The wingspan is 15–16 mm. The forewings are rich saffron yellow, lightest at base, gradually deeper saffron toward the apex. At apical third is a hardly perceptible light ochreous costal streak, and similar light, inconspicuous dashes are found along the costal and dorsal edge on the apical third of the wing. Around the extreme apical edge is a prominent narrow black line before the cilia. The hindwings are dark fuscous.
