The phylogenetic analysis of the 16 recognized genera in the Bunocotylinae, based upon 30 morphological transformation series, produced 2 most parsimonious trees, each with a consistency index of 0.62. The monophyly of the group is supported by 6 synapomorphies. Ahemiurus, Aphanuroides, Aphanurus, Myosaccium, and Indoderogenes separate independently in the basal part of the tree. Saturnius and Bunocotyle separate next, forming a clade. Machidatrema, Duosphincter, Theletrum, and Monolecithotrema separate independently; and in the most derived part of the tree Opisthadena + Neopisthadena + Mitrostoma, Genolinea, and Neotheletrum grouped together form a clade. Optimization of hosts and geographic distribution onto the 2 most parsimonious trees suggests that the bunocotylines originated from an ancestor that was host specific to fishes of the Clupeidae and was distributed in the Tethys Sea.
基于30个形态转变系列，对Bunocotylinae亚科中16个已确认属进行的系统发育分析产生了2棵最简约树，每棵树的一致性指数为0.62。该类群的单系性由6个共衍征支持。Ahemiurus、Aphanuroides、Aphanurus、Myosaccium和Indoderogenes在树的基部独立分支。Saturnius和Bunocotyle接下来分支，形成一个分支。Machidatrema、Duosphincter、Theletrum和Monolecithotrema独立分支；在树的最衍生部分，Opisthadena + Neopisthadena + Mitrostoma、Genolinea和Neotheletrum聚在一起形成一个分支。将宿主和地理分布优化到这2棵最简约树上表明，Bunocotylinae亚科起源于一个宿主专一为鲱科鱼类且分布于特提斯海的祖先。
