The Atlantic Rainforest is the second largest tropical rainforest, after the Amazonian Hyalea. During recent decades, however, this vast region has been deforested and is nowadays reduced to 5% of its original distribution (Por 1992).
Although every species must have a distributional limit somewhere, 50 kms strikes me as a trivial distance within the hyalea when our new records offer distributional extensions of as much as 800--1000 kms, especially for hylids, re-inforcing the criticism of Heyer et al.
Once again, the few data I have are for certain species from as far away as 300 kilometers (not exactly close, even for the hyalea).
