The wingspan is about 21 mm. The forewings are pale yellow, the costa and veins tinged with fulvous. The antemedial line is fuscous and oblique and there is a fuscous discoidal bar. The postmedial line is fuscous, slightly bent outwards between veins 5 and 2, then retracted to the lower angle of the cell, and oblique to the inner margin near the antemedial line. There is a fuscous terminal line. The hindwings are pale yellow with a fuscous discoidal spot and a fuscous postmedial line, bent outwards between veins 5 and 2, then retracted to the lower angle of the cell and oblique to above the tornus. There is also a fuscous terminal line.
The larvae feed on Cola nitida and Theobroma cacao.
