Upperside dark purple-brown. Male: forewing with a golden yellow oblique discal sinuous band followed by small costal spots before the apex; base of the costa and cell, and two spots at its end also of the same colour; hindwing with a medial discal sinuous golden-yellow band, the hairy scales extending to the base also yellow. Cilia golden yellow. Underside with less distinct markings as above: costa and apex of forewing and the hindwing suffused with yellow. Body and legs golden-yellow; palpi and front of thorax beneath saffron-yellow. Female: differs only in the discal band being narrow; and not having the yellow costal streak.Edward Yerbury Watson ^[4]

"Nearest allied species is Oriens gola . Differs from it on both sides in the narrower discal band of the forewing, the band being also disconnected from the costal spots; the band of the hindwing is also narrower." (Frederic Moore)

The larvae are known to feed on Axonopus compressus and Oplismenus compositus . ^[5]
