REMARKS

The species is only known from the holotype and a thin section from topotypical material. The species (the type material as well the material illustrated by Baron-Szabo et al. 2006 and Baron-Szabo 2008) does not belong to Siderastrea as proposed by Baron-Szabo et al. (2006) and Baron-Szabo (2008) because of the strongly perforated radial elements. Siderastrea has compact radial elements which almost do not vary in thickness. The present material cannot be clearly assigned to Pseudofavia because it differs from this genus in various features: the radial elements are more strongly perforated than in Pseudofavia ; the septal symmetry is regular hexameral and not irregular; the costae are confluent rather than nonconfluent; the columella is clearly parietal. The position in the genus Pseudofavia is preliminary. There is not sufficient topotypical material to establish a new genus, but there does exist more material similar to? Pseudofavia adkinsi but showing different calicular dimensions and/or septal counts (IGM 8727 and 8728 from the Maastrichtian of Mexico; USNM #454 and #466 from the Maastrichtian of Jamaica). Baron-Szabo (2008) mentioned and illustrated material from the Danian of Puerto Rico (USNM, Berryhill coll., PR-7 series) that may belong to this genus. This would extend the range of the family into the Danian.
