Family Nidaliidae  

While most nidaliids form branching colonies, species of Nidallia have capitate colonies with a stiff or firm texture and prominent calyces, bearing retractable polyps, in a terminal cluster. Refer to Verseveldt and Bayer (1988) for some revisions within this family.

The family is represented by only one species in the SAB, Nidalia occidentalis Gray, 1835   .
