Neobodo designis (Skuja 1948) Vickerman 2004

( Figs 2n , 3i )

Cells are 4–7 μm long, somewhat flexible and usu- ally elliptical with two unequal flagella emerging from a subapical pocket. The anterior flagellum is about the length of the cell or slightly shorter and curved back over the rostrum. The anterior flagellum is fold- ing around the anterior part of the cell when the cell is feeding. The acronematic posterior flagellum is 2–4 times the length of the cell and somewhat curved while swimming. The nucleus is located close to the midline of the cell. The cells rotate around their longitudinal axes while swimming. Description based on observations of 22 cells. Occurance: every month at Acı Lake, temperature 1–23.5 °C, salinity, 24–67.5 psu, dissolved oxygen 3.75–13.2 mg /L.

Remarks: Neobodo designis has been characterized by the rotating behavior of swimming cells, but Neobodo cygnus reported by Patterson and Simpson (1996) and N. platyrhynchus reported by Lee and Patterson (2000) also have a rotating swimming movement. Neobodo cygnus may also wrap the anterior flagellum around the anterior end of the cells just like Neobodo designis , may be distinguished from N. designis by having a spiral groove. Further study is required to establish the identities of these taxa. This species has been reported from the world in marine and freshwater environments.
