The Cricetidae remains from Buñol, collected by field parties of the Department of Paleontology (State University of Utrecht, The Netherlands), are described. Three previously known species have been recognized: Megacricetodon minor primitivus (Freudenthal, 1963), Democricetodon aff. hispanicus Freudenthal, 1967 and Fahlbuschia cf. koenigswaldi (Freudenthal, 1963). One new species is described: Eumyarion valencianum. The presence of M. m. primitivus points to an Early Miocene age (collongensis Assemblage-Zone).
