Geographical distribution of the sequences and topology of Phyllomedusa produced by Bayesian analysis: (A) Topographic map of South America: squares represent the P. azurea sequences obtained from GenBank, stars represent karyotypes described by Morand and Hernand (1997); Paraguay (green) is the type locality of P. azurea and green shaded region represent the distribution of haplotypes in the same clade; asterisks represent P. hypochondrialis sequences from GenBank; Suriname (red) is the type locality of P. hypochondrialis, the red shaded region represents the distribution of P. hypochondrialis haplotypes in the same clade. Note the distribution of NOR positions in the red clade in the populations samples. (B) consensus Bayesian Inference (BI) of the 2928-bp concatenated sequence of mitochondrial (12S and 16S) and nuclear (Rag-1) genes in Phyllomedusa based on the GTR+R+I model. Bayesian posterior probabilities values are shown at each node. Nodes with support of 1.0 are marked with asterisks.
