The complete mitochondrial genome of the fish leech from China has been determined for the first time in this study. It was 16,161 bp in length and consisted of 22 tRNA genes, two rRNA genes, 13 protein-coding genes (PCGs), and one control region. The nucleotide base content of mitogenome was 35.5% A, 10.4% C, 10.4% G, and 43.7% T. Start codon ATG was used in PCGs, while most of the termination codons are incomplete T or TA. The tRNA genes were ranged from 59 bp (tRNA-Arg and tRNA-Glu) to 69 bp (tRNA-Gln and tRNA-Cys) in length. The phylogenetic tree was constructed and suggested that has closer relationship to the , , , , , , , and , and that they constitute a sister group.
本研究首次测定了来自中国的鱼蛭的完整线粒体基因组。其长度为16161 bp，由22个tRNA基因、2个rRNA基因、13个蛋白质编码基因（PCGs）和1个控制区组成。线粒体基因组的核苷酸碱基含量为A 35.5%、C 10.4%、G 10.4%、T 43.7%。PCGs中使用起始密码子ATG，而大多数终止密码子为不完整的T或TA。tRNA基因长度范围为59 bp（tRNA-Arg和tRNA-Glu）至69 bp（tRNA-Gln和tRNA-Cys）。构建的系统发育树表明，其与[具体物种1]、[具体物种2]、[具体物种3]、[具体物种4]、[具体物种5]、[具体物种6]、[具体物种7]和[具体物种8]关系更近，它们构成一个姐妹群。 （注：原文中“suggested that has closer relationship to the...”部分缺失具体物种信息）
