Angeli, 2012 [middle Eocene]; Galathea sahariana Garassino et al., 2008 [Cenomanian/Turonian]; Galathea squamifera Leach, 1814 [Messinian–Recent]; Galathea strigifera von Fischer-Benzon, 1866 [Danian]; Galathea valmaranensis De Angeli & Garassino, 2002 [Oligocene]; Galathea weinfurteri Bachmayer, 1950 [late Oligocene–middle Miocene].

Discussion: Baldanza et al. (2013) called Galathea affinis a nomen dubium because the holotype and another specimen were lost and because of the poor quality of the line drawing in Ristori (1886: pl. 2.18). However, the line drawing shows all details of the carapace, including many spines on and around the rostrum; therefore, we do not consider this species a nomen dubium. We consider Galathea antiqua Risso, 1816 a nomen nudum because a holotype, type locality, age, illustration and a detailed description are unknown (see ICZN article 12). Galathea lupiae Robineau-Desvoidy, 1849 , only known from an appendage fragment from the Neocomian (Berriasian– Hauterivian) of France, is not identifiable; therefore, we consider this specimen incertae sedis within Decapoda .
