Citation: Ericiolus frigidus Thomsen in Thomsen et al., 1995
taxonomic rank: Species
Synonyms: ‘Coccolithophorid sp. 2’ in Thomsen et al. 1988

Distinguishing features:
Parent taxon (Ericiolus): Nannoliths, miniscule (<1 µm), formed of 3 nearly co-planar rays, often with a distal process. Cells monomorphic, often saddle-shaped, with long flagella and haptonema.
This taxon: All four spikes of tetrad of similar length (0.2-0.3 µm) and angles between all four are equal.
