A small group of Tithonian planktonic ciliates, little-known in the area of the Polish Outer Carpathians, has been recorded in exotic limestones from the western part of the Silesian Nappe. Eleven species of the family Chitinoidellidae Trejo, 1975, belonging to the genera Chitinoidella, Daciella, Dobeniella, Longicollaria and Popiella are described here. The majority of studied samples have been assigned to the Boneti Subzone of the Chitinoidella Zone. Exotics with chitinoidellids represent environments which can be interpreted as platform margin reefs, slope of platform and inner platform.
