Families

Pilumnoidea is a superfamily of crabs,[1][2] whose members were previously included in the Xanthoidea.[3] The three families are unified by the free articulation of all the segments of the male crab's abdomen and by the form of the gonopods.[2] The earliest fossils assigned to this group are of Eocene age.[4]
