Distinguishing features:
Parent taxon (Pappomonas): Coccolith distal rim serrated - elements pentagonal;
Coccosphere dimorphic or trimorphic. Processes only on CFCs coccoliths. Calices with 2-fold symmetry
BCs without axial spine or node
This taxon: CFCs with axial cross, spine and flat calyx of two similar, diverging blades each with central rod
BCs with 5 longitudinal bars and one crossbar
AACs like CFCs but with lower spine and smaller clayx, may occur around coccosphere
