This species ranges widely through some southern parts of Brazil, in the following States: Minas Gerais; the southern part of Goiás; southern Bahia; and the northern part of Espírito Santo. It occurs from sea level up to 1,000m asl.
Habitat and Ecology
It is almost entirely aquatic, and is found in lakes, ponds and other waterbodies in Cerrado and Caatinga savannah, and is often found floating at the surface of the water. It breeds in water. It is not known whether or not it adapts well to anthropogenic disturbance.
It is a common species.
Expanding agriculture is impacting its populations, overgrazing by domestic livestock, infrastructure development (for expanding human settlements, and dams), and water pollution from agriculture are all threats.
It occurs in some protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species was placed in the synonymy of Pseudis paradoxa by Gallardo (1961), but was re-validated by Caramaschi and Cruz (1998).
