Type material. Holotype ♂, CHINA, Hainan Province, Ledong County, Jianfengling, Tianchi (18.74°N, 108.84°E), 1050 m, 30.iv.2013, leg. Yinghui Sun, Wei Guan and Tengteng Liu, genitalia slide no. LGE 19007 m.

Diagnosis. Tenupalpa dissimilis sp. nov. is similar to congeneric species, as described above, and it is difficult to separate based on the external features alone. However, the male genitalia are unique in the possession of asymmetrical anellus lobes which bear a robust, hook-shaped apical bristle.

Description. Adult (Fig. 65). Head: Denuded of scales. Labial palpus dirty white except palpomere III mixed with fuscous. Antenna with scape dirty white; flagellum dark fuscous except base of dorsal surface mixed with dirty white, male cilia slightly longer than diameter.

Thorax: Dorsum and tegula glossy grey. Wingspan 7.0 mm; forewing grey, anterior edge of costa black in basal half; an elliptical orange patch in distal 1/3 of wing, lying between costa and posterior 1/4, its outer margin almost reaching apical spot; a narrow dirty white line between former patch and apical spot, extending along termen; below apical spot a smaller, somewhat indistinct black spot on termen, between two spots slightly tinged with orange; dorsum suffused with orange beyond fold; fringe scales grey. Hindwing grey, except black at apex and dirty white near apex; fringe scales grey; apical fringe with a black terminal band. Legs silvery white; hind tibia dark grey dorsally; mid- and hind tarsi strongly mixed with dark grey.

Abdomen (Fig. 14): Male coremata nearly as long as sternum VIII; sternum VIII rounded. Male genitalia (Fig. 84) with uncus small, obcordate; distal margin deeply incised at middle, a sharp projection arising from the cleft. Gnathos hook moderately long, with basal 1/3 broadened, acute apically. Tegumen approximately 8 times as long as uncus; a set of papilliform tubercles at anterior 1/3, each tubercle bearing a long single hair (Fig. 45). Valva narrowed from base to middle, then broadening toward rounded apex. Anellus lobes different in size: left one much larger, rounded, approximately 1/2 length of valva, right one 1/3 length of valva; apical bristle robust, S-shaped, pointed apically. Juxta simple. Vinculum broad, simple. Saccus short, blunt. Aedeagus with basal 1/2 dilated, narrowed after middle, sinuous apically.

Female unknown.

Distribution. China (Hainan).

Etymology. The species name is derived from the Latin dissimilis (dissimilar), referring to the asymmetrical anellus lobes.
