Comments |
This taxon was originally described as Emys depressa by Spix (1824:5), but that name had already been used by Merrem (1820:22) to describe material now referable to Phrynops geoffroanus. Duméril and Bibron (1835:409) provided the first unique name for this taxon (Platemys Spixii) based on MNHN 8751. However, because the latter is only a replacement name for Emys depressa Spix, the type material of the latter become the types of Platemys Spixii (e.g., see Rhodin, da Rocha e Silva, and Mittermeier, 1984). Hoogmoed and Gruber (1983:345) examined the only remaining syntype of E. depressa Spix (ZSM 3003/0) and designated it as the lectotype of that taxon, and by convention, of P. spixii as well. Reviewed by Groombridge (1982; as Platemys spixii), Ernst (1983b; as Platemys spixii; although his distribution map is in error), Rhodin, Mittermeier, and McMorris (1984; as Platemys spixii), Rhodin, da Rocha e Silva, and Mittermeier (1984; as Platemys spixii), Waller (1988), and Buskirk (1991). |
