Hindwing and fringe pale yellowish brown. Legs pale yellow; foreleg with tibia and tarsus dark yellowish brown on outer surface; midleg with tibia brown dorsally, with yellowish white bristles at middle and apex; hindleg with tarsus with yellowish white bristles at apices of basal two tarsomeres. Abdomen grey.

Male genitalia ( Fig. 35 ). Uncus wide at base, gradually narrowed to middle, distal half narrow, beak-shaped in lateral view. Gnathos triangular, wide at base, narrowed to pointed apex. Tegumen with height 1.5 times length of uncus. Valva wide at base, narrowed to cucullus; cucullus sub-elliptical, slightly narrowed to rounded apex, straight on dorsal margin, obtuse on ventral margin; costa sub-quadrate; sacculus narrowly banded, 3/5 length of valva, concave at middle on ventral margin, apex blunt, free from cucullus. Vinculum narrowly banded; saccus V-shaped, approximately 1/6 length of uncus. Juxta sub-rounded; anellar lobes elliptical, about same length as juxta, with short setae. Aedeagus same length as valva, basal 2/3 uniform, distal 1/3 gradually narrowed; with a sclerotized plate near base, with numerous spicules between basal 1/6 and 2/3; distal process slenderly clubbed, rounded at apex, 1/3 length of aedeagus.
