Formerly usually treated in Oryzoborus, when often considered conspecific with S. nuttingi, S. crassirostris and S. atrirostris; race occidentalis of S. crassirostris often placed in present species; taxonomy of this group still in flux. With transfer of present species to Sporophila, name magnirostris becomes preoccupied and is replaced by parkesi. Two subspecies recognized.
