Taxon category: Accepted

Syn.: Geochelone nigra spp.. 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. According genetic and mophological study, the data confirm the new species on Santa Cruz Island (Poulakakis etal. 2015).

Status

IUCN Red List Category: Not evaluated

Distribution

Distribution: Restricted on Cerro El Fatal and Cerro Mesa, Santa Cruz Island.
