Myrmeciza hemimelaena castanea
J. T. Zimmer, 1932,
Río Negro, 2600 feet [c. 790 m], San Martín, Peru.
Until recently considered a race of S. hemimelaena, but shows minor morphological and more notable vocal differences, with some syntopy recorded#R; recent phylogeographical analyses#R found the two to be sisters. Racial identity of N populations in S Colombia (Putumayo) and at lower elevations in E Ecuador (Napo) uncertain, but probably centunculorum. Two subspecies recognized.
