Type material. Holotype ♂, CHINA, Hainan Province, Wuzhishan City, Shuiman Town (18.88°N, 109.67°E), 766 m, 7.vii.2015, leg. Qingyun Wang, Suran Li and Mengting Chen, genitalia slide no. LGE19013.

Diagnosis. Superficially, this species is distinguished by the narrow forewing with a distinct black spot on the termen. The male genitalia are characterized by the medially convex costa of the valva and the straight distal part of the aedeagus.

Description. Adult ( Fig. 61 ). Head: Silvery white. Labial palpus silvery white except palpomere III dark fuscous. Antenna with scape silvery white; flagellum dark fuscous except basal 1/3 of dorsal surface mixed with silvery white, male cilia slightly longer than diameter.

Thorax: Dorsum and tegula silvery white. Wingspan 5.5 mm; forewing ground color light grey, base with glossy creamy white scales, gradually darkening toward apex, anterior edge of costa black in basal half; an elliptical orange patch in distal 1/3 of wing between costa and posterior 1/4, its outer margin almost reaching apical spot; between the patch and apical spot a narrow white line extended to tornus; apical spot large, below this a smaller black spot on termen, tinged with orange between two spots; dorsum suffused with fuscous, orange after fold; fringe scales grey, mixed with cream along distal part of dorsum. Hindwing grey except apex black; fringe scales grey and cream mixed, apical fringe with a black terminal band. Legs silvery white, hind tibia suffused with fuscous in distal half, mid- and hind tarsi strongly mixed with fuscous.

Abdomen ( Fig. 24 ): Male coremata as long as sternum VIII; sternum VIII sub-pentagonal, rounded laterally. Male genitalia ( Fig. 80 ) with uncus small, pentagonal, with a medial ridge. Gnathos hook short, thickened after base, gradually narrowed to acute apex. Tegumen approximately 6 times as long as uncus; a set of papilliform tubercles at middle, each bearing a long hair ( Fig. 41 ). Valva slender, slightly curved inward, widest at middle, costa broadly convex at middle, rounded apically. Anellus lobe oval, approximately 1/5 length of valva; apical bristle longer than anellus lobe, strongly incurved. Juxta with inner margin broadly convex, a very short projection at distal 1/3. Vinculum broad and simple. Saccus knobbed. Aedeagus with basal 1/3 dilated, distal 2/3 slender and straight, acute apically.

Female unknown.

Distribution. China (Hainan).

Etymology. The species name is derived from the Latin magnus (large) and guttatus (spotted), referring to the large black spot on the termen of the forewing.
