Juruena, c. 490 km NW of Cuiabá, Mato Grosso, Brazil.
Has sometimes been placed in monotypic Rhynchothraupis, or suggested to be conspecific with C. speculigera, but new vocal information and knowledge of female plumage indicate a possible link with Sporophila fringilloides (Sporophilinae), although another report mentions vocal similarity to Ramphocelus carbo, in present subfamily. Further research required. Monotypic.
W Mato Grosso (upper R Juruena Basin) and SW Goiás (Emas National Park), in SC Brazil.
