This species is known from several localities in Misiones Province, Argentina, and in the states of Paraná, Santa Catarina, and Rio Grande do Sul, Brazil, at elevations of 150-1,200m asl.
Habitat and Ecology
This species can be found in forest patches along margins of small streams. It reproduces in flowing streams. It evidently tolerates some level of disturbance because it is found along streams in pastures and young second growth.
It is uncommonly seen because of its habits, but regularly encountered when sampling with pitfall traps in appropriate habitat.
Habitat loss due to selective logging and clear-cutting of old growth forests, cattle ranching, and forest plantations are all threats to this species. Water pollution caused by agricultural practices (cattle) and industrial pollution (organic wastes) is another threat.
It occurs in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
