Initially described as a race of A. fuliginosa#R, and until very recently#R considered conspecific with A. vilcabambae, but differs in its richer, darker rufous throat (2); more uniform underparts with much-reduced soft white edges to feathers, so that effect of light scaling is almost lost (1); slightly blacker lores and adjacent areas of face (1); slightly less obvious supercilium (ns[1]); and evidently different song (2) and call (2). Scores for vocal differences could be much higher, but many Asthenes have one of two song types while at least one species has both, with a similar situation for call types; in this case, therefore, considerable caution is called for, and ideally a larger sample is needed in order to confirm that apparently different song types are not shared#R. In addition, DNA data#R indicate that ayacuchensis is closer to A. palpebralis and A. ottonis than to A. vilcabambae. Monotypic.

Status and conservation

Not globally threatened (Least Concern). Population unknown, but presumably small. Overall range estimated at 17,200 km², although its Area of Occupancy is perhaps just 500... read more
