Frontonia anatolica n. sp., a new peniculid ciliate (Protista, Ciliophora) from Lake Van, Turkey

The morphology, ciliature, and silverline system of a new ciliate, Frontonia anatolica n. sp., isolated from the bottom sediment of the eastern shore of Lake Van, a large alkaline lake in Eastern Anatolia Turkey, were investigated using live and silver impregnation methods. Frontonia anatolica n. sp. is characterised by an elliptical body shape; by an in-vivo body size of 101–134 × 47−67 μm; by dorsoventral flattening of about 2:3 to 1:2; by 2 contractile vacuoles located in the anterior and posterior body parts, each with 6–7 collecting canals and 1 excretory pore; by about 93 somatic kineties; by 3 vestibular and 3–5 postoral kineties; and by peniculi 1 and 2 each having 4 ciliary rows, and peniculus 3 having 2 ciliary rows.
