Despite extensive ornithological research in SE Peru, this distinctive new species had escaped notice until recently#R, suggesting that it may be limited to larger forest blocks dominated by bamboo (Guadua), a poorly surveyed habitat.

Distribution:

SW Amazonia in S Peru (S Ucayali, Cuzco and Madre de Dios) and adjacent W Brazil (Acre) and NW Bolivia (Pando).
