|Taxonomic Notes:||The previous Red List assessments for Galapagos tortoises treated the various allopatric island populations as subspecies of Chelonoidis nigra, as did several authors (Pritchard 1996; Caccone et al. 1999; Beheregaray et al. 2003; Fritz and Havas 2007; TTWG 2007, Rhodin et al. 2008). However, other authors have considered them as full species based on morphology (Bour 1980; Fritts 1983; Ernst and Barbour 1989) and more recently several researchers (Cacconeet al. 2002; Russello et al. 2005, 2007; Poulakakis et al. 2008, 2012, 2015; Chiari et al. 2009) have treated most of them as full species based on congruent patterns of mitochondrial and nuclear variation. This elevated species-level taxonomy has been largely accepted by TTWG (2009, 2014) and TEWG (2015) for most, but not all, phylogenetic lineages of Galapagos tortoises. This Red List assessment therefore now treats C. hoodensis as a full species, rather than retaining its previous subspecies ranking from earlier Red List assessments.
This is an amended assessment to accommodate the change in taxonomy as described above. The amended assessment includes all the references cited above even though most of them post-date the actual date of assessment.
