Here we follow Calder et al.(2009) and also retain the original name given by Fraser (1947) pending more detailed study. Distribution in SouthAmerica: polyp—Atlantic Ocean, Venezuela, at 11.18ºN 64.28ºW, off Margarita Island(Fraser 1947; Calder et al.2009). Habitat: polyp—from 38 to 40mdepth (Fraser 1947; Calder et al.2009).
