Xanthoidea is a superfamily of crabs comprising the three families Xanthidae Panopeidae and Pseudorhombilidae. Formerly a number of other families were included in Xanthoidea but many of these have since been removed to other superfamilies. These include Carpilioidea Eriphioidea Hexapodoidea Pilumnoidea and Trapezioidea. Even in this reduced state Xanthoidea remains one of the most species-rich superfamilies of crabs.
