Sete Lagoas, Minas Gerais, Brazil.
Forms a clade with F. melanogaster. Recent study involving morphometric, plumage and vocal analyses#R indicates that present species is polymorphic, varying geographically as N–S cline but showing both individual and inter-populational variation; race littoralis previously treated as a separate species, but both it and interposita lack diagnostic characters or any significant vocal differences from serrana; however, statistical differences between populations could be considered an indication of distinct evolutionary trajectories. Three subspecies recognized.
