This species occurs in Uruguay, southeastern Brazil, southeastern Paraguay and central and northern Argentina (Gardner 2007). The populations from the Atlantic Forest assigned traditionally to M. sorex, are now considered as conspecific with M. dimidiata (Vilela et al. 2010, Solari 2010).

This species is found in pastures, wetlands, pampas grasslands, and riparian areas next to waterways. Founded also in Atlantic coast rainforest (Eisenberg and Redford 1999, Emmons and Feer 1997).

Solari, S. & Chiozza, F.
This species is listed as Least Concern in because of its wide distribution, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at the rate required to qualify for listing in a threatened category. This species is in decline and further investigations into rates of decline and adaptability to disturbed habitat could indicate that this species is or will be Near Threatened, however, inference from current knowledge suggests Least Concern is more appropriate at this time.
- 2008Least Concern(IUCN 2008)
- 1996Lower Risk/near threatened
This species can be common in the appropriate habitats (see Pine et al. 1985). Remaining populations of this species have been reduced to isolated fragments of their former range. In southeastern Brazil, northeastern Argentina and southern Paraguay, the population may be larger than thought as surveys have been inadequate.
No major threats occur to the species, although numerous populations are threatened by habitat conversion to agriculture or urbanized areas.
M. dimidiata occurs in a number of protected areas in Brazil.
