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), Large-billed Seed-Finch (Sporophila crassirostris)and Black-billed Seed-Finch (Sporophila atrirostris). Subspecies occidentalis of Large-billed Seed-Finch (Sporophila crassirostris)often placed in present species. The taxonomy of this group still in flux. If present species is placed in genus Sporophila, name magnirostris becomes preoccupied, and must be replaced by parkesi.
The following 3 subspecies are recognised:
magnirostris Cabanis, 1851 - Eastern Venezuela (south-eastern Sucre south to Delta Amacuro, and northern Bolívar along southern bank of R Orinoco), western Guyana and eastern French Guiana to northern Brazil (Amapá and northern Pará).
maximiliani Cabanis, 1851 - Central and eastern Brazil (northern Goiás, central Piauí and Bahia south to central Mato Grosso and northern Sío Paulo).
parkesi Olson, 1981 - Eastern Venezuela (northern Bolívar, south-eastern Sucre, and Delta Amacuro), Trinidad, Guyana, and French Guiana; populations in eastern Brazil (Amapa and northern Pará) probably also this subspecies.
