Subspecies
No subspecies.
Chestnut-throated Seedeater (Sporophila telasco) and Tumaco Seedeater (Sporophila insulata) (Sibley and Monroe 1990, 1993) have been lumped into Sporophila telasco following Stiles (2004) who considered insulata a subspecies or colour morph of Chestnut-throated Seedeater (Sporophila telasco).
Molecular evidence suggests that genus is closely related to Oryzoborus, which should perhaps be subsumed within it. Further, that both genera should be placed in the tanager family (Thraupidae). Affiliations uncertain. Plumage resembles that of female Parrot-billed Seedeater (Sporophila peruviana), and conceivable that the two are closely related. A molecular-genetic study is required.
