Hexapodidae is a family of crabs the only family in the superfamily Hexapodoidea. It has traditionally been treated as a subfamily of the family Goneplacidae and was originally described as a subfamily of Pinnotheridae. Its members can be distinguished from all other true crabs by the reduction of the thorax such that only seven sternites are exposed and only four pairs of pereiopods are present.
