Redescription. Head: Antenna bipectinate basally, ciliate at tip in male, the longest pectination about 1.5 times diameter of antennal shaft; filiform in female. Frons with dorsal margin white, ventral margin reddish brown, middle black. Labial palpus reddish brown, extending beyond frons; segments 2 and 3 rough-scaled. Vertex yellowish white. Thorax: Yellowish white dorsally, with reddish brown scales medially, pale yellow ventrally. Hind tibia with two pairs of spurs. Forewing length 26–28 mm in ♂, 33 mm in ♀. Wings dull white, suffused with grey-green, reddish brown, and black scales. Forewing with subbasal line grey-green, broader on costa, dark-brown mixed with reddish brown, indistinct posteriorly; antemedial line black, nearly straight; area between subbasal and antemedial lines white mixed with grey-green; reddish brown from antemedial line to discal spot extending to costa, mixed with some grey-green; apex with a large blotch, reddish brown mixed with dark-brown and grey-green, weak serrate submarginal line visible inside blotch; postmedial line serrate, indistinct, with small black dots on veins, distally more whitish; terminal line black mixed with reddish brown, interrupted on veins; discal spot black, elongate, bordered with reddish brown; fringe white between veins, reddish brown, mixed with grey-green at termination of veins, more reddish brown and dark brown between M veins. Hindwing concolorous with other parts of wing, base not suffused with reddish brown scales; postmedial line same as that of forewing, forming small patch on inner margin, black-brown mixed with little reddish brown; narrow ovoid patch between CuA 1 and CuA 2, a second grey green patch at anal angle; terminal line broader than that of forewing; fringe same as that of forewing. Venter white suffused with black patches, wing base yellow; forewing with discal spot oblong, black-brown, cell area pale grey-brown, with grey-brown patch basally below cell; postmedial line bandlike, discontinuous, broader above M 3; terminal band broader anteriorly, narrower posteriorly, paler at apex, posterior half with several long narrow black barlike patches. Hindwing with discal spot large, black, spreading in cell; postmedial line bandlike, discontinuous, forming a larger black patch on costa; terminal line composed of three large black separate patches on costa, between M veins, between CuA 1 and inner margin; terminal line black, broad. Abdomen: Pale reddish brown dorsal crests on segments 1 to 4, those on 2 and 3 more developed, black on two sides of crests. Sternite 3 of male abdomen with a pair of setal patches. Male genitalia ( Figs. 21 , 28 ) with socii fused in slightly greater than basal one-half, tapering distally, with a tiny acute point apically. Gnathos with median process pointed, spinulose. Costal lobe well sclerotized, apex expanded, rounded, with irregular spines on apical and anterior margin, with an irregularly serrate ridge medially, ventrally, extending proximally anteriorly, forming a process. Sacculus with narrow rounded apex, ventral margin straight with a small depression medially, distal margin with tiny spines. Coremata well developed. Transtilla with pair of weakly sclerotized, expanded processes. Saccus elongate, rounded. Aedeagus short, broad posteriorly; more sclerotized posteriorly, with large number of spinules; vesica without cornuti. Female genitalia ( Fig. 35 ) with apophyses anteriores much shorter than apophyses posteriores. Region around ostium transversely wrinkled and sclerotized, lamella postvaginalis rounded. Ductus bursae very narrow, short (relatively long for genus), less than one-fourth length of corpus bursae, slightly sclerotized, wrinkled, without antrum. Corpus bursae large, broad, membranous, with a lateral expanded membranous process; signum absent.
