Notes
A colorless freshwater amoeboid flagellate, T. seravini sp. n., is described. The cell measures 9.9-16.5x6.6-11.6 µm; cysts diameter is 8.3-11.6 µm. Cell body flattened. Locomotory flagellum short, posterior flagellum two times body length. Two contractile vacuoles have a common canal. A large nucleus is situated anteriorly. Cytoplasm contains many large granules. Somatic scales are trianguar, base length is 0.7 µm; they are perforated along the edge. Plasmodia form as a result of a disruption of cytokinesis and cell fusion. T. seravini differs from other related species in size and body shape, in the granular cytoplasm and the shape of the scales.
