Taxonomy:

Citation: Solisphaera galbula Kahn & Aubry, in Aubry & Kahn, 2007
taxonomic rank: Species

Distinguishing features:
Parent taxon (Solisphaera): Coccoliths without radial lath cycle; coccosphere dome-shaped, polymorphic
This taxon: dBCs with cylindrical protrusions not ending in papilla; CCs with low hump-backed protrusion; pBCs with ridged protrusion
