Subspecies
Placed in genus Phacellodomus by some authors. Subspecies vary markedly in size. This, and the anomalous pattern of their distribution and unusual combination of habitats, could suggest that the three subspecies are separate species. Further research needed.
The following 3 subspecies are recognised:
dimorpha Bond & Meyer de Schauensee, 1941 - Eastern Ecuador (Napo) and south-eastern Peru (Pasco, Junín, Cuzco, Madre de Díos, Puno).
obidensis Todd, 1925 - Central Brazil (lower R Madeira, and central R Amazon in eastern Amazonas and Pará).
