This study investigated the morphology and molecular characteristics of three interesting free-living cyrtophorid ciliates, including two new species, isolated from China: Chilodonella parauncinata sp. n. can be identified by its elongated body shape, with a sharp protrusion in the left anterior part, cell size ca. 60x25m in vivo, five right and 6-7 left kineties with kinetosomes densely arranged, and a curved cyrtos. Chlamydonella irregularis sp. n. differs from its congeners by the oval body shape, cell size 50-60x25-40m in vivo, irregular shape of macronucleus, 30-40 club-shaped ventral protuberances, and 17 somatic kineties. Two isolates of Chlamydonella derouxi Song, 2003, collected from an intertidal area in Shandong and a mangrove wetland in Guangdong respectively, correspond well with two previous descriptions, but differ in comprising more basal bodies in left and right equatorial fragments and in having more finger-like protuberances on the ventral side. Phylogenetic analyses based on the small subunit rRNA gene sequences showed that C. parauncinata sp. n. clustered with Chilodonella uncinata, but was a well-outlined species of the genus, and C. irregularis sp. n. and C. derouxi grouped in the family Lynchellidae with their congeners to form the monophyletic genus Chlamydonella.
