Two new species of Oppiidae are described, based on adults collected from Ethiopia. Arcoppia afroalpina Ermilov sp. nov. differs from its closely related species, A. arcualis arcualis by the morphology of the rostrum, the length and morphology of branches on the bothridial head, and the body size. Helioppia ethiopiaensis Ermilov sp. nov. differs from its closely related species, H. sol by the morphology of the rostrum, the morphology of the bothridial head, the development of the notogastral seta c, the location of the notogastral seta la, the presence of the costula, and longer notogastral setae. The generic diagnosis of Helioppia is presented.
