Study of karyotypes of almost all species of Phyllotis (sensu stricto) and of related genera indicates that Chinchillula, Andinomys, Neotomys, Eligmodontia, and Reithrodon are monotypic genera related to Phyllotis. Graomys (griseoflavus and domorum) and Auliscomys (pictus, sublimis, and holiviensis) are given generic rank. Within the genus Phyllotis, species rank is recognized for haggardi, gerbillus, amicus, darwini, caprinus, magister, wolffsohni, definitus, andium, and osilae. Chromosomal evolution within Phyllotis seems to have progressed from 2n = 70, represented now only by osilae, to 2n = 38, represented by darwini and its close relatives.
