已知的Praobdellid水蛭物种寄生于脊椎动物的粘膜;其中一些被认为是无脊椎动物的吸血者。Praobdellid个体被发现以日本淡水蟹Geothelphusa dehaani为食，在Mt。日本茨木县筑波市。水蛭把头伸进了螃蟹甲壳和腿之间的节间膜。我们的研究结果代表了第一个无脊椎动物的主机记录praobdellid水蛭。此外，基于核18 S和28 S rRNA，线粒体cytochromecoxidase亚基I和12 S rRNA序列以及水蛭形态特征的分子系统发育树显示，本水蛭可能属于一个未识别的praobdelid谱系：日本praobdelid物种的分类修订是必要的。
Praobdellid leech species have been known to infest vertebrate mucous-membrane; some of them have been assumed to be invertebrate bloodsuckers. Praobdellid individuals were found feeding on the Japanese freshwater crab,Geothelphusa dehaani, at Mt. Tsukuba, Ibaraki Prefecture, Japan. The leech had inserted its head into the intersegmental membrane between the crab's carapace and legs. Our findings represent a first invertebrate host record for praobdellid leeches. Additionally, molecular phylogenetic trees based on nuclear 18S and 28S rRNA, mitochondrial cytochromecoxidase subunit I, and 12S rRNA sequences as well as the leech morphological characteristics showed that the present leech might belong to an unrecognized praobdellid lineage: a taxonomic revision of the Japanese praobdellid species is needed.
