Resumo

The karyotypes of Phyllomedusa camba De La Riva, 1999 and P. rhodei Mertens, 1926 are presented and the chromosome pairs with Ag-NORs are identified. Both karyotypes have 2n=26 chromosomes with similar morphology, an exception being the presence of three acrocentric pairs in P. camba. In this species the Ag-NORs are found in the proximal region of pairs 1 and 5 whilst in P. rhodei an extensive inter-individual variation was observed in the number and position of the Ag-NORs (1p, 3q, 5p, 8p, 11q, and 12q). Based on comparative cytogenetic data of P. camba and P. rhodei, we discuss the phenetic groups proposed for Phyllomedusa genus. (AU)
