Torodora ventrimaculata Yu et Wang , sp. nov.

( Figs 16 , 34 )

Type material. CHINA, Hainan: Holotype ♂, Tianchi (18°26′N, 108°31′E), Jianfengling, 787 m, 6.III.2016, leg. QY Wang, SR Li & SN Zhao, slide No. YS 20350.

Diagnosis. This new species is similar to T. roesleri Gozmány, 1978 superficially by the forewing with a darkcolored discocellular stigma, the termen with several dark-colored dashes, and the dorsum with a dark-colored spot. It can be distinguished in the male genitalia by the uncus widened from middle to before triangular apex, and the parallel-sided valva; in T. roesleri , the uncus is narrowed from base to apex, and the valva is broad basally and narrowed distally ( Gozmány 1978: Pl. 47, fig. 125).

Description. Adult ( Fig. 16 ). Wingspan 17.0 mm.

Head yellowish brown. Antenna pale yellow. Labial palpus brown except orange white apically on second palpomere and dorsobasally on third palpomere, third palpomere as long as second palpomere.

Thorax and tegula yellowish brown. Forewing with costal margin slightly arched, apex roundly produced, termen shallowly concave; ground color yellowish brown, mixed with sparse dark brown scales; discal and plical stigmata small, dark brown; discocellular stigma elliptical, dark brown; dorsum with a larger dark brown spot at distal 1/3; with eight dark brown spots spaced along distal 1/6 of costal margin and termen; fringe pale orange. Hindwing and fringe greyish brown; fringe with an orange white basal line. Legs pale yellow on dorsal surface, on ventral surface dark brown except pale yellow at base and at apex of first tarsomere and on entire second tarsomere.

Male genitalia ( Fig. 34 ). Uncus wide at base, narrowed to middle, thereafter widened to before triangular apex. Gnathos with mesial process elongate, wide at base, narrowed to pointed apex, curved ventrad slightly before apex. Valva almost parallel-sided, apex obtuse; costa shallowly concave; ventral margin obtusely arched distally; sacculus wide at base, narrowed to basal 2/5 of ventral margin of valva, gently arched inward ventrally. Vinculum narrow, rounded on anterior margin. Juxta subrectangular, wider than long, shallowly concave on posterior margin, subtriangularly produced at middle on anterior margin; posterolateral lobe horn-shaped, as long as juxta, setose distally. Aedeagus as long as valva, straight, tubular in basal 2/3, narrowed from distal 1/3 to obtuse apex; cornuti consisting of a cluster of spines ventrally at distal 1/3 and a cluster of strong granules dorsally before apex.

Female unknown.

Distribution. China (Hainan).

Etymology. The specific epithet is derived from the Latin ventr- and maculatus, referring to the forewing with a spot on the dorsum.
