There are a few localities in the departments of Treinta y Tres, Cerro Largo, and Tacuarembó in Uruguay and disjunctive in southern Brazil (Paraná, Santa Catarina and Rio Grande do Sul), and Corrientes in Argentina. It probably occurs more widely than current records suggest, especially in areas between known sites. It has been recorded from 90-1,000m asl.
Habitat and Ecology
It is exclusively living in open grassy habitats. It occurs in small waterbodies, such as ponds or temporary puddles where it breeds explosively.
It is uncommon but stable in Brazil. It is considered abundant in Argentina and Uruguay.
One major threat is habitat degradation due to agricultural activities and water pollution. Fire is also a potential threat.
It occurs in several protected areas in Brazil. It is not known from protected areas in Argentina or Uruguay.
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 previously with the genus Hyla, but was recently moved to Scinax (Faivovich, et al., 2005). It was removed from the synonymy of Hyla minuta bivittata by Langone (1990).
