near Concepción del Uruguay, Entre Ríos, Argentina.
Has been suggested that present species is a white-throated morph of S. ruficollis or a colour morph of S. hypoxantha, but this not supported by recent molecular studies. Belongs in S clade of “capped” (“capuchino”) Sporophila (see S. castaneiventris and S. bouvreuil; also S. hypoxantha); discriminates S. hypoxantha by song despite lack of genetic differentiation#R. Form described as S. zelichi (from Entre Ríos, in NE Argentina), once treated as a Critically Endangered species, now considered to be a hybrid between present species and S. cinnamomea or a white-necked morph of present species, with which it is vocally identical and found in same habitat and at same locations#R, although treated as full species, without comment, in more recent molecular review#R. Monotypic.
NE Argentina (Corrientes and Entre Ríos, possibly also Buenos Aires), extreme SE Brazil (Rio Grande do Sul) and Uruguay (R Uruguay Basin and SE wetlands), possibly also SE Paraguay. Migrates N as far as SC Brazil (N to S Mato Grosso, S Goiás and W Minas Gerais) and E Paraguay.
