From the IUCN Red List Species Account:


Range Description

This species is known from Santa Catarina and Rio Grande do Sul, Brazil, at elevations of 0-1,200m asl.

Habitat and Ecology

It occurs in forests, but also adapts well to human-disturbed habitats. It breeds in small temporary waterbodies such as puddles, gutters, or ditches. The spawn is deposited in small foam nests under roots, leaves or branches at the margins of waterbodies.


It is abundant and stable in suitable habitats.

Population Trend


Major Threats

It is probably locally impacted by severe habitat loss, for example from commercial cattle ranching, expanding wood plantations, clear felling, and expanding human settlements. However, it is generally adaptable and not significantly threatened.

Conservation Actions

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 broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
