Description

This genus is characterised by slits in the distal shield, sometimes referred to as “T” elements.

Three morphotypes were recognised by Young & Westbroek (1991), and an additional morphotype appears to be present in the Southern Ocean:

Type A (huxleyi): Coccoliths 3-4 μm; distal shield elements robust; central opening covered by a grill.
Type B (pujosae): Coccoliths 3.5-5 μm; distal shield elements delicate; central area covered with lath-like elements.
Type C (kleijneae): Coccoliths 2.5-3.5 μm; distal shield elements delicate; central area open or covered by a thin plate.
Type B/C: Coccoliths 3-4 μm; distal shield elements delicate; central area open or covered by a thin plate. This is similar in morphology to Types B and C but is intermediate in size. This form dominates assemblages in the Southern Ocean (Hockfield, 2000; Findlay & Giraudeau, 2000).
