Abstract: Despite their ecological importance, anuran diversity and distribution remain poorly studied in transitionalregions of western Brazil. We surveyed the anuran assemblage in the Municipality of Corguinho, Mato Grosso doSul, a transitional zone between the Central Brazilian Plateau (Cerrado) and the Pantanal floodplain. We recorded 32species in five families: Bufonidae (3), Dendrobatidae (1), Hylidae (11), Leptodactylidae (14), and Microhylidae (3).Our results highlight the role of this underexplored ecotone in supporting a diverse anuran fauna characteristic of bothbiomes. In addition to updating the regional species list, we report a substantial range extension for Pseudopaludicolaameghini, expanding its known distribution approximately 490 km to the south. These new data reinforce the ecologicalvalue of transitional zones and underscore the need for continued biodiversity assessments in such threatened areas.
