Description:

Discocelis (disco-see-liss) saleuta V+rs, 1988. Cells are about 3.5 - 6.5 microns long, disc-shaped, flattened, anteriorly concave and posteriorly convex. Two flagella emerge from a depression on the anterior margin of the cell. The recurrent flagellum trails behind the gliding cell and is slightly longer than the cell. The shorter flagellum is less than 1 microns long, is hard to see and is inactive. The nucleus is located anteriorly in the right half of the cell. There is a line of bodies around the margin of the cell. The cells glide smoothly in closely contact with the substrate.
