Thought to be closely related to M. williami, M. baroni, M. odomae, M. theresiae and M. eupogon. Race malagae formerly considered a distinct species, but, in context of typical infraspecific variation within present genus, morphological differences justify only subspecific separation; research into vocalizations and other behaviour, however, desirable. Two subspecies recognized.

Subspecies and Distribution
  • M. a. aeneocauda (Gould, 1846) – Brassy Metaltail – E Andean slopes from SE Peru (Cordillera Vilcabamba) to NW Bolivia (Yungas of La Paz).
  • M. a. malagae Berlepsch, 1897 – Reddish Metaltail – Incachaca (in Yungas of Cochabamba), in C Bolivia.
