Subspecies
Atlapetes atricapillus and Atlapetes torquatus (Sibley and Monroe 1990, 1993) have been lumped as torquatus and moved to the genus Buarremon following SACC (2005). The genus Arremon has been expanded following SACC (2007) to include the genera Arremon, Buarremon and Lysurus.
Until recently was often placed in genus Buarremon (or Atlapetes), and considered conspecific with White-browed Brush-finch (Arremon torquatus), Arremon costaricensis, Arremon basilicus, Arremon perijanus, Arremon assimilis, Arremon phaeopleurus and Arremon phygas. Recent molecular data indicated that this group was sister to present genus, while other Buarremon might be more closely related to another genus then used, Lysurus, rendering Buarremon polyphyletic. The decision was therefore made, on basis of similarities in molecular data, plumage, voice, behaviour and micro-habitat, to subsume Buarremon and Lysurus in present genus. In addition, molecular and morphological data indicated that all members of above-mentioned group should be treated as separate species.
The following 2 subspecies are recognised:
tacarcunae (Chapman, 1923) - Eastern Panama (lower subtropical zone eastern from Panamá province).
atricapillus (Lawrence, 1874) - Northern Colombia in west, central and eastern Andes.
