Description Massive to ramose cerioid subthamnasterioid corallum. Corallite polygonal in outline, intercalicinal increase Radial elements confluent, compact, bent at the place of the wall, septa of small size order contratingent. Distal edge with equal regular teeth, inner edge not observed, lateral faces not observed, pali present as small relieves and thickenings at the place of anastomoses. The two crowns initially described by Etallon were not seen. Microstructure unknown in the type species. Hexameral symmetry, no bilateral symmetry. Endotheca not observed , columella styliform, synapticulae probably absent, wall often not observed distally (subthamnasterioid pattern), of unknown nature. [details]

Comparison Relationships with Allocoenia created in 1859 still need to be clarified. Actinastrea, based on a Cretaceous species, has been widely merged (Geyer 1955a) with the group Allocoenia-Stephanastrea but is probably different by the nature of the wall. Enallocoenia needs the designation of a neotype to be compared Coenastrea has no palis Allocoeniopsis is probably a junior synonym. Chondrocoenia has a tendency to be plocoid and costae have bigger trabeculae than septa. [details]Description Massive to ramose cerioid subthamnasterioid corallum.
