Diagnosis
This species is distinguishable from congeneric species by having the relatively broad white bands on the forewing. The male genitalia are also differentiated from others by having a pair of large and heavily sclerotized hook-shaped lobes on the juxta, the valva bearing only one cucullus and the phallus with a lateral and apical projections.
Description
Adult ( Figure 1 View Figure 1 (e), 1(f)). Head: Frons white, vertex white basally, tinged with dark brown, occiput pale yellowish dark brown. Antenna: Scape white entirely, 2/3 length of diameter of eye; fragellum white near base, white and dark brown alternately dorsally. Labial palpus: 2nd palpomere yellowish dark brown, except white near apex; 3rd palpomere white, except dark brown near apex, slightly shorter than 2nd palpomere. Thorax: Thorax and tegula blackish dark brown. Wing expanse 7.0–8.0 mm. Forewing ground colour dark brown, tinged with blackish dark brown near wing base; four bands white slightly tinged with pale yellow, relatively broad, connected altogether, scattered by fuscous scales near tornus: antemedial band oblique toward wing base, transverse from 1/3 of costal margin reaching to greyish fuscous medial suffusion on posterior margin; medial band connected to antemedial and postmedial bands, relatively wider in width; postmedial band oblique toward apex, reaching 3/4 of costal margin; subapical band connected to former, traversed from 3/4 of costal margin to beyond tornus; fringes greyish dark brown tinged with pale whitish yellow near apex. Hind wing sub-lanceolate; ground colour pale greyish brown; fringes greyish brown.
Male genitalia ( Figure 2 View Figure 2 (g–i)). Uncus hook-shaped, concave laterally near base, setose laterally, slightly bent sub-apically. Gnathos membranous, small tongue-shaped, 1/2 length of uncus. Valva asymmetrical, bearing truncated, setose apex: cucullus on right valva heavily developed, sclerotized, large spine-shaped, thicker than process of sacculus; dense tuft apically on left valva; juxta extended, bearing a pair of lobes: both asymmetrical, heavily sclerotized, large hook-shaped, with 2–3 spines on left lobe, as long as cucullus; vinculum large. Saccus large triangular, longer than uncus. Phallus narrowed at base, gradually wider to 8/9, straight to 2/3, slightly bent, sclerotized luniform projection on lateral margin of subapex, sclerotized apex thumb-shaped, as long as valva plus saccus. Cornutus absent.
Female unknown.
