Eriphioidea is a superfamily of crabs containing the six families Dairoididae Eriphiidae Hypothalassiidae Menippidae Oziidae and Platyxanthidae. They are united by a number of characters including a marked difference in size between the left and right claws where the larger one has a crushing tooth and the smaller one does not and the relative breadth of the male abdomen.
