Lastly, based on analysis on phylogentic relationships among 39 ciliates combined with their main morphologic characters, some conclusion were drawn: 1 the monophyly of the peritrichs was strongly supported, and its subclass rank in the class Oligohymenophorea is reasonable; 2 the genus Epistylis might not be monophyletic, and the peristomial area, especially the peristomial lip, might be an important phylogenetic character within the genus Epistylis; 3 the taxonomic rank of the genus Carchesium and the genus Campanella were suggested to be adjusted; 4 Opisthonecta probably diverged from peritrichs with stalks; 5 the phylogenetic tree of peritrichs was reconstructed based on the molecular information inferred from SSrRNA gene sequences and the morphology.

测定了6科8属13种缘毛类纤毛虫的SSrDNA序列，将构建的最大简约树和邻接树与形态学相结合，分析得出：1）缘毛类纤毛虫是单系的，其分类地位是隶属于纤毛门寡膜纲缘毛亚纲：2）指出累枝虫属可能不是单系的，口围区是累枝虫属中重要的系统发育特征；3）建议调整独缩虫和聚钟虫属的分类地位；4）得出后游虫可能是由有柄缘毛类进化而来的类群；5）基于缘毛类反口区结构和SSrRNA基因序列提供的信息重建了缘毛类纤毛虫的系统发育树。
