RT Journal Article T1 Two Anaerobic Ciliates (Ciliophora, Armophorea) fromChina: Morphology and SSU rDNA Sequence, with Reportof a New Species, Metopus paravestitus nov. spec A1 Song, Li A1 Wenbao, Zhuang A1 Pérez Uz, María Blanca A1 Qianqian, Zhang A1 Xiaozhong, Hu AB The morphology and phylogeny of two metopid ciliates, collected from anaerobic habitats in China, were investigated using live observation, protargol staining method, and SSU rDNA sequencing. The new species Metopus paravestitus nov. spec. can be distinguished by a combination of the following features: oblong cell with densely arranged ectobiotic prokaryotes perpendicular to cell surface, filiform intracytoplasmic structures packed in the anterior portion of the cell. Our work also demonstrates the wide geographical distribution of Metopus es (Muller, 1776) Lauterborn, 1916. The order Metopida is € consistently depicted as a paraphylum in SSU rDNA phylogeny. Metopus paravestitus nov. spec. is closely related to its marine congeners than to freshwater forms. The present study confirms once again the non-monophyly of the genus Metopus and genus Metopidae.
