Ciliates of the genus Pleuronema are a speciose and ubiquitous group. Recent studies suggest that there may be a sizable amount of undiscovered species diversity. In the present study, two new Pleuronema species have been isolated from the subtropical coastal waters of China and characterized using morphological and taxonomical methods: Pleuronema pulchra n. sp. is characterized by a body size of 75–90 × 25–40 µm in vivo , 32–...

During a study on the diversity of ciliated protists in Lake Weishan Wetland, the largest wetland in northern China, four epibiotic sessilid peritrichs were isolated from aquatic host animals. Two of them, i.e., Epistylis cambari Kellicott, 1885 and Epistylis lwoffi Fauré-Fremiet, 1943, were known species whereas the other two, i.e., Parapiosoma typicum gen. nov., sp. nov. and Orborhabdostyla gracilis sp. nov., are new to scie...
