| J. S. Zijlstra et al. 2014 | A cricetid rodent distinguished by the follow- ing combination of characters: molars strongly cuspidate; cusps opposite in upper molars, slightly alternate in lower molars; anteroloph of M1 short or absent; paracone of M1 connected to anterior part of median mure; median mure of M1 connected to protocone; mesoloph present in most upper molars; paracone of M2 connected singly to protocone at middle of protocone; protoflexus of M2 present; posteroloph and hypoflexus present on M3, hyp- oflexus shallow to moderately deep; M3 relatively narrow; mesolophid absent in nearly all lower molars; m1 relatively long; anterolabial cingulum present on m1–3, but relatively weak on m2; anterolophid absent from m2 and m3; lower second molar with two roots; masseteric ridges conspicuous.
