Subspecies
No subspecies.
New molecular data indicate that genus forms a clade with the tanager (Thraupidae) genera Hemispingus and Thlypopsis, and that Compsospiza, which often subsumed within this genus, is sister to that clade. A recent molecular-genetic study suggested that this species is rather distantly related to very similar-looking Ringed Warbling-Finch (Microspingus torquatus). Found to have a basal position in genus in some analyses, and in a clade with Cinnamon Warbling-Finch (Poospiza ornata) and Bolivian Warbling-Finch (Poospiza boliviana) in other analyses. More work is required in order to determine correct placement of this warbling-finch, and if similarity to Ringed Warbling-Finch (Microspingus torquatus) is due to convergence.
