The type locality of this species is Sierra de Ánimas, Maldonado Province, Uruguay, at an elevation of 350-500m asl. It occurs in an area of less than 10km².
Habitat and Ecology
It occurs in grasslands and rocky outcrops, and reproduces in permanent small streams. Its tolerance to habitat disturbance is unknown.
It is common at its only known locality, and has not undergone any change in population size in 10 years of monitoring from 1990 to 2000.
Although there are currently no major threats to the species, habitat loss and degradation due to wood plantations and touristic activities might result in declines in the future.
It does not occur in any protected areas. This species requires continued close population monitoring particularly since it is known only from a single location.
