Abstract

Three cyrtophorian ciliates isolated from brackish biotopes in China, sp. nov., Foissner, 1988 and Foissner, 1981 , were investigated using living observation and protargol-staining methods. sp. nov. can be characterized as follows: cell size 50–70 × 30–40 μm ; body oval with posterior end rounded; four tetragonally positioned contractile vacuoles; 12–15 nematodesmal rods; five right and six left somatic kineties; terminal fragment positioned apically on dorsal side, consisting of 11–14 basal bodies; four or five fragments in preoral kinety. and were generally consistent with previous descriptions. In addition, a brief revision and a key to are presented. The small-subunit (SSU) rRNA gene was also sequenced to support the identification of these species. Phylogenetic analyses based on molecular data indicate that the genera and are closely related and both are well outlined; that is, all known congeners for which SSU rRNA gene sequence data are available group together, forming the core part of the family Chilodonellidae.
