Original description: Young cells non-motile, hemispherical (3 x 6 µm) forming cubic masses; older cells spherical (6 x 7 µm)surrounded by concentric pectic envelopes; two parietal yellow-green chromatophores present; one intraplastidial pyrenoid per chromatophore. Asexual reproduction by division of the non-motile cells and by production of elongated metabolic swarmers (3 x 4.5-5 µm) with two apical subequal (6 and 8 µm) homodynamic flagella; movement of the cells generally in a backward direction; a single chromatophore and a stigma. Cells covered with one layer of subcircular plate scales (0.16 x 0.14 µm) with a thickened margin and radiating ridges.
