Classification: ntax_cenozoic -> Isochrysidales -> Isochrysidaceae -> Isochrysis -> Isochrysis nuda
Sister taxa: I. galbana, I. litoralis, I. maritima, I. nuda

Taxonomy:

Citation: Isochrysis nuda Bendif & Probert, in Bendif et al. 2013

Rank: Species

Distinguishing features: Dominant stage non-motile, without body scales

Original description: Cells solitary, non-motile, spherical (3.5–6 µm in diameter), without scales. Flagella two, slightly unequal (7.5–9 µm) inserted apically with abbreviated haptonema (100 nm) between; latter with three to four microtubules in the emergent part. Plastid single, parietal, yellow-brown with immersed pyrenoid. Asexual reproduction by division in motile stages. Nucleotide sequences of nuclear SSU and LSU rDNA and cox1 gene are distinctive. Substitutions in nuclear SSU rDNA sequence at positions 216 (C/T), 706 (T/C), 1329 (C/T), 1348 (T/C), 1667 (T/C) and 1668 (C/T) are diagnostic compared to other species members of Isochrysis.
