Mexico = Jalapa, Veracruz.
Often placed in genus Buarremon or Atlapetes. A. kuehnerii was described, as a new species, from highlands of Guerrero, W Mexico, solely on basis of DNA, being otherwise identical to specimens of race suttoni#R, with which it is here provisionally considered synonymous. Race apertus proposed for treatment as separate species#R, but shares blackish tail and lack of tawny-yellow supercilium with race alleni, and song not different from brunneinucha, unlike more southern races#R. Proposed race nigrilatera (no specimens examined in present review), described from Cerro Baúl (extreme SE Oaxaca), in S Mexico, considered synonymous with suttoni (in HBW and some other checklists#R) but seems more likely on biogeographical grounds to be part of macrourus, if it is not in fact recognizable. Nine subspecies currently recognized.
