Neobodo saliens ( Larsen and Patterson 1990) Moreira et al. 2004 ( Figs 2l , 3j )

Cells are 4–12 μm long, elongate elliptical and somewhat inflexible. Two flagella of unequal in length emerge subapically form a shallow pocket. The anterior flagellum seems to be inactive, along the cell and helds forward with a single anterior curve. The acronematic posterior flagellum is typically directed straight behind the cell and is 2.2–3.5 times longer than the cell length. The cells swim in straight lines with rapid darts as mentioned elsewhere. Description based on observations of 20 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 saliens is distinguished from other species of the genus Neobodo by its rapid darting movement and the unique posterior flagellum directed in a straight line while swimming. This species is similar to Neobodo curvifilus , but is easily distinguished by the unique paddling anterior flagellum of N. curvifilus , which is curved along its entire length. Neobodo saliens also differs from Neobodo designis . Neobodo designis has both an anterior flagellum which coils up around the anterior part of the cell and a posterior flagellum, which has a sinuous form while swimming. Neobodo saliens has an anterior flagellum held forward, curved back at the tip with an angle and a posterior flagellum directed straigth behind the cell. While swimming, N. designis rotates around its longitudinal axes, whereas N. saliens makes sudden darts in a straight line. This species appears to be cosmopolitan.
