Loja, 7000 feet [c. 2130 m], Ecuador.
Present species sometimes treated as conspecific with S. aurantiirostris, but differs fairly strongly in plumage and very strongly in voice—song is a single emphasized polyphonic whistle preceded by a short introductory note vs a song phrase consisting of 3–8 (score 3) monophonic (score 3) notes#R—and now proves to be only distantly related#R. Purported close alliance with S. maxillosus (below; mentioned in HBW) also unsupported by latest molecular evidence#R. Monotypic.
S Ecuador (El Oro and Loja) and NW Peru (Piura, extreme E Lambayeque and Cajamarca).
