本文以中国青岛黄海沿岸沙样中分离到的厌氧纤毛虫Plagiopyla ovata Kahl， 1931为研究对象，对其形态和分子系统发育进行了研究。详细的口腔纤毛是首次记录到我们的知识和一个改进的物种诊断给出。对小亚单位核糖体RNA （SSU rRNA）基因进行了新测序，系统发育分析表明，卵形拟羽翼蝗属单系统科。然而，由于采样不足、缺乏已知物种的序列数据以及基因树中低节点支持或不稳定的拓扑结构，Plagiopylidae科和Plagiopyla属的进化关系仍然不清楚。本文还提供了一种鉴定具有有效发表名称的翼蝗属物种的钥匙。
The morphology and molecular phylogeny of Plagiopyla ovata Kahl, 1931, a poorly known anaerobic ciliate, were investigated based on a population isolated from sand samples collected from the Yellow Sea coast at Qingdao, PR China. Details of the oral ciliature are documented for the first time to our knowledge and an improved species diagnosis is given. The small subunit ribosomal RNA (SSU rRNA) gene was newly sequenced and phylogenetic analyses revealed that P. ovata clusters within the monophyletic family Plagiopylidae. However, evolutionary relationships within both the family Plagiopylidae and the genus Plagiopyla remain obscure owing to undersampling, the lack of sequence data from known species and low nodal support or unstable topologies in gene trees. A key to the identification of the species of the genus Plagiopyla with validly published names is also supplied.
