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.
