Redescription. Head: Antenna bipectinate in male, the longest pectination about five times diameter of antennal shaft, simple filiform in female. Frons greyish brown, smooth-scaled. Labial palpus blackish brown, short and stout, extending slightly beyond frons. Vertex greyish brown.
Thorax: Dorsal side greyish brown. Hind tibia in male without hair-pencil; with two pairs of spurs in both sexes. Forewing length: male 18–20 mm, female 19–21 mm. Wings pale grey. Forewing with outer margin weakly protruded; costa diffused with dull short longitudinal greyish brown flecks; antemedial line black, slightly protruded inwards below cell; medial line black, distinct; postmedial line black, slightly protruded outwards between M1 and M2, protruded inwards below M2, then paralleling to medial line; a yellowish brown patch outside postmedial line, the dull brown shadow in the middle of the patch indistinct; discal spot black, distinct. Hindwing with basal area greyish brown; medial line black, distinct, equal to postmedial line in width; postmedial line black, slightly protruded outwards between M1 and M3, then slightly protruded inwards below M3. Underside dull grey, postmedial line weak and indistinct, brown, forming black patch on costa of forewing.
Venation: Forewing: R1 and R2 separate and almost parallel in male, anastomosing in female; R3–5 diverging from before anterior angle of cell; M1 diverging from anterior angle of cell.
Abdomen: First abdominal segment with pale grey band dorsally, remaining segments greyish brown.
Male genitalia: Uncus triangular, length equal to basal width. Tegumen posterior processes absent. Gnathos with median process about one-third length of basal width. Valva terminally blunt and slightly slender, bearing a large area of long setae; one cluster of long setae near center, extending dorsally; ventral margin of valva not protruded outwards at middle. Saccus small, round. Juxta asymmetrical, left sclerotized process stick-like, same length as juxta. Spines bundle of cornuti strong, about two-fifths length of aedeagus.
Female genitalia: Sterigma with central part round, lateral sclerotized lobes short. Ductus bursae about two-fifths length of corpus bursae, strongly sclerotized. Corpus bursae oval, signum irregularly shaped, with six big teeth and some small protrusions around margin.
Diagnosis. This subspecies is similiar to the nominate subspecies, but the dull brown shadow is less distinct in the middle of the yellowish brown patch outside the postmedial line on both wings, and the forewing postmedial line is less protruded outwards between M1 and M3.
