ABSTRACT
This study presents a taxonomic treatment of the phytopathogenic fungus Maravalia bolivarensis (Pucciniales) causing rust in plants of Manilkara sp. (Sapotaceae), in the Amapá National Forest, Amapá State, Brazil. Previously known only from Venezuela, this is the first record of M. bolivarensis for Brazil, and its original distribution is extended to the Amazon Biome. Morphological descriptions, illustrations of the microstructures, examined material, geographic distribution and taxonomic comments are provided for this species. Additionally, Maravalia sapotae (Mains) Y. Ono was also recorded in the Amapá National Forest and is being referred here for the first time to the state of Amapá. Finally, an identification key including species of the teleomorph genera Achrotelium, Catenulopsora and Maravalia that occur on plants of Sapotaceae in Brazil is presented.
