Until recently considered conspecific with D. caudata (along with D. klagesi and D. hellmayri), but acoustic and genetic data#R indicate significant differences. Differs from D. caudata in its lack of black mid-crown to hindcrown in male (2); and loudsong with many fewer (3) and level-pitched vs rising (2) introductory notes#R; and from D. klagesi and D. hellmayri in characters given under those species. Same study#R suggests present species might be divisible into four races, with nominate (W & C Colombia), occidentalis (S Colombia to N Peru), peruviana (C Peru) and boliviana (S Peru and W Bolivia), but concludes that further research is required; prior to this study, all four were synonymized with what was nomínate D. caudata caudata (now monotypic D. caudata). Monotypic.

Distribution:

W & C Andes of Colombia, Ecuador (both slopes), Peru (E slope) and NW Bolivia (E slope in La Paz).
