Four colonial sessile peritrichs were discovered during a survey of ciliate diversity of coastal waters of the Yellow Sea, Shandong Province, China. Following studies of their living morphology, infraciliature and silverline system, three were identified as new members of the generaPseudepistylisandZoothamnium. Pseudepistylis paramphoran.sp. is the second species assigned to the genus, which is characterized by its rigid, dichotomously branched stalk, reticulate silverline system and marine habitat.Zoothamnium paraniin. sp. was isolated from brackish water andZ. hartwigin. sp. was collected from marine water.Zoothamnium paraniiis characterized largely by its highly variable zooid size and having an extremely long infundibular polykinety 3.Zoothamnium hartwigiis separated from its congeners by having two types both of peristomial lip and infundibularpolykinety 3. We also supply supplementary morphometric data and photomicrographs ofEpicarchesium variabilebased on examinations of specimens in vivo and after silver staining.

Fig.2.Zoothamnium paraniin. sp. from life (A, B, D–G, K, L) and after staining with protargol (C, H) and silver nitrate (I, J).A,F–G,L–living zooids at high magnification;B, D, E–colony form in vivo;C–entire oral infraciliature in ventral view, arrow marks epistomial membrane and arrow with umerals indicates numbering convention for polykineties and rows of kinetosomes within each polykinety;H–detailed arrangement of infundibular polykineties;I,J–silverline system;K– living zooid at high magnification focused to show the pellicular striations. G, germinal kinety; H, haplokinety;

P 1–3, infundibular polykinety 1–3; Po, polykinety. Scale bars: 40 μm in A, F, G;100 μm in B, E.
