Abstract

Oligotrich ciliates are common members of marine microplankton. However, their biodiversity is not well documented. In this study, the morphology and phylogenetic positions of three new oligotrich species, spec. nov., spec. nov. and spec. nov., collected from coastal habitats of southern China, were investigated. is characterized by the girdle kinety which encircles the cell twice as two dextrally oriented whorls with some undulations and by the presence of several macronuclear nodules. is recognized by the girdle kinety encircling the cell as two dextrally oriented whorls and extrusomes arranged in a stripe along the girdle kinety. differs from its congeners by the obconic body shape and the posterior portion of the girdle kinety extending downwards on the left ventral side to reach the posterior pole. In small-subunit rRNA gene trees, clusters with and , and is sister to the clade containing , and sp.
