Carpediemonas membranifera Ekebom et al. 1996 ( Fig. 4a View Fig )

Observation: Cells are elliptical or obovate and 3 to 6 µm long with a longitudinal ventral groove, which extends most of the cell length. Two flagella of unequal length emerge from the anterior distal part of the cell. The anterior flagellum is bent over backwards and is as long as the cell and beats stiffly. The acronematic posterior flagellum is 2.5 to 4 times cell length, beats actively in the ventral depression and usually lies in the groove. The cells usually move by skidding with the anterior flagellum beating with a stiff paddling motionThe cells consume bacteria. Commonly observed in anoxic conditions.

Remarks: This species has been described from marine sites in subtropical and tropical Australia, Brazil and Korea, and previously reported cell lengths are 3 to 9 µm ( Larsen and Patterson 1990, Ekebom et al. 1996, Simpson and Patterson 1999, Bernard et al. 2000, Lee and Patterson 2000, Al-Qassab et al. 2002, Lee 2002b). This species is distinguished from Kipferlia bialata by its smaller size, the absence of the moving membrane and the relatively long posterior flagellum. It consumes bacteria ( Larsen and Patterson 1990, Ekebom et al. 1996, Lee and Patterson 2000) and usually occurs in large numbers with Cafeteria marsupialis and Kipferlia bialata ( Lee and Patterson 2000) .
