Race striatidorsus doubtfully distinguishable from nominate; also, birds from N Peru (Amazonas S to La Libertad, from where no specimens known until recently) are intermediate in ventral coloration and extent of streaking between nominate and moderatus, and latter exhibits increasing tendencies towards nominate in populations farther N, and significantly smaller body size in extreme S; quantitative analysis, including specimens from intervening localities, may show that all geographical variation is clinal and that no division into races is warranted. Three subspecies tentatively recognized.

Subspecies and Distribution
  • T. h. striatidorsus (Berlepsch & Taczanowski, 1884) – W Andes of W Colombia (Páramo de Frontino#R, S from Cauca) and W Ecuador (S to Chimborazo).
