الوصف:

Anisonema ovale Klebs, 1893. Cells are oval, rigid and measure 11 microns long and 7 microns wide. The cell surface is smooth. The anterior flagellum is about the cell length and the posterior one is 1.5 times the cell length. Looks like Protaspis tegere and further study may reveal that this is not really an Anisonema.
