Taxonomy

This species was first described by Edward Meyrick in 1884 and originally named Xeroscopa octophora. He described this species more fully in 1885. He used species collected at various locations in the lower half of the South Island. George Hudson discussed and illustrated this species under the name Scoparia octophora, though his illustration was regarded by John S. Dugdale as dubious. In 1988 Dugdale placed this species in the genus Eudonia. The male lectotype specimen, collected at Castle Hill, Canterbury, is held at the Natural History Museum, London.
