revealed that the complete length of its mitochondrial genome was 16,568 bp, composed of A (31.7%), T (27.1%), G (15.9%), C (25.4%), and A + T (58.8%). Its genetic constitution and arrangement were consistent with other , including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control area (D-loop). All genes were encoded by the H-strand, except for one protein-coding gene (ND6) and eight tRNA genes (tRNA, tRNA, tRNA, tRNA, tRNA, tRNA, tRNA, tRNA) are encoded by the L chain, and the remaining genes are encoded by the H chain. The phylogenetic tree was divided into two main clades: one just including and the other including , , , , is distributed in Southwest Guizhou Province attached to Yunnan-Guizhou Plateau, is distributed in Hunan Province, they are near relatives, but their kinship with Triplophysa distributed in Tibetan Plateau is farther.
结果表明，其线粒体基因组全长16568bp，由A（31.7%）、T（27.1%）、G（15.9%）、C（25.4%）组成，A+T含量为58.8%。其基因组成和排列与其他物种一致，包括13个蛋白质编码基因、22个tRNA基因、2个rRNA基因和1个控制区（D-loop）。所有基因均由重链编码，除一个蛋白质编码基因（ND6）和八个tRNA基因（tRNA、tRNA、tRNA、tRNA、tRNA、tRNA、tRNA、tRNA）由轻链编码外，其余基因均由重链编码。系统发育树分为两个主要分支：一个仅包含[物种名称1]，另一个包含[物种名称2]、[物种名称3]、[物种名称4]、[物种名称5]，[物种名称1]分布于云贵高原附属的贵州西南部，[物种名称2]分布于湖南省，它们是近亲，但与分布于青藏高原的高原鳅属亲缘关系较远。
