The complete mitochondrial genome of Song 1977 from China has been determined and reported for the first time in this study. It was 14,625 bp in length and consisted of 22 tRNA genes, 2 rRNA genes, 13 protein-coding genes (PCGs), and 3 control regions. The nucleotide base content of the complete mitogenome for this species was 35.1% A, 10.5% C, 11.6% G, and 42.8% T. The tRNA genes were ranged from 57 bp (Ser) to 66 bp (Gln) in length. The phylogenetic analyses indicated that Hirudinea is a mono-phyletic clade. And it includes , , , , and . In Hirudiniformes, and three species of Haemopidae were obviously clustered into two independent branches. This result is consistent with a taxonomy that they all belong to the same suborder. This study adds to the genetic resources currently available for the species.
本研究首次测定并报道了来自中国的宋1977的完整线粒体基因组。其长度为14,625 bp，由22个tRNA基因、2个rRNA基因、13个蛋白质编码基因（PCGs）和3个控制区组成。该物种完整线粒体基因组的核苷酸碱基含量为A占35.1%、C占10.5%、G占11.6%、T占42.8%。tRNA基因长度范围为57 bp（Ser）至66 bp（Gln）。系统发育分析表明，蛭纲是一个单系类群。它包括 、 、 、 、 和 。在蛭形目中， 和血蛭科的三个物种明显聚为两个独立分支。这一结果与它们都属于同一亚目的分类法一致。本研究增加了该物种目前可用的遗传资源。
