First record of Dynomene (Brachyura, Dromioidea) from the Eocene of the Iberian Peninsula and remarks on the generic placement of Eoacantholobulus oscensis (Brachyura, Xanthoidea)

Abstract

A new species of Dynomene from the Priabonian (Upper Eocene) of the central Pyrenees in Aragón (Spain) is described as the first record of the genus from the Iberian Peninsula. The new species reveals close similarities to other dromioid species described from the Priabonian of Hungary. The panopeid Eoacantholobulus oscensis Ossó & Domínguez, 2017, from the same locality, is reviewed and transferred to the genus Sculptoplax, after comparisons with specimens of Sculptoplax rigida Müller & Collins, 1991 from the Priabonian of Italy. The present note again provides evi- dence of the close relationship between the Late Eocene decapod crustacean faunas of the western-most Tethys and the Pyrenean basins.
