title: Taxonomic characterization of two marine peritrichous ciliates, Pseudovorticella clampi n. sp. and Zoothamnium pararbuscula n. sp. (Ciliophora: Peritrichia), from North China.
abstract: The morphology, infraciliature, and silverline system of two new peritrichous ciliates, Pseudovorticella clampi n. sp. and Zoothamnium pararbuscula n. sp., have been investigated based on both living and silver-impregnated specimens. Partial sequence of 18S-ITS1-5.8S rDNA of Z. pararbuscula is also determined in order to compare it with the closely related congener, Zoothamnium arbuscula. Zoothamnium pararbuscula can be distinguished from its close form Z. arbuscula by the different habitats, the appearance of the main stalk, the position of the contractile vacuole, and the information derived from 18S-ITS1-5.8S rDNA sequence analysis. Pseudovorticella clampi n. sp. is distinguished from its congeners by its body shape and size, pellicle granules, habitat, and number of transverse silverlines.
