P. L. Sclater, 1858,
Río Napo, Ecuador.
Formerly treated as conspecific with geographically remote D. plumbeus, and inappropriately transferred to Thamnomanes; differs clearly from D. plumbeus in morphology and, especially, vocalizations#R. Race tucuyensis, widely separated geographically from nominate, is fairly distinctive and has been treated as a separate species#R; however, plumage differences appear to be equivocal, and vocal differences (in both loudsongs and calls) to date insufficiently known to justify separation at species level#R; further study required#R, including molecular analyses. Two subspecies recognized.
