Molecular data indicate strong support for a clade consisting of present species and M. similis as sister-group to one formed by M. granadensis and M. luteiventris. Races require closer scrutiny; birds from E Panama described as race harterti, on basis of smaller size, but inseparable from hellmayri. Four subspecies currently recognized.

Subspecies and Distribution
  • M. c. hellmayri E. J. O. Hartert & Goodson, 1917 – extreme S Costa Rica#R, SW & E Panama (Chiriquí and S Veraguas, E from Canal Zone), tropical N & W Colombia (W of E Andes), W Venezuela (Maracaibo Basin, and W slope of Andes from W Lara S to Táchira) and W Ecuador (S to El Oro and W Loja).
  • M. c. rufipennis Lawrence, 1869 – N Venezuela (N of R Orinoco), E Colombia E of E Andes (Norte de Santander S to W Caquetá and Vaupés) and E Ecuador.
  • M. c. cayanensis (Linnaeus, 1766) – S Venezuela (Amazonas, Bolívar, Delta Amacuro), the Guianas, N & C Brazil (R Negro E to Maranhão and Piauí, S to E Acre, Rondônia, Mato Grosso do Sul, Goiás and W Minas Gerais), SE Peru (Madre de Dios) and N Bolivia (S to Cochabamba and N Santa Cruz); recently recorded, probably this race, in extreme E Paraguay#R.
  • M. c. erythropterus (Lafresnaye, 1853) – SE Brazil (S & E Minas Gerais, Rio de Janeiro).
