Antenna brownish yellow, with pale brown ring dorsally; length of ventral cilia c. one quarter of the flagellomere diameter of male. Labial palpus with basal two thirds white, black-brown distally. Maxillary palpus black-brown, pale brown at base. Patagium and tegula brown. Thorax pale brown distally, white ventrally. Wings dark brown, stigmata and lines black-brown. Forewing black-brown along basal costa; orbicular stigma very small; discoidal stigma crescent; postmedial line at c. three quarters of wing, nearly parallel to terminal margin, slightly excurved near costa. Hindwing with postmedial line slightly beyond basal half of wing, only middle part obvious. Cilia pale brown on forewing, yellowish white on hindwing; a brown line at base. Legs pale yellow. Front and middle tibiae yellowish brown; hind tibia with outer middle spurs c. half-length of inner spurs. Abdomen pale yellowish brown dorsally, each segment pale terminally.

Valva nearly rectangular, broad distally; costa sharply arched near base and accompanied by a cluster of long curved setae, then slightly concave towards apex; sacculus gradually narrowed distally, without long setal cluster. Phallus narrow medially, significantly inflated anteriorly and posteriorly, posterior half sclerotized; cornutus absent.
