Kipferlia bialata ( Ruinen 1938) Kolisko et al. 2010 ( Fig. 4b View Fig )

Observation: Cell outline is kidney-shaped. Cells are 6 to 14 µm long (mostly 9 to 12 µm), not rigid, and with a longitudinal ventral groove. A membrane moves down along the groove. Two flagella emerge from the anterior part of the cell; the anterior flagellum bends backwards, is about the length of the cell and beats over the cell with a slow sweeping motion. The acronematic posterior flagellum beats asymmetrically and is about 1.5 times cell length. The posterior flagellum may vibrate actively in the groove when not beating. The cells consume bacteria, and food materials are transferred by the moving membrane to the back of the cell. The cells may have many food vacuoles and attach to the substrate with the tip of the posterior flagellum. The cells move slowly by skidding or gliding with the anterior flagellum beating with a flicking motion. Commonly observed in late cultures.

Remarks: This species was originally described by Ruinen (1938) as Cryptobia bialata from Australia with biflagellated protist having a ventral groove and an undulating membrane, but was transferred to Carpedimonas by Lee and Patterson (2000) because it has many similar characters to Carpediemonas . Recently Kolisko et al. (2010) created a genus ( Kipferlia ) for this taxon on the basis of molecular and ultrastructural studies. Previous authors reported the species to be 6–14 µm long. This species resembles Ergobibamus cyprinoides Park et al. 2010 and other Carpediemonas -like organisms presented by Kolisko et al. (2010) in that they are bean-shaped, have two flagella, and a conspicuous ventral groove. They may be not easily distinguished by light microscopy. For further discussion see Kolisko et al. (2010) and Park et al. (2010).
