Remarks. Sakai (2005) justified Pseudogourretiinae, a new subfamily later elevated to family rank (Sakai 2011), on the presence of pleurobranchs in the type species of a new genus and species, Pseudogourretia portsudanensis . Pleurobranchs are present in Micheleidae, some Axiidae and some Upogebiidae (Poore, 1994) . Our study of the holotype of Pseudogourretia portsudanensis detected no pleurobranchs (see below). Pseudogourretiidae is therefore synonymised with Gourretiidae .
