Abstract:
:The morphology and infraciliature of two pleurostomatid ciliates, Amphileptus aeschtae nov. spec. and Amphileptus eigneri nov. spec., collected from shrimp-culturing ponds of the Bohai Sea, China, were investigated using live observations and the protargol impregnation method. The new species A. aeschtae is identified by the presence of 200-300 macronuclear nodules and several contractile vacuoles along the ventral side of the cell. A. eigneri differs from its congeners, inter alia, by the marine habitat, the presence of many contractile vacuoles along the ventral margin and the number of somatic kineties on both sides. Loxophyllum ozakii Shigematsu, 1953 is transferred to Kentrophyllum.
