Redescription. Head: Antenna bipectinate in basal two-thirds, filiform in terminal one-third in male, longest pectination about two times diameter of antennal shaft; filiform in female. Frons with dorsal half and ventral margin white, black medially. Labial palpus dark brown mixed reddish brown, yellowish brown ventrally, not extending beyond frons. Vertex white. Thorax: Dorsum grey-white to yellowish brown, mixed with black scales. Hind tibia with two pairs of spurs. Forewing length 24 mm in ♂, 29–34 mm in ♀. Wings whitish, wing base, costal area and apex on forewing suffused with dense purplish red striations, extending to inner margin between antemedial line to discal spot, tapering posteriorly; terminal area grey-green. Forewing with subbasal, antemedial line straight, oblique, black; area between these two lines pale grey-green; postmedial line black accompanying white, incomplete, indistinct, only small black dots on veins, sometimes distinct above M 3; submarginal line white, serrate, sometimes not very distinct. Hindwing postmedial line more distinct than that of forewing, broad, very dark near inner margin; outside postmedial line with long patch between CuA 1 and CuA 2, black intermixed with red scales; postmedial line, patch, outer margin, and inner margin almost forming closed area, more grey-green inside; submarginal line whitish, dentate or wavy, terminating at patch between CuA 1 and CuA 2. Terminal line black, interrupted, comparatively broader on hindwing; fringe greywhite, barlike. Venter mostly white, yellow basally; grey-black from outside yellow base to discal spot, not restricted to cell, extending nearly to inner margin. Postmedial line with only few irregular black patches, on hindwing with three patches, most posterior patch almost connected to patch on anal angle; forewing with greyish black patch on apex, sometimes extending posteriorly to anal angle, tapering gradually; hindwing with terminal line broad, narrow bandlike. Occasionally, almost no streaks on dorsum except nearly closed patch on anal angle of hindwing. Abdomen: Dorsum grey-white to yellowish brown, mixed with black; with greyish red dorsal crests; two black lines accompanying dorsal crests laterally. Male genitalia ( Figs. 19 , 26 ) with socii fused basally, tapering. Gnathos with median process pointed, spinulose. Valva divided into two strongly sclerotized lobes. Costal lobe with smooth dorsal margin, apical margin wrinkled, crenulated; irregularly wrinkled ventrally, and with a sclerotized blunt process transversing anterior half, posterior margin of which also wrinkled irregularly or spinose. Sacculus with apex slightly narrower, ventral margin with depression at middle, irregularly wrinkled, posterior margin with row of small spines. Transtilla a pair of large expanded processes, slightly sclerotized. Saccus protruding, with rounded apex. Coremata present. Aedeagus short and posteriorly broad; with large number of spinules; cornuti absent. Female genitalia ( Fig. 33 ) very similar to those of amplificata in shape and structures, but lamella postvaginalis less defined.
