A new family, Xenograpsidae, is established to include an unusual genus of grapsoid crabs, Xenograpsus Takeda & Kurata, 1977, associated with shallow hydrothermal vents in the western Pacific Ocean. While Xenograpsus is related to other grapsoid crabs such as the Grapsidae, Varunidae, Sesarmidae, Gecarcinidae, and Plagusiidae, evidence from adult and larval morphology and DNA analyses show that the separation between lineages is very deep, and that it should be regarded as belonging to a distinct family. Key morphological differences relate to the structure of the sternum, orbit, basal antennal segment, shape of third maxillipeds, and gonopore position. The relationships amongst the grapsoid families, as currently conceived, are also briefly discussed.
