We present the complete mitochondrial genome of in this study. The results show that the mitochondrial genome is 16,640 bp in length, which is comprised of 13 protein-coding genes, two rRNA genes, and 21 tRNA genes. The nucleotide compositions of the light strand are 39.62% of A, 30.13% of T, 16.02% of C, and 14.24% of G. Except eight tRNA (Glu, Gly, Trp, Cys, Tyr, Met, Thr, Val) on the light strand, the rest are encoded on the heavy strand. All the protein-coding genes start with ATC initiation codon, and two types of inferred termination codons are TAA and TAG. There are 26 intergenic spacers and two gene overlaps. The phylogenetic analysis shows that clusters with and with high bootstrap support, which is consistent with the morphological and molecular evidence.
在本研究中，我们展示了[物种名称]的完整线粒体基因组。结果表明，线粒体基因组长度为16,640 bp，由13个蛋白质编码基因、两个rRNA基因和21个tRNA基因组成。轻链的核苷酸组成分别为：A占39.62%、T占30.13%、C占16.02%、G占14.24%。除轻链上的8个tRNA（Glu、Gly、Trp、Cys、Tyr、Met、Thr、Val）外，其余均由重链编码。所有蛋白质编码基因均以ATC起始密码子开始，推测的终止密码子有两种类型，即TAA和TAG。有26个基因间隔区和两个基因重叠区。系统发育分析表明，[物种名称]与[其他物种名称1]和[其他物种名称2]聚类，自展支持率高，这与形态学和分子证据一致。
