Morphological, vocal and molecular studies indicate that, with exception of F. iheringi, all species placed in current genus form a well-defined group. Present species considered to belong to a clade along with F. serrana and F. melanogaster. Forms a superspecies with former and previously considered conspecific, but accorded species status on basis of differences in morphology and ecology; also, has been treated as race of latter. Monotypic.
