The Botia superciliaris is endemic to China and distributed mainly in the upper reaches of the Yangtze River. The complete mitochondrial genome was 16,597 bp in length, which contained 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 displacement loop (D-loop) locus. Except for the ND6 gene and eight tRNA genes, all other mitochondrial genes were encoded on the heavy strand. The overall nucleotide composition was 31.6% A, 25.5% T, 27.2% C and 15.7% G, with an AT content of 57.1%. The gene composition and the structural arrangement of the B. superciliaris complete mtDNA were identical to most of the other vertebrates. The molecular data here we presented could play a useful role to study the evolutionary relationships and population genetics of Cobitidae fish.
中华纹胸鮡是中国特有的物种，主要分布于长江上游。其线粒体基因组全长16,597 bp，包含13个蛋白质编码基因、22个tRNA基因、2个rRNA基因和1个位移环（D-loop）区域。除ND6基因和8个tRNA基因外，所有其他线粒体基因均由重链编码。总体核苷酸组成为31.6%A、25.5%T、27.2%C和15.7%G，AT含量为57.1%。中华纹胸鮡完整线粒体DNA的基因组成和结构排列与大多数其他脊椎动物相同。我们在此呈现的分子数据可能对研究鳅科鱼类的进化关系和群体遗传学发挥有益作用。
