The dispersal between Amazonia and Atlantic Forest during the Early Neogene revealed by the biogeography of the treefrog tribe Sphaenorhynchini (Anura, Hylidae).

The Amazonia and the Atlantic Forest, separated by the diagonal of open formations, are two ecoregions that comprise the most diverse tropical forests in the world. The Sphaenorhynchini tribe is among the few tribes of anurans that occur in both rainforests, and their historical biogeographic have never been proposed. In this study, we infer a dated phylogeny for the species of the Sphaenorhynchini and we reconstructed the biogeographic history describing the diversification chronology, and possible patterns of dispersion and vicariance, providing information about how orogeny, forest dynamics and allopatric speciation affected their evolution in South America.

Release call of Bokermannohyla ibitipoca Caramaschi amp; Feio, 1990 (Anura, Hylidae).

Bokermannohyla ibitipoca is a small-sized hylid frog (males reaching up to 43 mm in snout-vent length) of the B. circumdata group (Faivovich et al. 2005).

A new species of spotted leaf frog, genus (Amphibia, Phyllomedusidae) from Southeast Brazil.

Based on concordant differences in male advertisement call, tadpole morphology, and absence of haplotype sharing in the barcoding 16S mitochondrial DNA, we describe here a new species of spotted leaf frog of the genus from Atlantic Forest, State of Rio de Janeiro, Southeast Brazil. The new species is most similar to (type locality) and (type locality). It differs from these species by the size of the calcar, moderate-sized body (snout-vent length 30.
