Taxonomic and Phylogenetic Studies of Two Brackish Pleuronema Species (Protista, Ciliophora, Scuticociliatia) from Subtropical Coastal Waters of China, with Report of a New Species.

ABSTRACT: The genus Pleuronema Dujardin, 1841, with nearly 40 morphospecies, is one of the largest genera in the well-known subclass Scuticociliatia. In the present study, two Pleuronema species were collected from subtropical coastal waters of the East China Sea. The morphology and molecular phylogeny were investigated using modern standard methods. Pleuronema ningboensis n. sp. is mainly characterized by an elliptical body in outline with the right ventrolateral side straight, 16-22 somatic kineties, 3-5 preoral kineties, and the posterior end of the membranelle 2a hook-like. An improved diagnosis of Pleuronema orientale Pan et al., 2015 was provided: body size in vivo usually 90-135 × 45-85 μm, right ventrolateral side convex, 36-51 somatic kineties, 1-5 preoral kineti
