Formicivora paludicola sp. nov. (Sao Paulo Marsh Antwren) is described from 13 specimens (nine males and four females) collected in the municipalities of Mogi das Cruzes, Salesopolis, and Sao Jose dos Campos, near the city of Sao Paulo, in the east of the state of Sao Paulo, southeastern Brazil. Males of the new species are distinct from those of F. acutirostris (Marsh Antwren), its sister species, by their black underparts and thighs, very dark grayish brown upperparts, and smaller exposed culmen. Females can be distinguished from those of F. acutirostris by the color of the upperparts and flanks, which are also very dark grayish brown, and by the smaller exposed culmen. Mitochondrial DNA sequences also distinguish these two species and the analysis of their vocalizations also showed differences, mainly in the frequency in which certain phrases of the vocal repertoire are used. Sao Paulo Marsh Antwren inhabits marshes where the vegetation is high (ca. 60-250 cm). The species was found in 15 small and isolated areas, at the headwaters of the rivers Tiete and Paraiba do Sul, at altitudes between 600 and 760 m a.s.l. One of these areas was later flooded by the construction of a dam. Most of the marshes where the new species was found are heavily degraded by sand mining, housing developments, fish farming, drainage for cattle raise and agricultural activities, invasion by exotic plants and fire. We propose urgent measures for the protection of this new species.
