This species was at one time considered conspecific with S. minuta, but molecular data and vocal details suggest that the two are not very closely related. Belongs in S clade of “capped” (“capuchino”) Sporophila (see S. castaneiventris and S. bouvreuil); recent detailed molecular study involving this species, S. ruficollis, S. pileata, S. palustris and S. melanogaster found that they cannot be distinguished reliably genetically although they have rapidly evolved distinct plumages and songs#R, with field study demonstrating how present species discriminates S. palustris by song#R. Monotypic.

Distribution:

N, W & E Bolivia (La Paz, E Beni and Santa Cruz), Paraguay, Brazil S of Amazon Basin (S Mato Grosso, Goiás and W Minas Gerais S to N Rio Grande do Sul), NW & NE Argentina (Salta S to N Tucumán and N Córdoba; Formosa and Misiones S to Santa Fe, Corrientes and Entre Ríos), and marginally W Uruguay; S populations migrate N.
