Phylogenetic analyses of a range of gorgoderid trematodes based on ITS2 and partial 28S rDNA data lead us to propose the Degeneriinae n. subfam. for the genus Degeneria in recognition of its phylogenetic isolation and distinctive morphology and biology. The current concepts of the subfamilies Anaporrhutinae and Gorgoderinae were supported. Within the Gorgoderinae, the large genus Phyllodistomum is shown to be paraphyletic relative to Pseudophyllodistomum and Xystretrum. Notably, the clade of marine Phyllodistomum does not form a clade with the other marine genus, Xystretrum. Distinct clades within the Gorgoderinae correspond variously to identity of first intermediate host, form of cercaria and their marine or freshwater habitat. We are not yet in a position to propose separate genera for these clades.
基于 ITS2 和部分 28S rDNA 数据对一系列戈尔戈德里（Gorgoderid）吸虫的系统发育分析，使我们提出了 Degeneriinae n. 亚科，以承认 Degeneria 的系统发育隔离及其独特的形态和生物学特征。目前的 Anaporrhutinae 和 Gorgoderinae 亚科概念得到了支持。在 Gorgoderinae 内，大型属 Phyllodistomum 相对于 Pseudophyllodistomum 和 Xystretrum 显示出并系关系。值得注意的是，海洋 Phyllodistomum 的分支与另一个海洋属 Xystretrum 没有形成分支。Gorgoderinae 内的不同分支对应于第一中间宿主的同一性、尾蚴的形式及其海洋或淡水生境。我们还没有为这些分支提出单独的属。
