This species is known from the type locality, Campo Grande da Serra, and nearby Nova Manchester in São Paulo, in the state of São Paulo, Brazil. The type locality is between 600 and 800m asl.
Habitat and Ecology
Specimens were found on shrubs by the side of a brook at the type locality. There is no information on breeding habits, but reproduction might take place in streams.
This species is only known from a few specimens, and recent surveys in the area have not recorded it.
Habitat loss due to infrastructure development has destroyed the species' habitat at the type locality. Chytridiomycosis also cannot be ruled out as a threat.
This species does not occur within a protected area, and protection of any remaining habitat for the species is urgently needed. Further survey work is required to determine the biology and population status of this species, and whether or not it still survives at, or outside the vicinity of, the type locality.
This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Hypsiboas (Faivovich et al. 2005).
