Classification
Remarks
Based on the species Aplosmilia crucifera Felix, 1903, Beauvais (1982, vol. 2, p. 119) created the genus Elasmogyra. According to him, Felix’ material was characterized by fungiid (-funginellid) skeletal structures instead of rhipidogyrid features as were believed by Felix (1903) to be present (they are characteristic of the genus Aplosmilia). However, re-study of the type (Baron-Szabo, 2014, p. 47, pl. 49, figs. 1-6) revealed that in forming phaceloid-subflabellate clumps by intracalicular budding; having septa that are thick near the wall (partly due to merging of adjacent septa) and have rounded to crispate ornamentations laterally; trabecular columellar structures that appear as irregular lamellar segments; a (septothecal-) synapticulothecal wall with occasional pores; and septa that are normally arranged or irregularly follow the Pourtalès plan, the genus Elasmogyra closely corresponds to the genus Rhabdopsammia. Therefore, their synonymy is suggested.
