Torodora atomata Yu et Wang , sp. nov.

( Figs 2 , 20 )

Type material. CHINA, Shaanxi: Holotype ♂, Hualongshan Town (32°18′N, 109°22′E), Ankang County, 800 m, 2.VII.2003, leg. HL Yu, slide No. ZYM06217 . Paratype: 1♂, Jiangxing Village , Ankang County, 800 m, 5.VII.2003, leg. HL Yu, slide No. ZYM06231 .

Diagnosis. This new species is similar to T. zhejiangensis sp. nov. in both appearance and male genitalia. It can be distinguished by the ventral process of the cucullus curved outward at middle, the anterior pair of the lateral lobes narrowed distally and lacking spines; in T. zhejiangensis sp. nov., the ventral process of the cucullus is straight, and the anterior pair of the lateral lobes is widened distally and has spines.

Description. Adult ( Fig. 2 ). Wingspan 25.0‒25.5 mm.

Head brown. Antenna with scape brown; flagellum pale yellow, shortly ciliate ventrally in male. Labial palpus with second palpomere pale yellow on inner surface, brown on outer surface, orange white at apex; third palpomere pale yellow dorsally, brown ventrally, as long as second palpomere.

Thorax and tegula brown. Forewing with costal margin slightly arched, apex obtuse, termen oblique; ground color brown; costal spot pale orange, small, wedge-shaped, before distal 1/3; discocellular stigma dark brown, subrounded; subterminal line pale yellow, obscure, from costal spot oblique outward to M 1, then oblique inward to distal 1/5 of dorsum; fringe brown, tipped with pale yellow. Hindwing and fringe brown; fringe with an orange white basal line. Legs pale yellow except femora and tibiae of fore- and hindlegs brown ventrally, tarsi dark brown dorsally at middle of first tarsomere, and at base of remaining tarsomeres.

Male genitalia ( Fig. 20 ). Uncus broad basally, narrowed to narrowly rounded apex. Gnathos with basal plate quadrate, concave on posterior margin; mesial process large, falcate. Valva relatively narrow at base, widened to before middle, thereafter abruptly constricted to cucullus; cucullus bent obliquely ventrad, about 1/3 length of valva, widened medially, narrowed from middle to an acute apex, with a large horn-shaped ventral process longer than twice of basal width, gently curved outward at middle; costa slightly arched in basal half, shallowly concave at middle, strongly arched distally; sacculus narrowly banded in basal half, almost right-angled and bearing a cluster of piliform setae ventromedially, narrowed obliquely dorsad from middle to neck of cucullus. Vinculum narrow, obtuse on anterior margin. Juxta large, shallowly concave on posterior margin, produced at middle on anterior margin, with two pairs of lateral lobes: posterior pair large, horn-shaped, longer than maximum width of juxta, extending obliquely inward, fused at apex, forming an oval circle; anterior pair strong, arising from base of posterior lobe, slightly longer than half length of posterior pair, narrowed at base, widened subbasally, slightly narrowed distally, apex obliquely straight. Aedeagus shorter than valva, strongly arched in C shape, narrowed from base to obtuse apex, with granules in vesica; cornuti consisting of a small, weakly sclerotized plate before middle length, and numerous spines running from before middle to apex.

Female unknown.

Distribution. China (Shaanxi).

Etymology. The specific epithet is derived from the Latin atomatus, referring to the forewing with a small costal spot.
