A complete mitochondrial genome of the large scaled tongue sole ( <i>cynoglossus macrolepidotus</i> ) from the east China sea

The Large-scaled tongue sole (<i>Cynoglossus macrolepidotus</i>, Bleeker, 1851) is an economically important fish species in China. This study presents the first complete mitochondrial genome of the Large-scaled tongue sole, with a total length of 16,647 base pairs. The genome includes 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. Phylogenetic analysis reveals that <i>C. macrolepidotus</i> is genetically closer to <i>Cynoglossus joyneri</i> and <i>Cynoglossus puncticeps</i> than to other species within the <i>Cynoglossus</i> genus. This study provides valuable genetic data for future research on <i>C. macrolepidotus</i> and contributes to phylogenetic studies within the Cynoglossidae family.
