Axiidean and brachyuran decapods are reported from the middle–late Miocene pre-evaporitic deposits of several localities along the Valmarecchia (Rimini) in the Romagna Apennines (Emilia-Romagna). Goneplax rhomboides (Linnaeus, 1758), already known from the Miocene of Italy, has not been recorded previously in this area, while the record of Chlinocephalus demissifronsRistori, 1886 expands the stratigraphic range of the genus, previously known only from the Pliocene and Pleistocene of Italy. Moreover, some specimens are assigned in open nomenclature to LobocarcinusReuss, 1857, already known from the Miocene of Italy. Finally, some loose chelae are assigned to the families Callianassidae and Eucalliacidae, respectively, without generic and specific assignment. The Valmarecchia decapod assemblage enlarges the knowledge on the composition and distribution of the decapod fauna along the palaeo-Adriatic Gulf before the Messinian Salinity Crisis of the Mediterranean Basin.
