Diagnosis Colonial, massive or knobby, plocoid. Gemmation due to extracalicinal budding. Corallites united by a granulate peritheca. Costosepta radial, granular laterally, compact, in the costal area dissociating into trabecular structures. Septal margins beaded. Peritheca tabulo-columnar. Small trabecular–lamellar columella. Endothecal dissepiments thin and subtabulate, abundant. Wall septoparathecal. Septal microstructure consisting of simple trabeculae forming dark axial lines. [details]

Remark In many respects the genus Paraplacocoenia Beauvais resembles the genus Haldonia. However, very granulate peritheca, dissociating into trabecular structures in the costal area and a lamellar columella are present in Paraplacocoenia but not in Haldonia. Furthermore, based on closely corresponding features, the genus Paraplacocoenia was merged with the Neocoenia as the subgenus of the latter (Baron-Szabo, 2014). Also see information under Hyndophorposis Soehle, 1899. [details]
