Abstract A highly diversified fauna of hermit crabs associated with reef environments from the Serraduy Formation (lower Eocene) in the southern Pyrenees (Huesca, Spain) is described. Other European Eocene outcrops have yielded paguroids associated with a single environment; however, the studied association represents one of the highest paguroid diversities in a single Eocene outcrop worldwide. The new material increases the diversity of known fossil paguroids, including eight species from which six are new:Clibanarius isabenaensisn. sp.,Parapetrochirus serratusn. sp.,Dardanus balaitusn. sp., ?Petrochirussp.,Eocalcinus veterisn. sp., ?Pagurussp.,Paguristes perlatusn. sp., andAnisopagurus primigeniusn. sp. We erected a new combination forPaguristes sossanensisDe Angeli and Caporiondo, 2009 andPaguristes cecconiDe Angeli and Caporiondo, 2017 and transfer them to the genusClibanarius. This association contains the oldest record of the generaEocalcinusandAnisopagurus. Our data demonstrate that paguroids were diverse by the early Eocene in coral-reef environments and fill an important gap between the poorly known Paleocene assemblages and the more diverse mid- to late Eocene ones.UUID:http://zoobank.org/091f7a79-946c-4cd9-bdad-f727695e8503
