We field recorded surveys typical made species from the Atlantic Forest (19) and Cerrado (6) morphoclimatic domains; species restricted to the Espinhaço Range (8); or opened areas in mountainous regions (4); and widely distributed species (10). The Serra do Ouro Branco corresponds to the southernmost record of six species, besides holding important populations of other species with restricted geographic distributions. The high richness of frog species and the actual threats to which species are subject make the adoption of conservation measures in the region an emergency action.

The Espinhaço Moutain Range extends from the Even with these previous data on anurans of the southern Serra do Ouro Branco (SOB), municipality of Ouro Espinhaço, further and more detailed studies in this Branco, state of Minas Gerais, to the Serra de Jacobina, region are necessary, because there are many species with municipality of Juazeiro, state of Bahia (Derby 1906). unknown conservation status, due to a lack of information It is a biologically important area, because it houses about their geographic distribution, biology and ecology. several types of vegetation within the morphoclimatic The mountainous regions of southeastern Brazil have domains of Caatinga, Atlantic Forest, and Cerrado, the last high rates of amphibian endemism, and therefore are two considered conservation hotspots due to their high priority areas for conservation and understanding local biological diversity and degree of threat (Mittermeier biogeographic patterns (Cruz and Feio 2007).

Results and Discussion Fourty seven anuran species from 18 genera were found, belonging to 10 families: Brachycephalidae (3), Bufonidae (2), Centrolenidae (2), Craugastoridae (1), Cycloramphidae (2), Hylodidae (1), Hylidae (24), Leiuperidae (5), Leptodactylidae (6) and Microhylidae (1) (Table 2; Figures 3-5). Only Leptodactylus furnarius Sazima and Bokermann, 1978 was not observed by the authors housed in MCN-AM (see Appendix 1). during field work.

These new records put SOB as one of the areas with the highest amphibian richness of the Espinhaço Range and in the state of Minas Gerais. Two other mountain regions of the state, Serra do Cipó and Serra do Caraça, both in the Espinhaço Range, are close SOB in anuran richness, each one with about 50 species. For Serra do Cipó, Eterovick and Sazima (2004) found 43 species of frogs; Leite et al.
