Up to HBW, this species was considered conspecific with A. flavinucha, but the two differ markedly in voice and plumage. Green-backed races virididorsalis, victorini and baezae also have more greenish-blue vs powder-blue fringes to wings and tail, but latter character also shared by black-backed venezuelanus and somptuosus at N and S range extremities; no vocal differences known that align with these plumage variations. Race alamoris extremely similar to nominate and possibly better synonymized with it; provisionally retained pending review of all races. Eight subspecies currently recognized.

Subspecies and Distribution
  • A. s. venezuelanus (Hellmayr, 1913) – N Venezuela (coastal cordillera from Yaracuy E to Miranda).
  • A. s. virididorsalis (Phelps, Sr & Phelps, Jr, 1949) – Aragua (Cerro Golfo Triste), in N Venezuela.
  • A. s. antioquiae (Berlepsch, 1912) – N end of W Andes, both slopes of C Andes (in Antioquia) and E slope (in Tolima), in N Colombia.
  • A. s. victorini (Lafresnaye, 1842) – Andes of W Venezuela (S Táchira) and W slope of E Andes of Colombia (from Santander S to head of Magdalena Valley, in Huila).
  • A. s. cyanopterus (Cabanis, 1866) – Andes of S Colombia (W slope of C range S from Quindío) and W Ecuador (S to Chimborazo and NE Azuay).
  • A. s. alamoris (Chapman, 1925) – S Ecuador (W slope in S Azuay, El Oro and W Loja).
  • A. s. baezae (Chapman, 1925) – E slope of Andes in SW Colombia (Nariño) and Ecuador (S to Morona-Santiago).
  • A. s. somptuosus (Lesson, 1831) – E slope of Andes in extreme S Ecuador (Zamora-Chinchipe) S to SC Peru (Urubamba Valley, Cuzco)#R.
