Ninabamba (2100 m), Apurímac, Peru.
Apparently closest to G. brasilianum, G. tucumanum and G. nana. Recently separated from G. brasilianum on basis of bioacoustical analysis and DNA evidence. Later research suggests that populations currently included in present species constitute two species, one on Pacific slope and the other on Amazonian slope; they differ markedly in morphology and, particularly, vocalizations; name peruanum is applicable to birds of Amazonian slope. Currently treated as monotypic.
