Morphology:
Motile cells are ovate with a parietal brown-green plastid. The anterior flagellum is hairy and is covered by clavate knob scales and the posterior flagellum with a slight distal attenuation is naked. Cells are sometimes elongate. A layer of eyespot globules is present on the external face of the plastid, near the flagellar insertion. A pyrenoid is not present. The plastid presents a simple parallel arrangement of thylakoid lamellae. A pulsate vacuole seems to be connected to the flagellar pit. [Bendif et al. 2011]
