Two new marine scuticociliates, Pleuronema sinica n. sp. and P. wilberti n. sp., collected from the sand beach of Qingdao, China, were investigated in vivo and following protargol impregnation. Ciliates of the genus Pleuronema are normally recognizable by their large sail-like paroral membrane although one species, P. grolierei, has shorter cilia in the paroral membrane. Neither of the new forms has the conspicuous paroral membrane in vivo so in this respect they are not typical members of this genus. Pleuronema sinica is characterized by its large, conspicuously flattened body, the possession of only one preoral kinety, the irregular-shaped macronucleus and the rather unusual structure of the oral apparatus. By contrast P. wilberti has a medium-size broad-oval body, six to eight preoral kineties and a highly differentiated membranelle 3 that is five- or six-rowed. An identification key is supplied for the 15 species of Pleuronema for which the infraciliature is known.
对采自中国青岛沙滩的两种新的海洋盾纤毛虫——中华侧口虫（Pleuronema sinica）新种和威尔伯侧口虫（P. wilberti）新种进行了活体观察和蛋白银染色观察。侧口虫属的纤毛虫通常可通过其大的帆状口侧膜识别，尽管有一种格氏侧口虫（P. grolierei）的口侧膜纤毛较短。这两种新形态的纤毛虫在活体中均无明显的口侧膜，因此在这方面它们并非该属的典型成员。中华侧口虫的特征在于其大且明显扁平的身体、仅具有一列口前动纤毛、不规则形状的大核以及颇为独特的口器结构。相比之下，威尔伯侧口虫具有中等大小的宽椭圆形身体、六至八列口前动纤毛以及高度分化的五或六排的第3小膜。文中提供了已知纤毛下器的15种侧口虫的检索表。
