Acanthoica quattrospina


Classification: Coccolithophores -> Syracosphaerales -> Rhabdosphaeraceae -> Acanthoica -> Acanthoica quattrospina
Sister taxa: A. quattrospina, A. acanthifera, A. acanthos, A. biscayensis, A. janchenii, A. maxima, A. sp A, A. backmanii, A. cohenii, A. laffittei, A. sp.,

Taxonomy:

Citation: Acanthoica quattrospina Lohmann, 1903
Rank: Species
Variants:
The following species were accepted by Kleijne (1992) in her review of the Rhbdosphaeraceae, but 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).

Ecology & Biogeography: A very widespread species, although rarely abundant. It is often present in low diversity assemblages such as those seen in shelf seas.

Biology & life-cycles: HOL = form with affinities to Sphaerocalyptra, not separately described (Cros et al. 2000). Very good combintion coccosphere examples were illustrated by Supraha (2014)
