Family Monorhaphididae Ijima, 1927
Monorhaphididae Ijima (Hexactinellida: Amphidiscophora) is revised to contain only a single genus and single authentic species, Monorhaphis chuni. This family is well differentiated from other Amphidiscophora by the predominance of triactines (tauactines) amongst choanosomal megascleres.
