Diagnosis
ReferenceDiagnosis
R. Daams and H. de Bruijn 1995Miodyromys differs from Peridyromys by the morphology of the upper molars in which the trigone has a U-shape, marked by the protoloph and metaloph joining separately the lingual border. Miodyromys differs from Pseudodryomys de Bruijn, 1966 a by its more numerous ridges, by the metaloph and protoloph joining the endoloph separately, whereas in Pseudodryomys these two ridges meet before reaching the lingual border. (translated from French, Baudelot, 1972)

Medium-sized Gliridae with concave occlusal surface. M1-2 with 6 main ridges. The anterior centroloph is longer than the posterior one. The anterior centroloph may fuse with the posterior one, or one or both of the centrolophs may fuse with extra ridge(s). But none of the centrolophs fuse with the middle part of the metaloph. Extra ridges are only present in thc trigone, and they vary from zero to three. There is always one accessory ridge between the main ridges. The anteroloph and posteroloph are isolated at the labial border. Protoloph and anterior centroloph are labially either connected or separated. Protoloph generally connected to the lingual end of the posteroloph. M1.3 two- or three-rooted, with 5 main ridges, and one to four extra ridges. The accessory ridge between mesolophid and posterolophid is stronger and longer than the other accessory ones. (Translated from German, 1979)
