The complete mitochondrial genome and phylogenetic analysis of <i>Syncrossus berdmorei</i> (Blyth, 1860) (Cypriniformes: Botiidae)

The mitochondrial genome of <i>Syncrossus berdmorei</i> has yet to be characterized. In this study, we sequenced and analyzed its complete mitochondrial genome, which is 16,553 base pairs and comprises 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and two non-coding regions, showing a strong A + T bias. Phylogenetic analyses using maximum likelihood and Bayesian inference indicated a close evolutionary relationship between <i>S. berdmorei</i> and <i>S. beauforti</i>, suggesting that Leptobotia hengyangensis may warrant reclassification into the <i>Sinibotia</i> genus. This research provides a genetic resource for Syncrossus and enhances our understanding of the evolutionary history and taxonomic relationships within Botiidae.
