Taxonomy:

Citation: Acanthoica quattrospina Lohmann, 1903
Rank: Species
Variants:
The following species are very rarely recorded and difficult to separate from A. quattrospina. It is possible that some of them are merely variants of A. quattrospina
Synonyms:

Distinguishing features: Body coccoliths sub-circular, (1.5-2.5 µm), with slits between radial cycle elements, lamellar cycle makes low cone. Long spines on polar coccoliths (one or both ends).
