( Figs 22 View FIGURES 19 – 25 , 73 View FIGURES 69 – 74 , 122 View FIGURES 117 – 122 , 169 View FIGURES 164 – 169 )

Type material. Holotype: ♂, China, Yebadan, Tacheng (46°46′ N, 82°59′ E), Xinjiang Uygur Autonomous Region, 17.vii.1997, genitalia slide No. FXM07023. Paratypes: 1 ♂, same data as for holotype (abdomen missing); 1 ♀, Tacheng (46°46′ N, 82°59′ E), Xinjiang Uygur Autonomous Region, 5.vii.1990, coll. Jinfu Li.

Diagnosis. This species is characterized by the socius with distal 1/6 narrowed sharply to a thorn in the male genitalia ( Fig. 122 View FIGURES 117 – 122 ). It is similar to Y. bicostata sp. nov. both externally and internally, but can be distinguished by the forewing having several rows of dark brown scales ( Fig. 22 View FIGURES 19 – 25 ), the male saccus slightly shorter than the socius ( Fig. 122 View FIGURES 117 – 122 ), and the female signum 3/5 length of the corpus bursae ( Fig. 157 View FIGURES 153 – 157 ). In Y. bicostata sp. nov., the forewing lacks rowed dark brown scales ( Fig. 23 View FIGURES 19 – 25 ), the male saccus is just 3/5 length of the socius ( Fig. 123 View FIGURES 123 – 128 ), and the female signum is 1/2 length of the corpus bursae ( Fig. 166 View FIGURES 164 – 169 ).

Description. Adult ( Fig. 22 View FIGURES 19 – 25 ): Wing expanse 18.0−20.0 mm. Head white, dark brown around eyes. Antenna grayish brown, ringed with white on each flagellomere. Labial palpus grayish brown except basal segment white; third segment longer than second. Thorax white. Tegula dark brown. Forewing with R4 and R5 almost connate ( Fig. 73 View FIGURES 69 – 74 ); grayish brown, tinged with grayish white on distal 1/3, with several longitudinal rows of dark brown scales; costa dark brown on basal 3/4; cell with curved black strip on distal half, with a small black dot at lower angle; yellowish white line extending from end of cell to apex; dorsal band dark brown, with curved yellowish white line along its upper edge, with discontinuous dark brown line above yellowish white line extending to end of fold; apex with a small dark brown speckle; termen dark brown; cilia concolorous with wing except grayish white at apex. Hindwing and cilia grayish brown. Fore- and midlegs grayish brown; hindleg silvery gray.

Male genitalia ( Fig. 122 View FIGURES 117 – 122 ): Uncus degenerate. Socius broadened and incurved from base to 5/6, distal 1/6 narrowed sharply to a thorn. Ventral plate of gnathos almost rounded. Valva nearly semicircular. Saccus shorter than socius, parallel-sided to rounded apex. Anellus a quarter length of phallus, densely spinous on distal half. Phallus stout, curved slightly at middle, about 1.5 times length of valva; coecum 1/5 length of phallus; cornuti about 1/2 length of phallus, composed of two broad rows of microspines, each row with several large spines at end.

Female genitalia ( Fig. 169 View FIGURES 164 – 169 ): Intersegmental membrane between papilla analis and 8th abdominal segment 1/2 length of abdomen. Apophyses posteriores about 1.6 times length of apophyses anteriores. Lamella postvaginalis V-shaped. Antrum slender, cup-shaped. Ductus bursae longer than corpus bursae, broadened gradually from inception of ductus seminalis to corpus bursae. Corpus bursae sacklike; signum about 3/5 length of corpus bursae, ridged at anterior 1/4 and posterior 1/6 respectively.

Distribution. China (Xinjiang).

Etymology. The specific epithet is derived from the Latin mucronulatus, meaning with sharp end, referring to the male socius with distal 1/6 narrowed sharply to a thorn.
