The complete mitochondrial genome of the critically endangered Lesser Antillean iguana (; Squamata: Iguanidae).

The Lesser Antillean iguana, Laurenti 1768, is one of the most endangered vertebrate taxa in the West Indies. This species faces significant threats, including introgressive hybridization with the introduced congener . We deploy a combination of off-target sequence capture obtained from Illumina reads and targeted Sanger reads to assemble the mitochondrial genome of . The mitogenome is 16,616 bp in length and is comprised of 13 protein-coding genes, two ribosomal subunits (rRNAs), 22 transfer RNAs, and a control region. Gene order is identical to that of congener and other closely related taxa, absent of any tandem repeat regions. We show the phylogenetic utility of the mitogenome with a maximum-likelihood analysis, which yields a topology concordant with previous studies of iguanine taxa. We are hopeful that this genomic resource will be useful in further informing applied conservation and management for this critically endangered species.
