Abstract

Fourteen taxa are described from Hemingfordian (early Miocene) to Hemphillian (early Pliocene) deposits of western North America and Florida. New taxa include Edaphocyon lautus, new species; Arctonasua floridana, new genus and species; Arctonasua gracilis, new species; Arctonasua minima, new species; Arctonasua eurybates, new species; Arctonasua fricki, new species; Lichnocyon phoenicus, new genus and species; and Paranasua biradica, new genus and species. The earliest known occurrences (Hemphillian) of Nasua and Procyon are documented. Cladistic analysis demonstrates that Paranasua is the primitive sister taxon of Procyon and Nasua; that Arctonasua is probably most closely related to the late Tertiary Cyonasua group of South American procyonines; and that the primitive sister group of the Procyoninae discussed in this paper includes Bassariscus and the European Agenian and Orleanian (early Miocene) genus Broiliana.
