In this study, the complete mitochondrial genome yielded by next-generation sequencing of was assembled and analyzed. The total length of the mitochondrial genome is 16,526 bp. It contains two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and a major non-coding control region . The arrangement of these genes is the same as that found in the Siluriformes. The complete mitogenomes of and other 17 species from nine genera were used for phylogenetic analysis by UPGMA method. The topology demonstrated that all species are divided into three groups , and the was clustered with and .
在本研究中，对通过下一代测序产生的完整线粒体基因组进行了组装和分析。线粒体基因组的总长度为16,526 bp。它包含两个核糖体RNA基因、13个蛋白质编码基因、22个转移RNA基因和一个主要的非编码控制区。这些基因的排列与鲇形目动物中发现的排列相同。使用UPGMA方法对该物种以及来自九个属的其他17个物种的完整线粒体基因组进行了系统发育分析。拓扑结构表明，所有物种分为三组，该物种与某物种和另一物种聚类在一起。
