Description:

Metopion fluens Larsen and Patterson, 1990. The cell outline is ovate. Cells are 4 to 9 microns long, laterally compressed and with a small rostrum anterior to the flagellar insertion. Small bodies are seen in the protrusion or at the proximal anterior part of the cell. Two flagella of unequal size emerge from a ventral groove located in the left side of the cell. The long flagellum is about 1.5 times cell length, is thickened and is not tapered at the tip, and the short flagellum may be difficult to see. There are small granules in the posterior part of the cell. The nucleus is situated near the groove. The cells move by gliding.
