Hindwing wing base more reddish brown and black brown; postmedial line indistinct, composed of dots on veins; a small reddish brown oval patch present between CuA 1 and CuA 2 outside postmedial line; discal spot black, long bar-like. Terminal line black, broken on veins, broader on hindwing. Fringe white alternated with grey-brown, more grey-brown upper half. Venter wing base greyish yellow, outside wing base to discal spot greyish black, spreading to lower margin of cell; forewing with broad black terminal band, tapering and broken posteriorly, almost absent between M 3 and CuA 1; discal spot black, oblong; hindwing with terminal band discontinuous, patchy medially; discal spot black, long narrow, bar-like. Abdomen: Dull white mixed with grey-black scales, dorsal crests developed, grey reddish brown (dull whitish in female). Male genitalia ( Figs 23 , 30 ) with socii fused basally, converging, tapering apically. Gnathos with median process pointed, spinulose. Valva well divided into costal lobe and sacculus. Costal lobe with apical and ventral side irregularly dentate; with medial, ventral ridge, but not forming distinct extending process. Sacculus relatively broad, apex slightly narrower, ventral margin wrinkled medially, posterior and apical margins irregularly serrate. Transtilla a pair of expanded processes, slightly sclerotized. Coremata well developed. Semicircular saccus distinctly protruding. Aedeagus short and broad, narrower and strongly sclerotized posteriorly, with large number of spinules; vesica without cornuti.
