Discussion: Reithrodontini. Sister genus to Neotomys Reithrodon­ based on cladistic evaluation of morphological characters ( Ortiz et al., 2000 b; Pardiñas, 1997; Steppan, 1995; Steppan and Sullivan, 2000). See remarks under Reithrodon on tribal affiliation. Relatively few specimens exist to substantiate the specific taxonomy and distribution of the genus. Revised by Hershkovitz (1962), who acknowledged several nominal species but indicated their probable synonymy under E. chinchilloides , as Mann (1978) later formalized for Chilean populations. Yañez et al. (1987) summarized extant specimen data for Euneomys and similarly concluded that only one species is represented. Others have recognized two or more (e.g., Gyldenstolpe, 1932; Osgood, 1943; Pearson and Christie, 1991; Pine et al., 1979; Reise and Gallardo, 1990). The latter arrangement is more nearly correct but must be documented by rigorous revisions.
