Base de Datos de las Especies de Galápagos

Categoría de taxón: Aceptado

Syn.: Chelonoidis nigrita (Duméril & Bibron, 1835), Geochelone nigrita (Duméril & Bibron, 1835), Testudo porteri Rothschild, 1903, Chelonoidis nigra porteri Rothschild, 1903, Geochelone porteri Fritts, 1983. Le et al. (2006) demonstrate that the genus Geochelone is polyphyletic and that the Galapagos Giant Tortoises are better treated as the monophyletic genus Chelonoidis. According to Márquez et al. (2004) and Poulakakis et al. (2008) the Geochelone taxa (= Chelonoidis) from Galapagos are genetically distinct and therefore treated as species and not as subspecies of Geochelone (= Chelonoidis) nigra.
