Green tree frogs of the genus Aplastodiscus occur in the Atlantic Forest and Cerrado biomes of SouthAmerica. The genus comprises 15 medium-sized species placed in three species groups diagnosed mainlyby cloacal morphology. A phylogenetic analysis was conducted to: (1) test the monophyly of these speciesgroups; (2) explore the phylogenetic relationships among putative species; and (3) investigate speciesboundaries. The dataset included eight mitochondrial and nuclear gene fragments for up to 6642 bpper specimen. The results strongly support the monophyly of Aplastodiscus and of the A. albofrenatus andA. perviridis groups. Aplastodiscus sibilatus is the sister taxon of all other species of Aplastodiscus, makingthe A. albosignatus Group non-monophyletic as currently defined. At least six unnamed speciesare recognized for Aplastodiscus, increasing the diversity of the genus by 40%. A fourth species group, theA. sibilatus Group is recognized. Aplastodiscus musicus is transferred from the A. albofrenatus Group to theA. albosignatus Group, and A. callipygius is considered a junior synonym of A. albosignatus. Charactersrelated to external cloacal morphology reveal an interesting evolutionary pattern of parallelisms andreversions, suggesting an undocumented level of complexity. We analyze, in light of our phylogeneticresults, the evolution of reproductive biology and chromosome morphology in Aplastodiscus.
