Classification
Diagnosis
Subplocoid to fasciculate colony. Gemmation extracalicinal and extracalicinal-marginal. Costosepta porous to subcompact, compact in oldest cycles, with strongly beaded margins. Columella well-developed and spongy, or reduced. Endothecal dissepiments sparse. Synapticulae abundant. Wall parathecal-synapticulothecal.
Remarks
Neocoeniopsis thraciensis Cheshmedzhieva, 1995, from the Maastrichtian of Bulgaria, differs from the genus Neocoeniopsis in forming a rather fasciculate colony by marginal budding and having abundant synapticulae that occur throughout the corallum (see plate 15, fig. 1 in Cheshmedzhieva, 1995). In Neocoeniopsis the corallite integration is plocoid and synapticulae are sparse, mainly restricted to the vicinity of corallite wall. In addition, the septal apparatus of Neocoeniopsis thraciensis as shown on plate 15, fig. 1. in Cheshmedzhieva (1995) closely corresponds to the brachyphylliid type but clearly differs from the kind developed in the pachyphylliids, to the later of which, also in the opinion of the author Cheshmedzhieva, Neocoeniopsis belongs.
