Phiala abyssinica is a moth in the Eupterotidae family. It was described by Aurivillius in 1904. It is found in Ethiopia. The wingspan is 48 mm. The wings are greyish-white, densely irrorated with large black scales, except at costa of the forewings and at the base of the hindwings. The veins are also nearly destitute of black scales and the black scales on the forewings condensed to a broad curved stripe from near the apex to the middle of the hindmargin. The black spots on the veins of the hindwings are more or less indicated.
