Diagnosis.

This species is hard to distinguish by its external characters. It differs from other species by the sacculus with a single process in the middle, while the sacculus usually has two processes in other species. Furthermore, the sclerotized plate on the valva is twice or three times as broad as others.

Adults. Forewing length 11.0-12.5mm (n = 6). Head blackish-brown; labial palpus upturned, mixed with fuscous and black scales, stronger in male; maxillary palpus pale yellow; antenna brown, scape extension black, mixed with fuscous scales in male. Thorax mixed with brown and fuscous scales. Forewing covered with brown, black and pink scales; base mixed with yellow and black scales; costal margin yellow; postmedial fascia orange with brown edges, outer area covered with pink and fuscous scales; cilia grey. Hindwing with same pattern as forewing.

Male genitalia (Fig. 21). Uncus broad, suffused with dense setae. Gnathos broad, base extended to two strongly sclerotized spine-like processes laterally located, apex with three spines. Valva nearly the same width from base to apex; costa extruded the apex of valva; sacculus with a single spine-like process in middle; a well-developed sclerotized broad plate from sacculus to centre of valva. Juxta bifurcated with two pointed plates at apex. Phallus slender, slightly curved.

Female genitalia (Fig. 31). Ovipositor broad, densely suffused with setae. Apophysis anterioris longer than apophysis posterioris. Ductus bursae slender, membranous. Corpus bursae round, with two rounded signa, slightly sclerotized.
