Phylogenetic analyses based on partial 18S rDNA sequences of polyonchoinean monogeneans were conducted in order to investigate the relationships between selected families and subfamilies of the Dactylogyrinea, mainly within the Dactylogyridae. We tested the status of the Ancyrocephalidae sensu Bychowsky & Nagibina (1978) and the Ancyrocephalinae sensu Kritsky & Boeger (1989). Within the Dactylogyrinea, the Diplectanidae and Dactylogyridae are well supported by maximum likelihood and maximum parsimony analyses, but their phylogenetic relationship with the Pseudomurraytrematidae remains unresolved. Phylogenetic relationships between the Pseudodactylogyrinae, Ancyrocephalinae, Ancylodiscoidinae and Dactylogyrinae indicate paraphyly of the Ancyrocephalidae sensu Bychowsky & Nagibina (1978). The group of species recently considered as the Dactylogyridae sensu Kritsky & Boeger (1989) comprises two sister groups. The first group includes the freshwater Ancyrocephalinae and the Ancylodiscoidinae. The second group includes the Pseudodactylogyrinae, Dactylogyrinae and the Ancyrocephalinae from the fish species Siganus doliatus and Tetraodon fluviatilis. The non-monophyly of the Ancyrocephalinae (i.e. the non-monophyly of the group of species recently considered as members of Ancyrocephalinae), previously suggested by Kritsky & Boeger (1989) using the morphological characters, indicates that classification of the Dactylogyridae needs to be revised.
基于多钩亚纲单殖吸虫部分18S rDNA序列进行系统发育分析，以研究指环虫亚目选定科和亚科之间的关系，主要是指环虫科内部的关系。我们检验了Bychowsky和Nagibina（1978年）所定义的锚首虫科以及Kritsky和Boeger（1989年）所定义的锚首虫亚科的分类地位。在指环虫亚目内，双身虫科和指环虫科在最大似然法和最大简约法分析中得到了有力支持，但它们与拟默里吸虫科的系统发育关系仍未解决。伪指环虫亚科、锚首虫亚科、锚盘虫亚科和指环虫亚科之间的系统发育关系表明，Bychowsky和Nagibina（1978年）所定义的锚首虫科是并系的。最近被视为Kritsky和Boeger（1989年）所定义的指环虫科的物种组包括两个姐妹群。第一组包括淡水锚首虫亚科和锚盘虫亚科。第二组包括伪指环虫亚科、指环虫亚科以及来自黄斑蓝子鱼和黑斑叉鼻鲀的锚首虫亚科。Kritsky和Boeger（1989年）之前利用形态特征提出的锚首虫亚科的非单系性（即最近被视为锚首虫亚科成员的物种组的非单系性）表明，指环虫科的分类需要修订。
