ADULT (Figs 1B, 2B). Wingspan 10.0‒ 11.5 mm. Head and antenna orange white. Second palpomere of labial palpus orange white mixed with dark brown on inner surface, dark brown on outer surface, roughly scaled ventrally; third palpomere orange white. Thorax orange white; tegula dark brown. Forewing with costal margin slightly arched, apex roundly produced, termen shallowly concave; ground colour dark brown, mixed with orange-white scales, orange white mixed with brown ventrobasally, blackish brown from base to antemedian fascia along costal margin; antemedian fascia orange white, curved in S shape from beyond basal 2/5 of costal margin to basal 2/5 of dorsum, edged with black scales on inner margin; discocellular stigma elliptical, black, encircled by orange white; costal spot small, orange white, at distal ¼; dorsal spot smaller, orange white, at distal ¼; subterminal line orange white, running from below costal spot sinuate to dorsal spot, discontinuous; fringe greyish black, basal line orange white; M 1 stalked with R 3+4+5, M 2+3 and CuA 1+2 short-stalked, CuA 1 and CuA 2 coincident. Hindwing brown; fringe greyish brown, with an orange-white basal and median lines. Legs orange white mixed with dark-brown scales except foreleg dark brown ventrally.
MALE GENITALIA (Fig. 3B). Uncus wide at base, narrowed to apex, sparsely setose distally.Gnathos with basal plate roundly produced posteriorly; median process wide at base, narrowed to distal 1/5, distal 1/5 slender, hooked, pointed at apex. Valva wide at base, narrowed to distal ⅓, distal ⅓ clavate, strongly upturned, apex rounded, slightly widened; costa deeply concave distally; sacculus broad basally, slightly narrowed distally, straight ventrally, about 3/5 length of ventral margin of valva. Juxta widened lateromedially, triangular on anterior margin; posterior margin with a large clavate process at middle, as long as uncus, with tooth at apex; posterolateral lobe thumbed; lateral lobe digitate, longer than posterolateral lobe, setose distally. Vinculum widened anteriorly forming subquadrate saccus. Aedeagus shorter than valva, straight, broad at base, narrowed to obtuse apex, with dense granules in vesica; cornutus situated distally, narrowly banded, slightly shorter than ⅓ length of aedeagus, with several teeth of variable size.
FEMALE GENITALIA (Fig. 4B). Eighth abdominal sternite concave at middle on posterior margin. Apophyses posteriores about 1.5 times as long as apophyses anteriores. Lamella antevaginalis broadly banded, spiculose. Antrum weakly sclerotized. Ductus bursae about 2.5 times as long as corpus bursae, twisted twice, with sparse spines running from below ductus seminalis to posterior ¼; ductus seminalis narrowed basally, helical, arising from below antrum. Corpus bursae small, ovoid; signum situated at middle, elliptical, serrate along margins, with narrow, horizontal central groove.
