Diagnosis.

Antenna with black and white stripes, club thin and long. Male genitalia: tegumen not extend distally; uncus narrow; phallus with lateral process almost equal to subzonal sheath and not enlarged, distal half serrated.

Redescription.

Forewing length 15 ± 0.5 mm in males and 15.5 mm in females (Fig. 3E-G ). Antenna longer than half length of forewing. Labial palpi: second segment porrect and covered with long brown hairs, third segment short.

Male (Fig. 3E, F ). Forewing upper side: ground color brown with orange spots. Spots in spaces R1-R5 long radial and connected to discocellular vein; spots in space M1 to CuA2 form a broad brand, of which spot in space M1 very small; cell orange; stigma black-grey, thin and short. Hindwing upper side: ground color same as forewing, central part including cell and spaces Rs-CuA2 orange. Wing under side: ground color orange-yellow, with spots orange, and blurred.

Female (Fig. 3G ). Different from male in reduced spots in spaces R1, 2; only a couple of cell spots present on forewing; cell spot and spots in spaces Rs-CuA2 short and small on hindwing.

Male genitalia (n = 3) (Fig. 4E, F ). Tegumen not extend distally and shorter than uncus; uncus narrow and bifurcated at distal tip, with closely aligned arms; gnathos well-developed and bifid; valva long and narrow, dorsodistal process narrow and long, ventrodistal process widened and angled at the tip; phallus with lateral process almost equal to subzonal sheath, distal half not enlarged and serrated reaching the tip of phallus; juxta horseshoe shaped.

Female genitalia (Fig. 5C ). Papilla analis irregularly triangular in dorsal view; lamella antevaginalis trilobed shaped, lamella postvaginalis U-shaped, with upper margin straight and densely covered with fine hairs and spines; ductus bursae thick and short; bursa copulatrix oblong and membranous.
