Galatheoidea is a superfamily of decapod crustaceans comprising some squat lobsters and the porcelain crabs. Two other families of squat lobsters, Chirostylidae and Kiwaidae, are not closely related to the members of Galatheoidea, and are now placed in other superfamilies.[1] The fossil record of the group extends back to the Middle Jurassic genus Palaeomunidopsis.[1]

The following genera are included:[1][2][3]

Galatheidae Samouelle, 1819
Munididae Ahyong et al., 2010
Munidopsidae Ortmann, 1898
Porcellanidae Haworth, 1825

Two further fossil taxa may be included in the superfamily,[3] but were not considered in the latest synopsis.[1] The family Retrorsichelidae contains the single species, Retrorsichela laevis from the Campanian, which was tentatively placed in Galatheoidea by its authors.[4] The Eocene genus Ovocarcinus, containing only O. elongatus, was originally placed incertae sedis.[5]
