Description

FIGURE 2. Estimated mtDNA ND4 phylogeny for the Iguana iguana species complex. Numbers above branches are the estimated nucleotide substitutions (converted from ML substitutions per site) and bootstrap support for nodes is indicated below, when> 0.70. The four color-coded clades are those previously identified within the I. iguana species complex (Stephen et al. 2013). Taxonomy for the I. iguana species complex follows ITWG (2016, 2022). Bold and underlined locality codes indicate samples assigned to I. melanoderma by Breuil et al. (2020); A and B indicate: Subclade A, the smallest subclade including all haplotypes previously referred to the proposed I. melanoderma and Subclade B, the largest subclade including those haplotypes and excluding all haplotypes previously referred to species other than the proposed I. melanoderma. Locality codes marked with asterisks indicate sequences generated in the current study.
