Corystidae is a family of crabs, in its own superfamily, Corystoidea. It includes what was once thought to be the oldest Eubrachyuranfossil, Hebertides jurassica, thought to be dating from the Bathonian (Middle Jurassic);[1] the species was subsequently reinterpreted as being Cenozoic in age.[2] Corystidae contains ten extant and five extinct species in eight genera:[3]
