is a small-size ornamental freshwater species. In the present study, the complete mitochondrial genome of was first determined using the next-generation sequencing technology. The result showed that the circular mitogenome was 16,675 bp in length, contained 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and two non-coding regions: origin of light-strand replication (OL) and displacement loop locus (D-loop). In addition to ND6 and eight tRNA genes, most mitochondrial genes were encoded on the heavy strand. Furthermore, the overall base composition was 29.97% A, 26.12% T, 26.86% C, 17.04% G, respectively, and showed AT-rich feature (56.09%). Moreover, phylogenetic analysis based on the tandem 13 PCGs nucleotide sequences indicated that had a close relationship with and . The complete mitogenome sequence of would contribute to the better understanding of molecular systematics, selection, conservation, species identification and evolution of this species.
是一种小型观赏淡水物种。在本研究中，首次使用下一代测序技术确定了其完整的线粒体基因组。结果表明，环状线粒体基因组长度为16,675 bp，包含13个蛋白质编码基因（PCGs）、两个核糖体RNA（rRNA）基因、22个转移RNA（tRNA）基因以及两个非编码区：轻链复制起点（OL）和位移环位点（D-loop）。除了ND6和8个tRNA基因外，大多数线粒体基因在重链上编码。此外，总体碱基组成为A占29.97%、T占26.12%、C占26.86%、G占17.04%，呈现出富含AT的特征（56.09%）。而且，基于串联的13个PCGs核苷酸序列的系统发育分析表明，与和具有密切关系。该物种完整的线粒体基因组序列将有助于更好地理解该物种的分子系统学、选择、保护、物种鉴定和进化。
