The complete mitochondrial genome sequence of has a circular genome of 14,149 bp, comprised of 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and a control region. The nucleotide composition is 35.82% of T, 35.13% of A, 17.19% of G, and 9.16% of C. Most genes are encoded on the heavy strand except seven tRNA genes (, , , , , , ), four protein-coding genes (, , , ), and 16S-rRNA on the light strand. Most protein-coding genes start with TTG, ATT or ATA initiation codon except cox1, cox1's start codon cannot be determined, and three types of inferred termination codons are TAA, TAG, and an incomplete stop codon. There are four intergenic spacers and 25 gene overlaps. The phylogenetic analysis shows that has closer genetic relationship with (von Wirth, 1991) and (Raven & Schwendinger, 1898) with high bootstrap support.
的完整线粒体基因组序列具有一个14,149 bp的环状基因组，由13个蛋白质编码基因、两个rRNA基因、22个tRNA基因和一个控制区组成。核苷酸组成是T占35.82%，A占35.13%，G占17.19%，C占9.16%。除了七个tRNA基因（，，，，，，）、四个蛋白质编码基因（，，，）和轻链上的16S - rRNA外，大多数基因在重链上编码。除cox1外，大多数蛋白质编码基因以TTG、ATT或ATA起始密码子开始，cox1的起始密码子无法确定，推断的终止密码子有三种类型，即TAA、TAG和不完全终止密码子。有四个基因间隔区和25个基因重叠。系统发育分析表明，与（冯·维尔特，1991年）和（雷文与施温丁格，1898年）具有更密切的遗传关系，自展支持率高。
