Sister taxa: I. galbana, I. litoralis, I. maritima, I. nuda

Taxonomy:

Citation: Isochrysis litoralis Billard & Gayral 1972
Rank: Species

Distinguishing features: Dominant stage non-motile, one type of body scales

Original description: Young cells non-motile, hemispherical (4-6 x 6-8 µm) or round (5µm); older cells spherical varying in size (5-15µm) with thick pectic envelopes not easily penetrated by stains. Two parietal golden-yellow chromatophores with one intraplastidial pyrenoid per chromatophore. Asexual reproduction by division of the non-motile cells and by production of elongated swarmers (4 x 7µm) with two apical subequal (7-8 and 8-9µm) homodynamic flagella. Swimming movements similar to those of Isochrysis maritima. Cells covered with one layer of oval plate scales (0.3 x 0.18µm) with a thickened margin and radiating ridges.
