Type material. Holotype ♂, CHINA, Hainan Province, Jianfengling, Mingfenggu (18.74°N, 108.84°E), 954 m, 9.viii.2017, leg. Xia Bai, Ping Liu and Shuai Yu, genitalia slide no. LGE18036. Paratype. Hainan Province: 1 ♂, Tianchi (18.74°N, 108.84°E), 1050 m, Jianfengling , Ledong County, 29.iv.2013, leg. Yinghui Sun, Wei Guan and Tengteng Liu, genitalia slide no. LGE18010 .

Diagnosis. Superficially, this species is similar to several congeners; however, it may be distinguished by the short fuscous streak on the mid-tibia, which is usually absent in related species. The male genitalia are distinguished by the distally notched uncus, the flap-like extension of the basal half of valva, and the very small anellus lobe without bristles.

Description. Adult ( Fig. 62 ). Head: Silvery white. Labial palpus creamy white, palpomere III mixed with grey. Antenna with scape silvery white; flagellum dark fuscous except basal 1/3 of dorsal surface silvery white, male cilia as long as flagellomere diameter.

Thorax: Dorsum and tegula silvery white to grey. Wingspan 8.0 mm; forewing grey, lighter basally, anterior edge of costa black in basal 1/3; a fusiform orange patch in distal 1/2 to 1/3 of wing between costa and posterior 1/3, its inner margin sometimes narrowed toward base; apical spot large, dirty white between apical spot and former patch, extending downward toward tornus as a narrow line; a small, indistinct black spot near tornus below apical spot, tinged with orange between two spots; dorsum with an elongate, somewhat indistinct orange spot beyond fold; fringe scales grey, dark fuscous along termen. Hindwing grey except apex black and near apex cream; fringe scales grey, apical fringe with a black terminal band. Leg silvery white; mid-tibia with a short fuscous streak on outer surface before apex; hind tibia with distal half fuscous dorsally; mid- and hind tarsi strongly mixed with fuscous.

Abdomen ( Fig. 25 ): Male coremata slightly shorter than sternum VIII; sternum VIII sub-pentagonal, lateral margin rounded before middle, then gradually narrowing to posterior apex; posterior apex shortly emarginate. Male genitalia ( Fig. 81 ) with uncus cordate: base narrow, gradually broadening toward distal margin, middle of distal margin with a deep notch. Gnathos hook long and slender, curved at middle, acute apically. Tegumen approximately 3 times as long as uncus, a set of round tubercles at middle ( Fig. 42 ). Valva broad basally, gradually narrowing to about 1/3, then uniformly elongate to subapex, spatulate apically; basal half of costa with a flap-like extension with a crenate costa. Anellus lobe very small, rounded, without apical or subapical bristles. Juxta with base of inner margin slightly convex. Vinculum simple, posterior margin rounded. Saccus short, sub-triangular, not exceeding tegumen pedunculus. Aedeagus with basal 2/5 dilated, distal part slender and sinuous.

Female unknown.

Distribution. China (Hainan).

Etymology. The species name is derived from the Latin perparvus (very small) and lobus (lobe), referring to the very small anellus lobe.
