Bangsia melanochlamys occurs in two disjunct areas of western Colombia. The first is on the north and west slopes of the Central Andes in Antioquia, where it had not been recorded since 1948, until rediscovered in 1999 to the west of the Nechí river. This recent study found it to be the most common species in the Reserva la Serrana⁸. The second area is on the Pacific slopes of the West Andes in Chocó, Risaralda and Valle del Cauca, around Cerro Tatamá and Mistrató, including Alto de Pisones, where it is also common^1,4,5,8.
