利用形态学特征和线粒体细胞色素c氧化酶亚基I和烟酰胺腺嘌呤二核苷酸脱氢酶亚基1基因研究了舌蛭科（Rhynchobdellida）的系统发育关系。35个分类群代表10个目前公认的23个属的glossiphoniid采样，包括超过70%的已知北美物种，以及其他来自欧洲，南美，非洲，和贝加尔湖特有的物种。外群类群包括鱼鳃科和Ozobranchidae的物种。支序分析得到1个最简约的树。亚科的区别，即，Haementeriinae，Theromyzinae和Glossiphoniinae，已经基于眼睛形态学和生殖生物学没有得到证实。结果还提供了几个有问题的属级分类的见解。例如，阐明了Placobdella和Haementeria的关系，并可能需要消除Desserobdella。脊椎动物的吸血被认为是一种原始的特征，在进化枝中已经丢失了两次。的biannulate水蛭，Oligobdella biannulata，代表一个重要的过渡形式的假设是重新评估的系统发育背景下。
The phylogenetic relationships of the Glossiphoniidae (Rhynchobdellida) were investigated using morphological characters and the mitochondrial genes cytochrome c oxidase subunit I and nicotinamide adenine dinucleotide dehydrogenase subunit 1. Thirty-five taxa representing 10 of the 23 currently recognized glossiphoniid genera were sampled, including more than 70% of known North American species, as well as others from Europe, South America, Africa, and a species endemic to Lake Baikal. Outgroup taxa included species from the Piscicolidae and Ozobranchidae. Cladistic analysis resulted in 1 most-parsimonious tree. Subfamily distinctions, i.e., Haementeriinae, Theromyzinae, and Glossiphoniinae, that have been based on eye morphology and reproductive biology are not corroborated. Results also provide insights into several problematic genus-level classifications. For example, relationships of Placobdella and Haementeria are clarified and elimination of Desserobdella may be necessary. Bloodfeeding from vertebrates is seen to be a primitive characteristic that has been lost twice within the clade. The hypothesis that the biannulate leech, Oligobdella biannulata, represents an important transitional form is re-evaluated in a phylogenetic context.
