本文报道了三属10种壶腹类的新描述或新记录。根据这些信息，Lagenophryidae科由五个属组成：Lagenophrys，Paralagenophrys。隐齿龙属例如，在一个实施例中，Setonophrys和Operculigera。Lagenophryidae属间洛里卡孔和口围括约肌的大体结构不同，洛里卡的形状和附着于宿主的方式不是Lagenophryidae属间的特征。在三个最大的蜥蜴类属中，形状的差异仅仅是为了适应附着在宿主的不同部位。Usconophrys，以前在Lagenophryidae，和Cyclodonta被分配到Usconophryidae n。fam.，其特征在于具有洛里卡、缺乏由口缘括约肌操作的闭合装置以及具有盖状口缘。Lagenophrys，Setonophrys和Paralagenophrys似乎是从Operculigera内的祖先分别进化而来的。Lagenophryid洛里卡孔组成的相对的嘴唇可能演变为紧密的密封，以防止水分流失时，主机暂时离开水。Lagenophrys与其他Lagenophryid属相比具有更大的多样性和更广泛的分布，这可能是由于第二类分裂赋予的寄生宿主的优势。
Ten species of lagenophryid peritrichs in three genera are redescribed or described for the first time. Based on this information, the family Lagenophryidae was found to consist of five genera: Lagenophrys, Paralagenophrys. Clistolagenophrys n. g., Setonophrys, and Operculigera. Lagenophryid genera differ in gross structure of the lorica aperture and the peristomial sphincter associated with it. Shape of the lorica and mode of attachment to the host are not generic characteristics in the Lagenophryidae. Differences in shape evolved within each of the three largest lagenophryid genera merely as adaptations for attachment to different parts of a host. Usconophrys, formerly in the Lagenophryidae, and Cyclodonta are assigned to the family Usconophryidae n. fam., which is characterized by possession of a lorica, lack of a closure apparatus operated by the peristomial sphincter, and possession of an operculariform peristome. Lagenophrys, Setonophrys, and Paralagenophrys appear to have evolved separately and convergently from ancestors within Operculigera. Lagenophryid lorica apertures consisting of opposing lips probably evolved as tight seals to prevent water loss when the host is temporarily out of water. The greater diversity and wider distribution of Lagenophrys compared with other lagenophryid genera may result from an advantage in recolonizing hosts conferred by second-type division.
