molischii type XCs “undulating” planoliths, confined to imbricate circlet around flagellar pole. CFCs with spines showing calyx with 4-fold symmetry, AACs usually present.

Distinguishing features: Parent taxon (Syracosphaera): Coccospheres usually dithecate. Exothecal coccoliths (XCs) highly variable. Endothecal coccoliths are muroliths with 1, 2 or 3 flanges, the forms with 2 flanges are often placolith-like. This taxon: BCs placolith-like (i.e. with proximal and distal flanges), often with ridges and irregular central area calcification, no spines. XCs variable.
