The complete mitochondrial genome of the <i>Toxopneustes pileolus</i> Lamarck, 1816 (Echinoidea: Camarodonta: Toxopneustidae) and phylogenetic analysis

In this study, we report the complete mitochondrial genome sequence of <i>Toxopneustes pileolus</i> (Lamarck, 1816), which is the first complete mitochondrial genome of this genus <i>Toxopneustes</i>. The mitochondrial genome is 15,711 bp in length and includes 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and one non-coding control region (D-loop). Phylogenetic analysis based on mitochondrial genomes suggested a potential close relationship between the genus <i>Toxopneustes</i> and the genus <i>Lytechinus</i>. This study provided valuable genetic data for <i>T. pileolus</i> and contributed to the exploration of the phylogenetic relationships within the family Toxopneustidae.
