Recent studies have demonstrated the invalidity of the Pseudophyllidea, a long-term recognised order of tapeworms (Platyhelminthes: Cestoda), typical in possessing two dorsoventrally situated attachment organs called bothria. In fact, cestodes parasitic in tetrapods, especially mammals including man, form a relatively basal group called provisionally the "Diphyllobothriidea", whereas tapeworms occurring in freshwater and marine fish, with a few taxa known from amphibians (frogs and newts), belong to a more derived clade, for which the name "Bothriocephalidea" is tentatively proposed. Revision of the "Bothriocephalidea", based on literary data, study of type- and voucher specimens and extensive newly collected material made it possible to critically review the species composition of the group and to prepare a tentative list of its valid species. Out of 305 nominal taxa, only 125 species are considered to be valid. In addition, the spectrum of definitive hosts and geographical distribution of bothriocephalideans are briefly discussed.
最近的研究表明，假叶目（Pseudophyllidea）是无效的，它是绦虫（扁形动物门：绦虫纲）一个长期被认可的目，其典型特征是拥有两个位于背腹面的附着器官，称为吸槽。事实上，寄生于四足动物，尤其是包括人类在内的哺乳动物体内的绦虫，形成了一个相对基部的类群，暂称为“双叶槽绦虫目”（Diphyllobothriidea），而寄生于淡水和海洋鱼类中的绦虫，有少数类群见于两栖动物（青蛙和蝾螈），属于一个更为衍生的分支，暂为其命名“头槽绦虫目”（Bothriocephalidea）。基于文献资料、模式标本和凭证标本的研究以及大量新采集的材料，对头槽绦虫目进行修订，从而能够批判性地审视该类群的物种组成，并编制一份其有效物种的暂定清单。在305个命名分类单元中，只有125个物种被认为是有效的。此外，还对头槽绦虫类的终末宿主谱和地理分布进行了简要讨论。
