayish brown. Forewing with M3 and CuA1 separated ( Fig. 80 View FIGURES 80 – 85 ); pale brown, scattered with white and black scales; costa with five dark brown patches alternated with tiny dark brown dots; cell with dark brown patch at 1/3 and 2/3 respectively, the latter larger and edged with a white streak along outer margin, V-shaped dark brown pattern on distal 1/4 of cell directing to base of wing, short white strip situated at lower angle; two dark brown dots at tornus; four dark brown dots along inside of termen; cilia yellowish brown, mixed with dark brown. Hindwing and cilia yellowish brown. Fore- and midlegs grayish black scattered with white, femora grayish white mixed with gray; hindleg yellowish white, gray at base on outer side of femur, grayish black on tarsus and spurs, ringed with white on each tarsomere.

Male genitalia ( Fig. 130 View FIGURES 129 – 134 ): Uncus degenerate. Socius short, widely spaced, slightly pointed at apex. Ventral plate of gnathos broadly tongue-shaped. Valva short and broad, 1.5 times as long as wide. Saccus nearly as long as socius, slender, dilated near apex, slightly pointed at apex. Anellus only 1/10 length of phallus, without conspicuous spines. Phallus slender and straight, about 1.5 times length of valva; coecum about 2/7 length of phallus; cornuti about a quarter length of phallus, composed of two slender spines.

Female genitalia ( Fig. 176 View FIGURES 176 – 181 ): Intersegmental membrane between papilla analis and 8th abdominal segment 2/5 length of abdomen. Apophyses posteriores about twice length of apophyses anteriores. Lamella postvaginalis a sclerotized trapeziform plate. Antrum short, cup-shaped. Ductus bursae slightly longer than corpus bursae. Corpus bursae elongate ovate, granulous; signum about half length of corpus bursae, ridged at near posterior end and at middle respectively.

Distribution. China (Gansu, Shaanxi, Xinjiang).

Etymology. The specific epithet is derived from the Latin brevi-, meaning short, and and the Latin valva, referring to the short and broad valva in the male genitalia.
