d’Orbigny and Lafresnaye, 1837,
Yungas, La Paz, Bolivia.
Often considered conspecific with A. latinuchus, and both were originally considered part of a wider complex that included also A. terborghi and A. melanolaemus, although recent studies suggest that various components of this group may not be each other’s closest relatives. Has been suggested that all of these species, and A. schistaceus, are related in a complex manner, with yellow coloration lost or gained in a “leap-frog” pattern, such that taxa which do not look alike may in fact be closely related to each other. One specimen of present species from La Paz exhibits dark scalloping on breast, approaching A. melanolaemus; unclear if this is a variation in nominate race or due to gene flow between the two species. Name “Buarremon melanops” refers to specimens apparently assignable to nominate form of present species. Two subspecies recognized.
