Species not formally described.
[Only one cell observed.] Cell body 2.8 µm diameter. Body scales of 1 type: plate scales circular, 0.6 µm diameter, with a thickened rim and c. 24 radiating striae.
Southern Ocean, south of Australia, 52.01°S 134.05°E.
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.
