Regan 1906 is a member of the family Nemacheilidae, Cypriniformes, and native loach in Yunnan. In this study, the complete mitochondrial genome (mitogenome) of Regan 1906 was firstly reported and analyzed. The mitogenome of Regan 1906 is 16,566 bp in length, including 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs), and one control region (D-loop). The arrangement and orientation of protein coding genes and RNAs in Regan 1906 are identical to other species of Nemacheilidae. The base composition of Regan 1906 mitogenome was 29.25% A, 28.55% T, 25.03% C, and 17.17% G. The phylogenetic analysis based on the mitogenome showed that Regan 1906 belongs to the clade of genus and the monophyly of is identified. This study contributed valuable genetic data for Regan 1906 and explored the phylogenetic relationships in Nemacheilidae.
雷氏南鳅1906是鲤形目条鳅科的一员，是云南的本土鳅类。在本研究中，首次报道并分析了雷氏南鳅1906的完整线粒体基因组（线粒体基因组）。雷氏南鳅1906的线粒体基因组长度为16,566 bp，包括13个蛋白质编码基因（PCGs）、22个转运RNA（tRNAs）、两个核糖体RNA（rRNAs）和一个控制区（D-loop）。雷氏南鳅1906中蛋白质编码基因和RNA的排列及方向与条鳅科的其他物种相同。雷氏南鳅1906线粒体基因组的碱基组成为：A占29.25%、T占28.55%、C占25.03%、G占17.17%。基于线粒体基因组的系统发育分析表明，雷氏南鳅1906属于某属的分支，且该属的单系性得到确认。本研究为雷氏南鳅1906提供了有价值的遗传数据，并探讨了条鳅科的系统发育关系。
