Subspecies
No subspecies.
Formerly placed in Aimophila, but molecular-genetic studies indicate that such treatment would make that genus polyphyletic. Various studies suggest that this species is part of a group that includes also Stripe-headed Sparrow (Peucaea ruficauda), Bridled Sparrow (Peucaea mystacalis), Cinnamon-tailed Sparrow (Peucaea sumichrasti) and Rufous-winged Sparrow (Peucaea carpalis), this group being sister to a clade containing Cassin's Sparrow (Peucaea cassinii), Bachman's Sparrow (Peucaea aestivalis) and Botteri's Sparrow (Peucaea botterii). Birds of northern Colima have sometimes been separated as subspecies asticta, but doubtfully valid.
