Ypsolopha fascimaculata sp. nov.

( Figs 17 , 68, 117, 165)

Type material. Holotype: ♂, China, Ningshan County (33°19′ N, 108°20′ E), Shaanxi Province, 2300 m, 7.viii.1987, coll. Houhun Li. Paratypes: 3 ♂♂, same data as for holotype except dated 8.viii.1987; 1 ♀, Jiuzhaigou (33°17′ N, 103°54′ E), Sichuan Province, 2700 m, 13.viii.2002, coll. Shulian Hao.

Diagnosis. This species is characterized by the forewing having about 50 dark brown dots ( Fig. 17 ). It is similar to Y. albula sp. nov. in the male genitalia, but can be distinguished by the valva roundly protruding dorsally beyond middle ( Fig. 117 ), which is slightly arched distally in the latter species ( Fig. 115 ).

Description. Adult ( Fig. 17 ): Wing expanse 20.0 mm. Head yellowish white, grayish brown around eyes. Antenna white, flagellum ringed with brown on distal half. Labial palpus white, mottled yellowish, pale yellowish brown on basal segment and on outer surface of second segment; tuft of second segment triangular, much shorter than labial palpus; third segment conspicuously longer than second. Thorax yellowish white, with a longitudinal median ocherous brown streak, reaching near posterior margin. Tegula ocherous brown. Forewing with R4 and R5 short stalked or connate (Figs 68a-b); ocherous brown, weakened to pale yellow toward apex; longitudinal pale brown to ocherous brown median streak extending from base to apex; 50 dark brown dots arranged as follows: five to six from above base of Sc to 1/4 of costa, ten along R1, about ten along R2, five between R2 and streak near costa, ten on distal 4/5 of cell on median streak, about six along distal 2/3 of fold, about five near termen and on tornus; dorsum slightly pale yellow, with black patch above base; cilia pale yellow. Hindwing gray, cilia whitish gray. Fore- and midlegs grayish brown; hindleg grayish white, pale yellowish white on inner side, grayish brown on tarsus. Abdomen with dorsal surface gray, ventral surface light yellowish brown.

Male genitalia ( Fig. 117 ): Uncus degenerate. Socius slender, with pointed tip. Ventral plate of gnathos semicircular. Valva narrowed at base, roundly protruding beyond middle along dorsal margin. Vinculum developed, with small process on both sides. Saccus only 1/3 length of socius, dilated apically. Anellus about 2/5 length of phallus, densely spinous on distal half. Phallus nearly as long as valva, curved strongly at middle; coecum dilated, about 1/5 length of phallus; cornuti about 2/5 length of phallus, composed of two rows of microspines.

Female genitalia ( Fig. 165 ): Intersegmental membrane between papilla analis and 8th abdominal segment about half length of abdomen. Apophyses posteriores about 1.5 times length of apophyses anteriores. Lamella postvaginalis V-shaped. Antrum cup-shaped. Ductus bursae slender, about 1.5 times length of corpus bursae, expanded gradually from inception of ductus seminalis to corpus bursae, granulous on posterior 1/3. Corpus bursae rounded; signum about a quarter length of corpus bursae, surrounded by granules, ridged at anterior 1/4 and posterior 1/4 respectively.

Distribution. China (Shaanxi, Sichuan).

Etymology. The specific epithet is derived from the Latin prefix fusc -, meaning brown, and the Latin maculatus , meaning maculate, refers to the brown dots on the forewing.
