A prodigal coral genus returns: Undaria is again Agaricia pending further taxonomic research
Budd et al. (1994) classified species of bifacial Agaricia (agaricities, tenuifolia, humilis) as species of Undaria, and this genus name was adopted by AGRRA in 2013. We have since learned that Undaria is an invalid genus name according to the rules of the International Commission on Zoological Nomenclature (G. van Moorsel, pers. comm.). Pending the results of what we hope will be further molecular and morphological research, Agaricia is replacing Undaria in the AGRRA training and database.
