Hypsiboas curupi is restricted to Misiones, northeastern Argentina, between 300 and 700 masl. Its distribution seems to be associated with the basins of the Paraná and Uruguai rivers. In Brazil, it is potentially present in the state of Paraná (Garcia et al., 2007).
Habitat and Ecology
The vegetation where Hypsiboas curupi is found is seasonal forest and Araucaria forest in Atlantic Forest domain. H. curupi call in the vegetation, on the margins or backwaters of shallow streams, and in forested areas. Individuals perch on trees and vegetation surrounding forest streams at variable heights, at distances of 50–100 cm from water. Males are dusk and nocturnal callers, and when in high densities, tend to call in a chorus. Calling activity and tadpoles were observed in the months of December, January, and February. Males call from the vegetation or partially submerged in water. Spawns are laid in clumps of eggs, laid in water, adhered to vegetation or stones. A spawn was found to contain 263 eggs with a dark animal pole; each egg being covered by an individual jelly capsule. Tadpoles have been found in streams of clear water inside the forest. Other anuran species that share the same area include Aplastodiscus perviridis and Crossodactylus schmidti (Garcia et al., 2007). The advertisement call is reported in Garcia et al. (2007).
