Redescription. Head: Antenna bipectinate in basal two-thirds in male, longest pectination about three times diameter of antennal shaft, dorsal rami a little longer than ventral rami; filiform at tip and in female. Frons with dorsal half white, ventral half grey-black, ventral margin yellow. Labial palpus yellow, dotted with darkbrown distally, extending beyond frons in both sexes. Vertex white. Thorax: Tegula white internally, dark-grey externally. Prothorax white. Dorsum white, suffused with brown, venter yellow. Hind tibia of male dilated, with hairpencil and terminal tuft. Forewing length 25–27 mm in ♂, 27–30 mm in ♀. Wings ivory-white, suffused with various dark grey blotches and yellow. Forewing with subbasal and antemedial lines dark, immerged in grey blotches; a large grey patch on discal spot; postmedial line composed of row of blotches, continuous or interrupted between M 3 -CuA 1; terminal area with broken grey blotches, suffused with yellow, which extends to anal angle; terminal line a row of black dots; fringe grey-white alternated with black-grey. Hindwing with discal spot small; blotches composed of postmedial line, larger near costa, interrupted between Rs and M 1, M 3 and CuA 2; yellow patches occupying almost entire anal angle. Venter white, base yellow; patches similar to that of dorsum, black-brown, extending slightly; terminal area not suffused with yellow. Abdomen: Dull yellow crests on dorsum of segments 3 and 4, edged with two blackish lines. Two additional blackish lines present laterally and dorsally. Sternite 3 of male abdomen with a pair of setal patches. Male genitalia ( Figs. 18 , 25 ) with socii fused in basal two-thirds. Gnathos with median process pointed, spinulose. Valva divided into strongly sclerotized costal lobe and sacculus. Costal lobe irregularly wrinkled, with a median spinose ridge, extending anteriorly, forming a blunt process. Sacculus broad, apex rounded, becoming narrower distally; ventral margin irregularly wrinkled near middle, posterior margin above with row of small spines. Transtilla with a pair of slightly sclerotized, large, expanded processes, not joined. Saccus slightly elongate, with rounded apex. Coremata present. Aedeagus short, broad posteriorly; more sclerotized posteriorly with large number of spinules; vesica without cornuti. Female genitalia ( Fig. 32 ) with apophyses anteriores extremely short, much shorter than apophyses posteriores. Ostium located between segment 7 and 8; surrounding region sclerotized, wrinkled, lamella postvaginalis rounded. Ductus bursae very short, slightly sclerotized, without distinct antrum. Corpus bursae very large, elongate, membranous; signum absent.
