A recent Internet search revealed the homonymy of the generic name Paulacoutoia, which was proposed by Cifelli (1983)for a South American didolodontid ?condylarth? of the Itaboraian South American Land Mammal Age (latePaleocene?early Eocene), whose type species P. protocenica was previously assigned by Paula Couto (1952) to Ernestokokenia Ameghino, 1901. Notwithstanding, the name Paulacoutoia was erected previously by Purper (1979) for a Miocene ostracod (Crustacea) genus. Currently, Paulacoutoia is a junior objective synonym of the ostracod genus Cyprideis Jones, 1857. Because the generic name Paulacoutoia is preoccupied, according to Articles 52, 53, and 60 of thecurrent edition of the International Code of Zoological Nomenclature (1999), the name of the extinct didolodontid becomes a junior homonym, and it must be rejected and replaced. We propose the name Depaulacoutoia, gen. nov., to replacePaulacoutoia Cifelli, 1983. This name is proposed to reflect the tribute made by Cifelli (1983) to the contributions of Carlos de Paula Couto (1910?1982) to knowledge of Brazilian fossil mammals. The name of the species of the monotypic genus Depaulacoutoia therefore becomes Depaulacoutoia protocenica (Paula Couto, 1952), comb. nov.
