Acryptolaria operculata Stepanjants, 1979

Synonyms in the area: Acryptolaria patagonica El Beshbeeshy, 1991 nomen nudum; Acryptolaria patagonica El Beshbeeshy, 2011 [polyp].

Remarks: the name Acryptolaria patagonica El Beshbeeshy, 1991 is a nomen nudum because it was first proposed in an unpublished dissertation (El Beshbeeshy 1991, 2011). Recently, this name was made available by El Beshbeeshy (2011) (see article 50.1 of ICZN 1999). However, A. patagonica have been synonymyzed to Acryptolaria operculata Stepanjants, 1979 by Peña Cantero et al. (2007), and therefore, this is the valid name of the species.
