Cell ovate, 35±45 Mm long, ¯attened, with a posterior point to the cell. Approximately 36 pellicular striations follow a S-helix. The striations of the ventral face are more distinct than the dorsal ones. The striations appear to overlap each other, with raised ridges being separated by ¯at regions. Some but not all cells have globular granules located along the grooves. This species is capable of squirming movements, but not vigorously so. The anterior ¯agellum is about the length of the cell and bends to the right while the cell is swimming. The posterior ¯agellum bends to the left while swimming, is slightly longer than the cell and is stronger than the anterior ¯agellum. The posterior ¯agellum is swollen near its base. The ingestion organelle has two conspicuous thick rods and extends to two-thirds of the length of the cell. Consumes diatoms, one cell containing diatoms up to 17 Mm long. The reservoir is pear-shaped and in the left half of the cell. The nucleus is about 15 Mm long and located in the left side of the cell near the midline. About 2 Mm size refractile bodies lie around the reservoir, ingestion organelle and nucleus. Cells move by skidding in close contact with the substratum. Four cells observed.
