Subspecies
Affinities within genus uncertain. Resembles Santa Marta Warbler (Myiothlypis basilica) in head pattern.
Proposed subspecies melanotis (described from Costa Rica) is treated as synonym of chitrensis, and perijanus (from Sierra de Perijá, in Venezuela) synonymized with auricularis. Recently described population in Serranía de San Lucas area of Colombian Andes may represent an undescribed subspecies, being brighter and more extensively yellow on underparts than auricularis.
