As noted by Cros and Fortuño (2002), this species is similar to C. heimdaliae, which, however, has coccoliths with higher covers, wider openings and crystallites arranged in a hexagonal meshwork pattern.
Distinguishing features:
Parent taxon (convex): Holococcoliths with tube, covered distally by a convex cover
This taxon: Low wall with domal cover, ring of small perforations at base of cover and an apical perforation
