Ypsolopha longisaccata sp. nov.

( Figs 16 , 67, 116)

Type material. Holotype: ♂, China, Jiuzhaigou (33°17′ N, 103°54′ E), Sichuan Province, 2700 m, 13.viii.2002, coll. Shulian Hao, genitalia slide No. JQ07056. Paratypes: 2 ♂♂, same data as for holotype, one with abdomen missing; 1 ♂, Halawu (33°50′ N, 105°50′ E), Inner Mongolia Autonomous Region, 2200 m, 9.viii.2011, coll. Lixia Li & Yinghui Mu.

Diagnosis. This species is similar to Y. fascimaculata sp. nov. in appearance, but can be distinguished by the forewing having a white strip extending from end of cell to apex ( Fig. 16 ), which is absent in the latter species. The male genitalia are characterized by the long saccus about 1.5 times length of the socius ( Fig. 116 ).

Description. Adult ( Fig. 16 ): Wing expanse 23.0 mm. Head ocherous brown, with yellowish white median strip; face pale yellow, dark brown mixed with grayish white around eyes. Antenna white, ocherous brown on outer side of scape, ringed with brown on each flagellomere. Labial palpus brown except white on dorsal surface of basal and second segments; tuft of second segment triangular, less than half length of labial palpus, puffed; third segment slightly longer than second. Thorax grayish brown, with dark brown strip along both margins. Tegula yellowish brown. Forewing with R4 and R5 stalked (Fig. 67); pale ocherous brown, dark brown along basal 5/6 of fold; with about 35 dark brown dots arranged in three rows: one row with 12−15 dots extending from 1/5 of Sc to 2/3 of costa, another row with about 6 dots ranging from 2/5 to 4/5 of R1, a third row with about 15 dots extending along dorsum; dark brown streak from near base broadened to end of cell, then extending to apex in a narrow straight stripe, a straight white strip above it parallely extending from end of cell to apex; dorsum white at base; cilia pale ocherous yellow. Hindwing grayish brown; cilia gray, with a grayish white basal line. Fore- and midlegs grayish brown mixed with white; hindleg grayish white, mixed with grayish brown on outer side, grayish brown at base of femur, spurs black.

Male genitalia ( Fig. 116 ): Uncus a small arch. Socius slender, with pointed tip. Ventral plate of gnathos semicircular. Valva narrowed at base, widened gradually to apex. Saccus elongate, about 1.5 times length of socius, dilated before slightly pointed apex. Anellus about a quarter length of phallus, densely covered with short hairs on distal half. Phallus about twice length of valva, straight; coecum broader than and 1/6 length of phallus, inception of ductus ejacuiatorius near base of phallus; cornuti 3/5 length of phallus, composed of two rows of microspines, each row with one larger spine on end.

Female: Unknown.

Distribution. China (Inner Mongolia, Sichuan).

Etymology. The specific epithet is derived from the Latin prefix longi -, meaning long, and the Latin saccatus, meaning saccate, referring to the long saccus in the male genitalia.
