CommentNomenclature: Vogt et al. (2013) proposed in ICZN Case 3587 to conserve the name Podocnemis unifilis TROSCHEL 1848. Mittermeier and Wilson (1974) and Wermuth and Mertens (1977:121) believed that Emys cayennensis Schweigger 1812 may be an older name applicable to this species. Acting on Fretey's (1977) information about the type specimens of Emys dumeriliana and E. cayennensis, Hoogmoed and Gruber (1983:346) concluded that dumeriliana was an older available name for unifilis, and that cayennensis was a junior synonym of P. expansa. Pritchard and Trebbau's (1984) review showed the holotype of E. cayennensis, MHNH 8359, is a P. unifilis and that action by the Intl. Comm. Zool. Nomencl. may be necessary to suppress the variously applied cayennensis in favor of the more stable unifilis (after KING & BURKE 1989).
