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.
