FIGURE 1. a) Map of southern South America indicating the placement of the collection localities of the specimens of Phyllotis studied in this work (see Appendix 1 for a detail); type localities of nominal forms discussed in the text were indicated by red stars. b) Geographical groups recognized in this study; different colors correspond to the mitochondrial lineages documented by Riverón (2011) as follow: light green = bona (P. bonariensis); dark green = central Argentina; orange = northcentral Argentina; blue = west-central Argentina; red = southern Argentina and Chile. For the acronyms, see Materials and Methods section. Specimens from busw correspond to P. bonariensis, while the remaining samples could be referred to the current concept of P. xanthopygus; individuals from coce, menw, mese, meso, mesw, nqne, nqnw and slno are usually included under P. x. vaccarum, while those of chnc, chwe, chce, chse, chsw, chsc, nqso, rnce, rnsc, scne, scwc, and scnw are traditionally assigned to P. x. xanthopygus.
