A new species of rust fungus, Maravalia parae on Pera. sp. (Euphorbiaceae), from Brazil is proposed. Spermogonia are type 5 and aeciospores and urediniospores are asymetrically obovoid to ellipsoid, with a concave side and 3(-4) equatorial germ pores. Teliospore walls are 2-5 mu m thick at apex around the apical germ pore. This set of characters differentiates M. perae from other species of Maravalia. A revised key to all known Maravalia species, including the newly discribed species, is provided.
