In this study, the complete mitochondrial genome of the was sequenced. The complete mitochondrial genome was circular and 15,288 bp in length, consisted of a typical set of 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and 1 non-coding control region. All these genes are in the heavy strand. The non-coding control region is 672 bp in length, and located between tRNA-Ser and tRNA-Leu. The overall nucleotides base composition of the heavy strand is 31.02% for A, 22.76% for C, 12.49% for G, and 33.73% for T, with a slight A + T-rich feature (64.75%). All of the PCGs begin with ATG as their start codon and the , and are terminated with TAA, , , , and are terminated with TAG, while others are terminated by incomplete codon T. Seen from the phylogenetic tree, has a more close relationship with than other species.
在本研究中，对该物种的完整线粒体基因组进行了测序。完整的线粒体基因组呈环状，长度为15288 bp，由一组典型的13个蛋白质编码基因（PCGs）、2个核糖体RNA（rRNA）基因、22个转运RNA（tRNA）基因和1个非编码控制区组成。所有这些基因都位于重链上。非编码控制区长度为672 bp，位于tRNA-Ser和tRNA-Leu之间。重链的总体核苷酸碱基组成为：A占31.02%，C占22.76%，G占12.49%，T占33.73%，具有轻微的A+T富集特征（64.75%）。所有的PCGs均以ATG作为起始密码子，其中， 、 和 以TAA作为终止密码子， 、 、 、 和 以TAG作为终止密码子，而其他的则以不完整密码子T作为终止密码子。从系统发育树来看，该物种与 相比，与其他物种的关系更为密切。
