Abstract

The morphology of two new scuticociliates, sp. nov. and sp. nov., isolated from a mangrove wetland in Shenzhen, PR China, was studied using live observation and the protargol impregnation method. is characterized by a body size of about 20–35×10–15 µm , a partly two-rowed membranelle 1, and 12 or 13 somatic kineties. is distinguished by a membranelle 1 comprising two longitudinal rows of basal bodies. Three populations are suggested as subjective synonyms of the new species. Improved diagnoses of the genus Kahl, 1926 and its type species Kahl, 1926 are provided. Results of phylogenetic analyses based on 18S rRNA gene and ITS1-5.8S–ITS2 region sequences indicate that is most closely related to , while the closest relative of is .
