Comparison Superficially resembles genus Margarastraea Volz (1896), e.g. M. klipsteini (Frech in Volz 1896:55,pl.5,fig.7) and M. deningeri Wilckens (1937:179,pl.7,fig.1), with low-lying meandroid corallites. Differs from these corals in having septa made of thick trabeculae, showing teeth-like trabecular tips on the distal septal margin. Within genus Margarastraea Frech, septa have a midseptal zone of small trabeculae, never forming thick distal ornamentation. [details]
Description Well described, discussed and illustrated in Caruthers and Stanley, 2008. [details]
Diagnosis Colonial, meandroid to pseudomeandroid; no ridges, wall or epitheca; corallite large; intercorallite spacing wide. Calices interconnected through abundant septa linkages.Septa ornamented with trabecular tips along distal margin. [details]
Remark The species, under the name of Margarastraea pulchra Montanaro-Gallitelli, Russo and Ferrari, 1975, was described by Stanley 1994 from Norian Pucará group, central Peru. [details]
