GARASSINO, Alessandro; PASINI, Giovanni  and  CLEMENTS, Don. A new spider crab (Brachyura, Epialtidae) from the Castle Hayne Limestone Formation (Eocene), North Carolina, USA. Bol. Soc. Geol.

A new spider crab, Eoinachoides bretoni n. sp. (Epialtidae MacLeay, 1838) from the Comfort Member of the Castle Hayne Formation (Eocene) of Onslow County, North Carolina (USA), is herein described, representing the second spider crab recovered from this member. Although the new species does not enlarge the stratigraphical range for the genus which is currently restricted from the Eocene to Miocene, it is the first report in North America, extending the palaeogeographic distribution of Eoinachoides, limited currently in the fossil record of South America. In addition, an updated list of the species of the Castle Hayne Formation is herein provided.

Keywords : Crustacea; Decapoda; Majoidea; Paleogene; Castle Hayne Formation; taxonomy.
