Description D. ribbei Rob., from the Aru Islands, is a very rare species, of which sacha Gr.-Sm. is perhaps a local form. The white subapical spots on the underside of the forewing in ribbei are broader than in echo, the black submarginal band of the hindwing is narrowed, whilst the submarginal spots are strongly enlarged and assume a quadrate form.Hans Fruhstorfer in Seitz, A., 1912-1927.
