Etyiidae is a prehistoric family of dromiacean crabs only known from Cretaceous and a few Paleocene fossils.
Genera
In their A classification of living and fossil genera of decapod crustaceans (2009), De Grave and colleagues include seven genera in Etyiidae: Caloxanthus A. Milne-Edwards, 1864 Etyus Mantell, 1822 Etyxanthosia Fraaije, Van Bakel, Jagt & Artal, 2008 Feldmannia Guinot & Tavares, 2001 Guinotosia Beschin, Busulini, De Angeli & Tessier, 2007 Sharnia Collins & Saward, 2006 Xanthosia Bell, 1863
More recently, several the more genera have been described and the family split into two. The World Register of Marine Species recognises eight genera in Etyidae and four in Feldmanniidae as follows:
Etyidae Guinot & Tavares, 2001
Etyus Etyxanthosia Guinotosia Karyosia Rolerithosia Secretanella Sharnia Steorrosia
Feldmanniidae Schweitzer, Feldmann, Franţescu & Klompmaker, 2012 Bretonia Caloxanthus Cantabroxanthus Feldmannia
