A. cosmodora was described by Edward Meyrick in 1888 as Larentia cosmodora using material he collected at Gordon's Pyramid on Mount [Arthur (New Zealand)|Mount Arthur] in January. George Hudson also discussed this species under the name Xanthorhoe clarata in both 1898 and in 1928. In 1971 J. S. Dugdale confirmed the placement of this species in the genusAsaphodes.

The female holotype specimen is held at the Natural [History Museum, London].
