Etymology Name comes from the Latin word “reliquiae” meaning “old remains” [details]
Morphology Although molecular data do not closely affiliate this taxon with Actiniaria, the ultrastructure of its nematocysts strongly suggest that it belongs within Actiniaria: basitrichs of Relicanthus daphneae comb. nov. have apical flaps and the distal tubule of microbasic p-mastigophores of R. daphneae comb. nov. does not have spines; these features recall those of Actiniaria.
