We thank the Natural Sciences Research Laboratory of the Museum of Texas Tech University, Lubbock, Texas, USA for providing tissue samples for the specimens of C. tener. We are very grateful to Ulyses F.J. Pardiñas (CENPAT, Puerto MadrynArgentina), for providing most of the samples from Misiones (Ar-gentina) used in this study. We also thank to Juan Diego Pinotti (IDEA, UNC-CONICET, Córdoba, Argentina) for his assistance to make the map. This work was supported by the Agencia Nacionade Promoción Científica y Tecnológica, Argentina (PICT 2016 #1328), by the Secretaría de Ciencia y Tecnología (SECyT-UNC)Universidad Nacional de Córdoba, Argentina. We acknowledge the contribution of the Graduate School, Texas Tech University (Doctoral Dissertation Completion Fellowship to NPK) and Texas Tech University Proposal Stimulus Program (to JSB).

N2 - The nominal species Calomys tener (Winge, 1887) ranges broadly in open lands of the Caatinga, Cerrado, Pantanal and Mata Atlântica of Brazil, and was recently reported from the Pampas of southern Brazil, and in the Selva Paranaense of eastern Paraguay and northeastern Argentina. This rodent can be infected with the pathogenic Araraquara hantavirus in Brazil. Given that most epidemiological studies have not taken into account updated taxonomic findings of their rodent hosts, in this study, we obtained sequence data of the Cyt-b and COI genes of specimens of C. tener from 22 different geographical localities from throughout the currently known distribution of the species (including individuals from Argentina, Paraguay, Bolivia, and Brazil) to test if it constitutes a single genetic unit or if it presents genetic discontinuities that may represent different evolutionary lineages. Phylogenetic analyses including several species of Calomys recovered several clades with strong support. Regarding C. tener, it is recovered as sister to the node that cluster C. laucha (Fischer, 1814) sensu lato, C. expulsus (Lund, 1841) and species in the C. callosus (Rengger, 1830) species complex. At the intraspecific level there are no genetic gaps among haplotypes of C. tener that could suggest more than one species. The recent captures in the Pampas of southern Brazil and in the Selva Paranaense suggest that the species may be colonizing new geographic areas.
