The complete mitochondrial genome of <i>Mesogobio lachneri</i> (Cypriniformes: Gobionidae) from Northeast Asia

Although <i>Mesogobio lachneri</i> is the type species of the genus <i>Mesogobio</i>, its systematic position and status have remained unresolved to date. In this study, for the first time, we report the complete mitochondrial genome of <i>M. lachneri</i> using Sanger sequencing. It is a circular genome with a length of 16,602 bp, comprising 22 tRNAs, 13 protein-coding genes (PCGs), two rRNAs, and one non-coding control region. Our phylogenetic analysis reveals that <i>M. lachneri</i> is the close relative of the genus <i>Gobio</i>, indicating that <i>Mesogobio</i> may be a valid genus.
