本文报道了采自白纹螺（Gyraulus albus（Müller））和扁螺（Planorbis planorbis（L.）收集于德国和捷克共和国的囊蚴和棘腹鱼的囊蚴。（Gasterosteiformes：Gasterosteidae）收集在加拿大的特点是形态和分子。本文详细描述了寄生虫、尾蚴和囊蚴，并与已有的关于Petasiger属幼虫期的资料进行了比较。利用28S rDNA和nad1线粒体序列的比较分子分析支持的不同地位的四种Petasiger。分子和形态学的证据，它们的区别和更新的检索表已知的大尾尾蚴Petasiger从古北。
Large-tailed echinostomatid cercariae of the genus Petasiger Dietz, 1909 (Digenea: Echinostomatidae) from the planorbid snails Gyraulus albus (Müller) and Planorbis planorbis (L.) collected in Germany and the Czech Republic and metacercariae from Gasterosteus aculeatus L. (Gasterosteiformes: Gasterosteidae) collected in Canada are characterised morphologically and molecularly. The rediae, cercariae and metacercariae are described in detail and compared with the existing data on the larval stages of Petasiger spp. Comparative molecular analyses using 28S rDNA and nad1 mitochondrial sequences supported the distinct status of four species of Petasiger. Molecular and morphological evidence for their distinction and an updated key to the known large-tailed cercariae of Petasiger from the Palaearctic are provided.
