Taxonomic characterization of Vorticella fuscaPrecht, 1935 and Vorticella parapulchella n. sp., two marine peritrichs (Ciliophora, Oligohymenophorea) from China.
Two marine peritrich ciliates, Vorticella fuscaPrecht (1935) and Vorticella parapulchella n. sp. were discovered in the littoral zone of Qingdao, northern China. Their morphology, infraciliature, and silverline system were described using live observation and silver impregnation. The poorly known species V. fusca is redescribed, adding information about the oral infraciliature and pellicular morphology. Vorticella parapulchella n. sp. is superficially similar to Vorticella pulchellaSommer (1951) but is distinguished from it by being markedly smaller and having much more widely spaced pellicular ridges. The infundibular infraciliature of V. parapulchella is extremely unusual in having infundibular polykinety 3 reduced to two rows, one of which has almost disappeared.
