( Figs 50 View FIGURES 48 – 54 , 99 View FIGURES 98 – 104 , 150 View FIGURES 147 – 152 , 194 View FIGURES 194 – 197 )

Type material. Holotype: ♂, China, Xunhua County (35 ° 50 ′ N, 102 ° 28 ′ E), Qinghai Province, 2240 m, 15.vii. 1995, coll. Houhun Li & Shuxia Wang, genitalia slide No. JQ07053. Paratype: 1 ♀, Tianshui (34 ° 37 ′ N, 105 ° 42 ′ E), Gansu Province, 1331 m, 29.vii. 29, coll. Xinpu Wang & Xiangfeng Chi.

Diagnosis. The new species is characterized by having a pale green forewing ( Fig. 50 View FIGURES 48 – 54 ). It is similar to Y. blandella (Christoph)   and Y. bisticta   sp. nov. in the forewing having white strips along the veins, but differs in the forewing having a brown patch below middle of the fold, which is represented by a small dot in the latter two species. Ypsolopha chlorina   sp. nov. is similar to Y. umbrina   sp. nov. in the male genitalia, but differs in the relatively long saccus that is 3 / 4 length of the socius, and the narrow tongue-shaped ventral plate of the gnathos ( Fig. 150 View FIGURES 147 – 152 ); in Y. umbrina   sp. nov., the saccus is 3 / 5 length of the socius and the ventral plate of the gnathos is broadly tongue-shaped ( Fig. 140 View FIGURES 135 – 140 ). Ypsolopha chlorina   sp. nov. is also similar to Y. saitoi Moriuti   in the female genitalia, but can be separated by the corpus bursae irregularly elongate ovate and narrowed at middle ( Fig. 194 View FIGURES 194 – 197 ), while the corpus bursae is nearly rounded in the latter species.

Description. Adult ( Fig. 50 View FIGURES 48 – 54 ): Wing expanse 20.0 mm. Vertex rough, white, yellowish on both sides; face white, pale yellow around eyes. Antenna white, yellowish on dorsal side of scape, ringed with dark brown on each flagellomere. Labial palpus white, yellow on outer surface of second segment; tuft of second segment triangular, much longer than labial palpus; third segment less than half length of second. Thorax white. Tegula ocherous yellow. Forewing with CuA 1 and CuA 2 separated ( Fig. 99 View FIGURES 98 – 104 ); pale green, with metallic shine, with white strips along veins; costa with basal 1 / 2 white, distal 1 / 5 yellowish brown; fold brown on basal 2 / 3, with a black patch below middle; yellowish white mixed with brown between fold and dorsum; cilia brown. Hindwing pale grayish brown, darkened to brown toward apex; cilia yellowish white. Foreleg brown, scattered with white, white on ventral surface, ringed with white on each tarsomere; mid- and hindlegs white, mixed with brown on dorsal side, with white scales on dorsal side of tarsi.

Male genitalia ( Fig. 150 View FIGURES 147 – 152 ): Uncus small subulate. Socius slender, tapering. Ventral plate of gnathos narrowly tongue-shaped, densely spinous. Valva ovate, with distal third straight on dorsal margin. Saccus slender, 3 / 4 length of socius, truncate at apex. Anellus a quarter length of phallus. Phallus as long as valva, distally narrowed from inception of ductus ejacuiatorius, curved at middle; coecum 1 / 5 length of phallus; cornuti 3 / 10 length of phallus, composed of two rows of microspines.

Female genitalia ( Fig. 194 View FIGURES 194 – 197 ): Intersegmental membrane between papilla analis and 8 th abdominal segment 7 / 10 length of abdomen. Apophyses posteriores about twice length of apophyses anteriores. Lamella postvaginalis Vshaped. Antrum nearly cup-shaped. Ductus bursae 1.25 times length of corpus bursae, broadened slightly from inception of ductus seminalis to corpus bursae. Corpus bursae nearly rounded; signum about half length of corpus bursae, ridged at anterior 1 / 5.

Distribution. China (Gansu, Qinghai).

Etymology. The specific epithet is derived from the Latin chlorinus, meaning green, referring to the forewing colour.
