"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.^[2]
