Beauvais, 1982, vol. 1, p. 138

Type Species

Ulastrea edwardsi Reuss, 1854: 115, pl. 16, figs. 1-3.; Original Designation Beauvais, 1982: vol. 1, p. 138

Type Specimen: Holotype; unknown; Not Traced; Unknown

Type Locality: Upper Turonian to Campanian of Austria (Gosau Group).

The holotype of the type species is housed at the Oberosterreichisches Landesmuseum Linz, Austria, under 21/1990, Reuss collection.

Classification

Diagnosis

Colonial, massive, plocoid. Gemmation generally extracalicinal. Costosepta compact, nonconfluent, arranged radially and bilaterally, spinose laterally, moniliform marginally. Columella spongy-papillose or formed by twisted segments, absent in some corallites. Synapticulae absent. Auriculae sparse or absent. Perithecal dissepiments sparse. Endothecal dissepiments vesicular, forming a stereozone. Wall parathecal-septoparathecal, thick.

Remarks

Originally, the genus Reussicoenia was placed in the Placocoeniidae. Re-investigation of the type material by Baron-Szabo (2010) revealed, however, that it showed close affinities to the Agatheliidae. Based on the presence of: compact septa that have numerous spiniform granulae laterally and are beaded marginally; granulated peritheca formed by (incomplete) concentric lamellae; ; plocoid polyp integration; septothecal developments that often consist of stunted septa; the genus Reussicoenia is here transferred to the Agatheliidae.
