Perhaps only a race#R and evidently weakly differentiated in voice from F. acutirostris, but detailed molecular analyses#R indicate that paludicola and acutirostris represent distinct clades and reciprocally monophyletic groups. Further, (from published data#R) differs in its black vs dark grey underparts in male (2); dark greyish-brown vs dark brown upperparts in male (1); shorter bill (effect size for female –5.75, score 3); wider bill (effect size for female 0.83, score 1). Monotypic.
SE Brazil in E São Paulo (headwaters of the R Tietê and R Paraíba do Sul Basins)#R.
