DIVERSITY AND DISTRIBUTION OF THE MOUSE OPOSSUMS OF THE GENUS THYLAMYS (DIDELPHIMORPHIA, DIDELPHIDAE) IN NORTHEASTERN AND CENTRAL ARGENTINA

Phylogenetic analysis of a fragment of the mitochondrial genome and qualitative and quantitative assessments of morphological variation suggest that, in its current conception, Thylamys pusillus (Desmarest, 1804) is a complex of at least three species. In the taxonomic arrangement proposed in this w...
