| Range Description: | The species has a disjunct range in South America. The species is found from north-central Argentina to Uruguay, Paraguay, part of Bolivia, and the southern region of Brazil, from Rio de Janeiro through to the Beni River in Bolivia. The northern range is from eastern Colombia, Venezuela through western Guyana (Gardner 2007). The species has been recorded from southeastern Peru on the border of Bolivia (Romo et al. 2002). The species is suspected to be found continuously down the Orinoco River in Venezuela, although there are no records (D. Lew and P. Soriano pers. comm.). |

| Habitat and Ecology: | Very little information is available on this species. Occurs in wet grasslands It is reported to be nocturnal, preying on small vertebrates, fish, and insects. One stomach contained remnants of mollusk shells and sand, and this species has been caught in traps baited with mice. In captivity Lutreolina will eat insects and fruit and kills birds and mammals up to the size of Microcavia. This mesic-adapted animal is found along areas of permanent water. It is somewhat weasel-like in shape and apparently in habits as well. It can swim, and it climbs well. It occurs to at least 2,000 m elevation in the Andes of southern Bolivia (Emmons and Feer 1997). |
| Systems: | Terrestrial; Freshwater |
| Major Threat(s): | No major threats although in the southern part of its range, drainage of wetlands for agriculture may be affecting the species. |
| Conservation Actions: | This species occurs in a number of protected areas. |
