Discussion: Phyllotini . Doubtfully retained as a genus distinct from Phyllotis by Ellerman (1941), later included in Phyllotis as a formal subgeneric division ( Osgood, 1947; Pearson, 1958) or not ( Hershkovitz, 1962). Thomas (1919) remained firm regarding the generic distinctiveness of Phyllotis and Graomys , and the latter was so reinstated based on karyological data ( Pearson and Patton, 1976) and other traits (see Olds and Anderson, 1989; Reig, 1978). Generic stature uniformly reinforced in broad phylogenetic studies of phyllotine taxa, using either morphological characters ( Braun, 1993; Steppan, 1993, 1995) or molecular data ( Anderson and Yates, 2000). Also see remarks under Andalgalomys , which Steppan (1995) included as a subjective synonym of Graomys .

Williams and Mares (1978) transferred Graomys pearsoni Myers, 1977 , to Andalgalomys , and Massoia (1976) synonymized G. hypogaeus Cabrera, 1934 , with Eligmodontia typus . Pardiñas (1995) identified the synonymy of Bothriomys with Graomys , contra Herskovitz (1962) who placed it under Euneomys ( McKenna and Bell [1997] placed it under both Graomys and Euneomys ), and recommended retention of Graomys as nomen protectum, it being the familiar and long used genus-group name for these phyllotine rodents .
