Haeckel, 1862, emend. Sanfilippo and Riedel, 1980
Latticed discoidal or lenticular shell enclosing a single or double medullary shell, and surrounded by an equatorial zone of spongy or concentrically-chambered structures (lentelliptical shell), or forms with an ellipsoidal cortical shell equatorially constricted enclosing a single or double medullary shell (D. tetrathalamus intro). The formerly actinommid subfamily Artiscinae was transferred to the Coccodiscidae by Sanfilippo and Riedel (1980) due to its phylogenetic affinities with extinct coccodiscids.
The following species of this family are treated in the present volume:
Didymocyrtis tetrathalamus
Spongoliva ellipsoides
