与其钙化的姐妹群Cheilostomata相比，未钙化的栉口苔藓虫表现出相对简单且往往不一致的形态，使其特别适合使用分子工具来划分物种并研究它们之间的相互关系。泡囊藻科由6个属组成，其中3个属，Zoobotryon，Avenella和Watersiana是单型的，而一个，Vesicularia，包括4个种。然而，大多数囊泡虫多样性存在于Amathia（39种）和Bowerbankia（21种）中。Amathia和Bowerbankia各自的单系地位最近受到分子证据的质疑，并在本研究中进一步研究。多基因（ssrDNA，rrnL，cox 1）系统发育分析显示，Bowerbankiais并系于Zoobotryon和Amathia，后者被解析为非单系。尽管在一些分析中，泡囊藻也嵌套在这种并系组合中，但贝叶斯拓扑检验不支持这一结果。我们的研究结果进行了讨论的范围内发表的形态证据，并导致的结论，即Bowerbankia和Zoobotryon应被归类为初级主观同义词的Amathia。提供了修订的命名法。此外，我们还研究了广泛分布的假定同种物种之间的遗传差异，并发现了外群分类单位Anguinella palmata和Bowerbankia citrina，Amathia vidoviciandAmathia crispa中可能的隐藏多样性。
Compared to their calcified sister group, order Cheilostomata, uncalcified ctenostome bryozoans exhibit relatively simple and often inconsistent morphologies, making them particularly suitable candidates for the use of molecular tools to delimit species and examine their interrelationships. The family Vesiculariidae is composed of six genera, three of which,Zoobotryon,AvenellaandWatersianaare monotypic, and one,Vesicularia, encompasses four species. The majority of vesiculariid diversity, however, is found inAmathia(39 species) andBowerbankia(21 species). The respective monophyletic status forAmathiaandBowerbankiahas recently been put into question by molecular evidence and is being further examined in this study. Multigene (ssrDNA,rrnL,cox1) phylogenetic analysis revealed thatBowerbankiais paraphyletic to the inclusion ofZoobotryonandAmathia, where the latter was resolved as non‐monophyletic. AlthoughVesiculariaalso nested within this paraphyletic assemblage in some of the analyses, Bayesian topology testing did not support this result. Our results are discussed within the context of published morphological evidence and lead to the conclusion thatBowerbankiaandZoobotryonshould be classified as junior subjective synonyms ofAmathia. A revised nomenclature is provided. Furthermore, we examined genetic divergences between widely distributed supposed conspecific species and discovered possible cryptic diversity in the outgroup taxonAnguinella palmataand inBowerbankia citrina,Amathia vidoviciandAmathia crispa.
