We reported the complete mitochondrial genome yielded using next-generation sequencing of in this study. The total length of the mitochondrial genome is 16,562 bp, with the base composition of 32.6% A, 25.9% T, 26.8% C, and 14.7% G, in several. It contains two rRNA genes, 22 tRNA genes, 13 protein-coding genes, and a 945 bp non-coding control region (D-loop region). The sequence of these genes is consistent with that found in the Siluriformes. The complete mitogenomes of and other 17 species of fish were constructed by phylogenetic analysis using Neighbour-Joining method. The topological structure indicated that species participating in the analysis belong to three groups (Siluridae, Loricariidae, and Callichthyidae) of nine genera, and the i was clustered with other species from genus . The external morphological characteristics of are consistent with the results of molecular classification, so the mitogenome can be used to identify species in the future.
在本研究中，我们报告了通过下一代测序获得的完整线粒体基因组。线粒体基因组的总长度为16,562 bp，在几个方面的碱基组成为32.6%的A、25.9%的T、26.8%的C和14.7%的G。它包含两个rRNA基因、22个tRNA基因、13个蛋白质编码基因和一个945 bp的非编码控制区（D环区域）。这些基因的序列与鲇形目鱼类中发现的序列一致。通过邻接法进行系统发育分析，构建了该物种以及其他17种鱼类的完整线粒体基因组。拓扑结构表明，参与分析的物种属于九个属的三个类群（鲇科、甲鲇科和丽鲇科），并且该物种与来自该属的其他物种聚类在一起。该物种的外部形态特征与分子分类结果一致，因此线粒体基因组未来可用于鉴定该物种。
