Description

[Only one cell observed.] Cell body 3.7 µm diameter; flagella and haptonema not seen. Body scales of 4 types: large spine scale base circular, c. 1 µm diameter, with an upwardly flexed rim, spine 10 µm long overall; small spine scale base elliptical, 0.4 × 0.4 µm, with a distinct rim, spine 0.35 µm long; large plate scale elliptical to circular, 1.1 × 1.6 µm, distal surface with c. 90 fine radiating striae, proximal surface with an interwoven fibrous pattern; small plate scale elliptical to circular, 0.4 × 0.5 µm, distal (outer) surface with c. 68 fine radiating striae and 2 off-centre holes, proximal (inner) surface with a distinct rim, an interwoven fibrous pattern and 2 off-centre holes.

Distribution

Southern Ocean, south of Australia, 46°24.7’S 139°21.6’E.

Comments

Chrysochromulina genus description: Cells have homodynamic flagella and a coiling haptonema, and electron microscopy is usually required to identify the species. As well as being photosynthetic, these fragile haptophytes ingest picoplanktonic and nanoplanktonic organisms by phagocytosis.
