Type material. Holotype ♂, CHINA, Guangxi Zhuang Autonomous Region, Jinxiu, Dayaoshan Nature Reserves (24.15°N, 110.21°E), 1364 m, 21.vii.2015, leg. Mujie Qi and Shengnan Zhao, genitalia slide no. LGE16111 . Paratypes. Guangxi Zhuang Autonomous Region: 1 ♂, same data as holotype except 19.vii.2015, genitalia slide no. LGE16112 . Fujian Province: 1 ♂, Sangang (27.45°N, 117.41°E), 740 m, Mt. Wuyi, 19.v.2004, leg. Haili Yu, genitalia slide no. ZJL05256 .

Diagnosis. Tenupalpa latifasciata sp. nov. is most similar to T. nephodesma; the two share a broad fascia on the forewing and a short projection from the costa of valva. The new species can be distinguished from the latter by the shape of the costal projection, which is longer and slenderer than that of T. nephodesma . The curved, finger-shaped anellus lobes of the male genitalia are also diagnostic for T. latifasciata .

Description. Adult (Fig. 48). Head: Creamy white. Labial palpus creamy white; palpomere III strongly mixed with brownish grey, as long as II. Antenna with scape creamy white; flagellum dark fuscous, except basal 1/3 of dorsal surface creamy white, male cilia as long as flagellomere diameter.

Thorax: Creamy white. Tegula creamy white, except anterior margin slightly tinged with fuscous. Wingspan 7.0–8.0 mm; forewing basal 1/3 creamy white, anterior edge of costa black; a broad, fuscous transverse fascia between 1/3 and 2/3 of wing, its posterior margin creamy white; distal 1/3 creamy white to brownish grey, strongly mixed with fuscous at apex; fringe scales brownish grey. Hindwing grey; fringe scales brownish grey. Legs creamy white; mid-tibia sometimes with a black spot at distal 1/3; hind tibia broadly black between distal 1/2 and 1/4, black at apex; mid- and hind tarsi strongly mixed with brownish grey.

Abdomen: Male coremata nearly as long as sternum VIII; sternum VIII pentagonal, shortly concave distally (Fig. 16). Male genitalia (Fig. 67) with uncus small and triangular, protruded medially, distal 1/2 covered with minute protuberances. Gnathos hook short and thick, tapering from middle to apex, pointed apically. Tegumen with diaphragma spinous in posterior 1/2, anterior 2/5 bearing papilliform tubercles (Fig. 28). Valva slender, strongly curved inward after base, gradually broadening toward apex; costa with an elongate-triangular projection at middle. Anellus lobe digitate, 1/5 length of valva, strongly curved inward, bifid apically; subapical bristle as long as anellus lobe. Juxta with inner margin broadly convex, with sparse setae at middle. Vinculum broad, sub-trapezoidal. Saccus short and broad, sub-triangular. Aedeagus with basal half dilated and distal 1/2 slender, blunt at apex.

Female unknown.

Distribution. China (Fujian, Guangxi).

Etymology. The species name is derived from the Latin latus (broad) and fasciatus (fasciate), referring to the broad fascia of the forewing.
