Diagnosis
ReferenceDiagnosis
M. Freudenthal 1970Molars moderately hypsodont, with continuous longitudinal lophs; smaller than those of R. europaeus, about the size of R schaubi; the most characteristic feature is the relative length of M3, which, compared to the lengths of M1 and M2, is longer than it is in any of the known species of Ruscinomys or Cricetodon, sensu stricto.
