Revision of the family Asteroseriidae (Anthozoa, Scleractinia, Cretaceous)

The Cretaceous coral family Asteroseriidae (suborder Fungiina) is revised on the basis of its type genus and respective type species. The family encompasses small solitary patellate corals with compact septa in a regular hexameral symmetry. Septa are made of large trabeculae expressed in a regularly ornamented upper septal margin and septal lateral face. Synapticulae are present. In addition to the name-giving genus Asteroseris de Fromentel, 1867, the genera Actinoseris d’Orbigny, 1849 and Microseris de Fromentel, 1867, from the Cretaceous of France are assigned to the family. All genera are revised on the basis of the types of their respective type species, as far as available. Possible species of all three genera are presented. The family ranges from Hauterivian to Cenomanian of the Tethys.
