Corystidae is a family of crabs, in its own superfamily, Corystoidea. It includes what was once thought to be the oldest Eubrachyuran fossil, Hebertides jurassica, thought to be dating from the Bathonian (Middle Jurassic); the species was subsequently reinterpreted as being Cenozoic in age. Corystidae contains ten extant and five extinct species in eight genera: Corystes Bosc, 1802 Corystites Lőrenthey, in Lőrenthey & Beurlen, 1929 Gomeza Gray, 1831 Gomezinus † Collins, Lee & Noad, 2003 Harenacorystes † Van Bakel, Jagt, Artal & Fraaije, 2009 Hebertides † Guinot, De Angeli & Garassino, 2007 Jonas Hombron & Jacquinot, 1846 Micromithrax † Noetling, 1881 References External links Crabs Extant Miocene first appearances Decapod families Taxa named by George Samouelle
