Diagnosis
ReferenceDiagnosis
R. A. Martin and R. J. Zakrzewski 2019Archaic species with terraced mastica- tion surface, derived species with planed surface; consistent mesolophulid on m1 in archaic species, absent in Nelsonia; mesolophule on M1 usually present (absent in Protorepomys mckayensis nov. species, Nelsonia); taxa with (Galushamys) or without (Protorepomys nov. genus, Repomys, Miotomodon, Nelsonia) enamel atolls developed on M1 from isolation of the enamel borders of paraflexus and metaflexus; M1 with three roots; m3 simple shield shape, with shallow or no protoflexid in most taxa (Repomys, Nelsonia); M3 usually reduced to single dentine field without flexi, occasionally with vestigial paraflexus (Repomys, Nelsonia). The primary differences between the Neotomina and Galushamyina are the persistent mesolophulid on m1 in ancestral galushamyinans and reduced, simplified M3−m3 morphology in derived taxa of the Galushamyina.
