( Figs 52 View FIGURES 48 – 54 , 101 View FIGURES 98 – 104 , 152 View FIGURES 147 – 152 , 196 View FIGURES 194 – 197 )

Type material. Holotype: ♂, China, Mt. Xinglong, Yuzhong County (35°53′ N, 104°06′ E), Gansu Province, 2178 m, 21.vii.2007, coll. Feng Yang & Hanguang Gao, genitalia slide No. JQ07304. Paratypes: 1 ♂, 1 ♀, same data as for holotype except dated 19−21.vii.2007; 1 ♀, Mt. Li, Jincheng (35°30′ N, 112°51′ E), Shanxi Province, 1520 m, 19.viii.2006, coll. Xu Zhang & Haiyan Bai.

Diagnosis. The new species is similar to Y. blandella (Christoph) in appearance and in the male genitalia, but can be distinguished by the white band between the fold and the dorsum on the forewing having a black dot at basal 1/5 and at middle ( Fig. 52 View FIGURES 48 – 54 ), the relatively long saccus that is as long as the socius and the extremely slender phallus in the male genitalia ( Fig. 152 View FIGURES 147 – 152 ); in Y. blandella (Christoph) , there are no such dots on the forewing as above, the saccus is shorter than the socius and the phallus is stout in the male genitalia ( Fig. 149 View FIGURES 147 – 152 ). Ypsolopha bisticta sp. nov. is close to Y. aurea sp. nov. in the female genitalia, but differs in the relatively long intersegmental membrane between the papilla analis and the 8th abdominal segment that is 3/5 length of the abdomen, and the long apophysis posterioris that is about 2.5 times length of the apophysis anterioris ( Fig. 196 View FIGURES 194 – 197 ); in Y. aurea sp. nov., the intersegmental membrane between the papilla analis and the 8th abdominal segment is 1/2 length of the abdomen, and the apophysis posterioris is about twice length of the apophysis anterioris ( Fig. 192 View FIGURES 188 – 193 ).

Description. Adult ( Fig. 52 View FIGURES 48 – 54 ): Wing expanse 25.0 mm. Vertex rough, yellowish white; face white, pale brown around eyes. Antenna yellowish white, scape white ventrally, flagellomere ringed with pale yellowish brown. Labial palpus yellowish white, brown on outer surface of second segment; tuft of second segment slender, slightly shorter than labial palpus; third segment extremely short, concealed in tuft of second segment. Thorax white. Tegula pale brown. Forewing with CuA1 and CuA2 connate ( Fig. 101 View FIGURES 98 – 104 ); yellowish brown, with scattered dark brown scales near dorsum and at tornus, with white to yellowish white streak along veins; cell with black dot at 3/5 on upper margin and at end near lower angle respectively, with longitudinal narrow white median streak from near base to end of cell; fold dark brown on basal 2/3; yellowish white band between fold and dorsum, with black dot at its basal 1/5 and middle respectively; cilia yellowish brown. Hindwing and cilia yellowish white. Foreleg brown, grayish white on femur; mid- and hindlegs grayish white, mid tibia, tarsus, and hind tarsus grayish brown.

Male genitalia ( Fig. 152 View FIGURES 147 – 152 ): Uncus being a small semicircular projection. Socius slender, ending in point. Ventral plate of gnathos ovate, densely spinous. Valva ovate, concave near base on ventral margin. Saccus as long as socius, parallel-sided. Anellus 1/5 length of phallus. Phallus 1.2 times length of valva, dilated at inception of ductus ejacuiatorius, slightly curved at middle; coecum a quarter length of phallus; cornuti 3/10 length of phallus, composed of two slender spines.

Female genitalia ( Fig. 196 View FIGURES 194 – 197 ): Intersegmental membrane between papilla analis and 8th abdominal segment 3/5 length of abdomen. Apophyses posteriores about 2.5 times length of apophyses anteriores. Lamella postvaginalis V-shaped. Antrum slender, parallel-sided. Ductus bursae slightly longer than corpus bursae, smooth, thickened and curved before corpus bursae. Corpus bursae nearly elongate ovate; signum a quarter length of corpus bursae, ridged at anterior 1/4, narrowed posteriorly.

Distribution. China (Gansu, Shanxi).

Etymology. The specific epithet is derived from the Latin prefix bi -, meaning two, and the Latin stictus, meaning dot, referring to the two black dots at basal 1/5 and at middle of the white strip between the fold and the dorsum of the forewing.
