Resumen:
The open vegetation biomes, within the limits of the Chacoan subregion,occur along a diagonal in eastern South America covering a large range of environmentalconditions. In order to contribute to the knowledge on the biodiversity of these openbiomes, we analysed the phylogenetic relationships of the grasshopper genus Zoniopodato the remaining South American Romaleinae, and examined the biogeographicalpatterns of diversification of the genus. The study is based on morphological andmolecular (COI and H3) evidence, including 12 species of Zoniopoda and 17 species offour tribes of South American Romaleinae. We describe a new species of Zoniopoda,and test its taxonomic placement within the group. Results of our phylogenetic analysesrecovered Zoniopoda as a monophyletic group with high support values. According tothe dispersion?vicariance analysis, the ancestor of Zoniopoda may have been distributedin an area corresponding to the Chacoan and Cerrado provinces. A vicariant event, thatcould be explained by the uplift of the Brazilian Plateau and the subsidence of theChaco, is hypothesized to have occurred splitting the ancestral distribution of Zoniopoda,resulting in the independent evolution of the Tarsata group within the Cerrado and theIheringi group in the Chacoan subregion.
