The freshwater leech Helobdella europaea Kutschera 1987 was discovered twenty years ago in Germany and described as a new species. Here, we show that this leech is genetically identical with the Australian species Helobdella papillornata (CO-I-mt-DNA sequence identity of alignment positions: 98%). We conclude that H. europaea (syn. H. papillornata) represents an introduced annelid that occupies the same ecological niche as the common European leech H. stagnalis L.
淡水水蛭欧洲扁蛭（Helobdella europaea Kutschera，1987年）于二十年前在德国被发现，并被描述为一个新物种。在此，我们表明这种水蛭在基因上与澳大利亚物种乳头扁蛭（Helobdella papillornata）相同（比对位置的细胞色素氧化酶亚基I线粒体DNA序列同一性：98%）。我们得出结论，欧洲扁蛭（同物异名：乳头扁蛭）是一种外来引入的环节动物，它与常见的欧洲水蛭欧洲医蛭（Hirudo medicinalis）占据相同的生态位。
