Cell outline oblong to ovate, 32±53 Mm long, 22±27 Mm wide, with slightly thickened pellicle. About 16 wide longitudinal striations occur on both faces of the cell and slightly follow a S-helix. Dorsal striations are more distinct than ventral ones. The anterior ¯agellum is as long as the cell and beats with a sweeping motion. The posterior ¯agellum is approximately 3 times the cell length, is thicker than the anterior ¯agellum and emerges as a hook from the ¯agellar pocket which is in the left-hand side of the cell. The ingestion apparatus has two rods but may be di cult to see. It extends halfway down the cell. This species consumed diatoms as long as 16 Mm. The nucleus is usually in the right posterior end of the cell but may be in the left-hand side. Moves by gliding and may undergo squirming movements. When changing direction, cells jerk backwards and then continue to move forward. Three cells observed.

One cell observed had its nucleus in the left-hand side of the cell, thus we suspect that the position of a nucleus is not a good diagnostic character.
