Subspecies
Genus sometimes subsumed in Sporophila. Molecular evidence suggests that genus as currently constituted may not be monophyletic, and some of its members may have closest relatives in Sporophila. More data necessary in order to resolve a basal polytomy in the phylogeny. Formerly considered conspecific with Nicaraguan Seed-Finch (Sporophila nuttingi), Great-billed Seed-Finch (Sporophila maximiliani) and Black-billed Seed-Finch (Sporophila atrirostris). Subspecies occidentalis often placed in Great-billed Seed-Finch (Sporophila maximiliani). The taxonomy of this group still in flux.
The following 2 subspecies are recognised:
occidentalis Sclater, PL, 1860 - Pacific slope of Colombia south to south-western Ecuador.
crassirostris (Gmelin, 1789) - Venezuela, the Guianas, eastern Colombia south to north-eastern Peru, and northern and western Brazil (north-western Amazonas, north-eastern Roraima, Amapá and northern Pará). Also Trinidad (at least formerly).
