Dimensions. c-c (same series)= 2–8 mm, up to 10 mm in peripheral areas; c-c (adjacent series)= 6–14 mm; s/ mm=9–12/5, in areas of intense budding up to 16/5.

Description. Corallum is in the form of a free colony, convex above and elliptical in outline; base flat or slightly concave, sometimes covered by a smooth epitheca; corallites arranged in circumoral rows; generally, no central calice is present; in juvenile forms slightly dominant central corallites may be present; septa thick, straight or wavy, equal in thickness, and porous or subcompact, laterally covered with numerous pennulae and granules that vary in size and shape; 12 to about 24 septa reach corallite centre; axial part of corallites can be free or filled with a trabecular columella; endotheca consists of thin dissepiments; synapticulae very abundant; no wall between the corallites; microstructural features not preserved.

Type locality of species. Cenomanian of the Arabian Gulf (Sokrota Island) .

Distribution. Upper Albian-Cenomanian of the Arabian Gulf (Sokrota Island), Campanian-Lower Maas-
