Subspecies
No subspecies.
Molecular data indicate that genus is more closely related to the tanagers (Thraupidae) than to members of present family. Furthermore, this species was found to be embedded within genus Saltator, as sister-species of Black-throated Saltator (Saltator atricollis), with the Saltator clade sister to all other Thraupidae. Further research required.
