We reported the complete mitochondrial genome yielded by next-generation sequencing of in this study. The total length of the mitochondrial genome is 16,916 bp, with the base composition of 32.49% A, 25.47% T, 27.12% C, and 14.91% G. It contains 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and a major non-coding control region (D-loop region). The arrangement of these genes is the same as that found in the Corydoras. The complete mitochondrial genomes of and other 12 species from Siluriformes were used for phylogenetic analysis using neighbor-joining method. The topology demonstrated that all species belong to four genera and are divided into two groups (Siluridae and Callichthyidae), the was clustered with genus Corydoras. molecular classification is consistent with the external morphological feature results, so the information of the mitogenome could be used for future identification of .
我们在本研究中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16,916 bp，碱基组成为32.49%的A、25.47%的T、27.12%的C和14.91%的G。它包含2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（D环区）。这些基因的排列与在甲鲶属中发现的排列相同。使用邻接法对该物种和其他12种鲇形目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，所有物种属于四个属，分为两组（鲇科和美鲶科），该物种与甲鲶属聚集在一起。分子分类与外部形态特征结果一致，因此线粒体基因组信息可用于该物种未来的鉴定。
