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.
小安的列斯鬣蜥（Laurenti，1768年）是西印度群岛最濒危的脊椎动物类群之一。该物种面临着重大威胁，包括与引入的同属物种进行渐渗杂交。我们利用从Illumina读数获得的脱靶序列捕获和靶向桑格读数相结合的方法来组装[物种名称未给出]的线粒体基因组。该线粒体基因组长度为16,616 bp，由13个蛋白质编码基因、两个核糖体亚基（rRNA）、22个转运RNA和一个控制区组成。基因顺序与同属物种及其他密切相关类群相同，没有任何串联重复区域。我们通过最大似然分析展示了线粒体基因组的系统发育实用性，其产生的拓扑结构与之前对鬣蜥类群的研究一致。我们希望这一基因组资源将有助于为这种极度濒危物种的应用保护和管理提供更多信息。
