Races stictopterus and femininus, with geographical distributions interposed between those of nominate and berlepschi, are apparently also phenotypically intermediate between them; their taxonomic status is in need of review. Four subspecies recognized.

Subspecies and Distribution
  • M. l. berlepschi (Hellmayr, 1910) – E Ecuador (extreme E Orellana), NE Peru (Loreto) and extreme W Amazonian Brazil (R Solimões E to Tonantins).
  • M. l. stictopterus Todd, 1927 – C Amazonian Brazil (lower R Branco#R, lower R Negro and nearby R Solimões).
  • M. l. femininus (Hellmayr, 1910) – lower R Madeira, in SC Amazonian Brazil.
  • M. l. lugubris (Cabanis, 1847) – R Amazon, from R Madeira E to Baía do Guajará (CE Amazonas, NC Pará).
