is an endemic species found in Nujiang River and Lantsang. In this study, the complete mitochondrial genome of was determined. The circular mitochondrial genome was 16,576 bp long, containing 13 protein-coding genes, two ribosomal genes (rRNA), 22 transfer RNA () genes, an origin of light-strand replication (OL), and one displacement loop locus (D-loop). Most genes were encoded on the heavy strand except for ND6 and eight genes. There were 11 regions of gene overlaps totaling 29 bp and seven intergenic spacer regions totaling 37 bp. The phylogenetic analyses were performed on the concatenated dataset of 28 protein-coding genes (PCGs), and the fishes of genus may have a close relationship with Schizothoracins (Schizothoracinae) compared to other Cyprinidae fishes.
是一种分布于怒江和澜沧江的特有物种。在本研究中，测定了该物种的完整线粒体基因组。环状线粒体基因组长度为16,576 bp，包含13个蛋白质编码基因、两个核糖体RNA（rRNA）基因、22个转运RNA（tRNA）基因、一个轻链复制起点（OL）和一个位移环区域（D-loop）。除了ND6和8个tRNA基因外，大多数基因都在重链上编码。共有11个基因重叠区域，总长29 bp，7个基因间隔区域，总长37 bp。基于28个蛋白质编码基因（PCG）的串联数据集进行了系统发育分析，与其他鲤科鱼类相比，该属鱼类可能与裂腹鱼亚科（Schizothoracinae）关系密切。
