Medicinal leeches in the genus have been utilized for therapeutic procedures for thousands of years. To date, six known species of are widely distributed in different regions of the Eurasian continent. In this study, a new medicinal leech species Liu, is described based upon specimens collected from Tianjin City, China. The new species can be distinguished from its congeners by a combination of characters: blackish green dorsum with five continuous yellow longitudinal stripes; six sensillae on dorsal annulus a2 of segments VIII-XXV; greyish green ventrum with irregular bilateral dark brown spots; dorsum and abdomen separated by a pair of pale yellow stripes; front half atrium wrapped by white prostate; apparent albumen gland; epididymis massive in relation to ejaculatory bulb. The phylogenetic tree based upon COI implies a sister relationship to Whitman, 1886. A key to the known species is provided.
蛭属的药用蛭已被用于治疗程序数千年。迄今为止，已知的六种蛭广泛分布于欧亚大陆的不同地区。在本研究中，基于从中国天津市采集的标本描述了一种新的药用蛭物种——刘氏蛭。该新物种可通过以下特征组合与同属其他物种区分开来：背呈黑绿色，有五条连续的黄色纵向条纹；第八至二十五节背环a2上有六个感觉器；腹呈灰绿色，有不规则的双侧深褐色斑点；背腹由一对浅黄色条纹隔开；前半段心房被白色前列腺包裹；有明显的蛋白腺；附睾相对于射精球较大。基于细胞色素氧化酶亚基I（COI）构建的系统发育树表明它与1886年的惠特曼蛭是姐妹关系。还提供了已知物种的检索表。
