We describe the complete mitochondrial genomes of the flapper skate (Parnell 1837) and the longnose skate (Linnaeus 1758), which have been obtained by Sanger sequencing. We report the length of the sequences to be 16,906 and 16,911 bp, respectively. The length and structure of gene regions, containing 13 protein-coding regions, 22 tRNA genes, two rRNA genes, and two non-coding areas, resemble those of related skate species. Despite being considered a cryptic species with , the full mitogenomes confirm that and are more genetically similar. In comparison to other species, is missing a whole codon in its cytochrome oxidase subunit 2 gene. These mitogenomes will be a useful resource furthering investigation of the population genetic differences and evolutionary history of skate species.
我们描述了通过桑格测序获得的鲼形鳐（1837年，帕内尔）和长鼻鳐（1758年，林奈）的完整线粒体基因组。我们报告这两个序列的长度分别为16,906和16,911碱基对。基因区域的长度和结构，包括13个蛋白质编码区、22个tRNA基因、两个rRNA基因和两个非编码区，与相关鳐类物种相似。尽管被认为是一个隐性物种，但完整的线粒体基因组证实它们在基因上更为相似。与其他鳐类物种相比，鲼形鳐的细胞色素氧化酶亚基2基因缺失了一整个密码子。这些线粒体基因组将成为进一步研究鳐类物种群体遗传差异和进化历史的有用资源。
