本文报道了4种寡毛类纤毛虫，Dragescoi sp. n.，詹氏假单胞菌（Xu et al.2009）comb.n.，和P. kahli（Xu et al.2009）comb. n.，基于活体观察、蛋白银染色材料和SSU rRNA基因序列描述或重新描述。本文报道了一个新种：拟椭圆链霉菌P. paraellipticum sp. n.其特征为倒卵圆形细胞，口前区由17-21个领、9-11个颊和2个趋触膜组成，外泌体沿着带状运动排列。新种P. dragescoi sp. n.与其同类物的区别在于其倒卵细胞形状和缺乏趋触膜。基于原始切片中可识别的纤毛模式，Omegastrombidium jankowskii Xu et al.2009和O. kahli Xu et al. 2009应将其转移至Aegatha 2004属。基于SSU rRNA基因序列数据的系统发育分析表明，所有四个新的序列聚类与以前描述的同源物。该属被分为两个集群，这表明它的非单系性，可能对应于Agatha和Strüder-Kypke（2014）提出的两个亚属，以及它们的形态差异（细胞背腹扁平与不扁平）。
The morphology and phylogeny of four oligotrichid ciliates, Parallelostrombidium paraellipticum sp. n., P. dragescoi sp. n., P. jankowskii (Xu et al. 2009) comb. n., and P. kahli (Xu et al. 2009) comb. n., are described or redescribed based on live observation, protargol stained material, and SSU rRNA gene sequences. The new species P. paraellipticum sp. n. is characterized by its obovoidal cell shape, adoral zone composed of 17–21 collar, 9–11 buccal, and two thigmotactic membranelles, and extrusomes attached in one row along the girdle kinety. The new species P. dragescoi sp. n. is distinguished from its congeners by its obovoidal cell shape and a lack of thigmotactic membranelles. Based on ciliary patterns recognizable in the original slides, Omegastrombidium jankowskii Xu et al. 2009 and O. kahli Xu et al. 2009 should be transferred to the genus Parallelostrombidium Agatha 2004. Phylogenetic analyses based on SSU rRNA gene sequence data demonstrate that all four new sequences cluster with previously described congeners. The genus Parallelostrombidium is separated into two clusters, suggesting its non‐monophyly and probably corresponding to the two subgenera proposed by Agatha and Strüder‐Kypke (2014), as well as their morphological difference (cell dorsoventrally flattened vs. unflattened).
