Taxonomic note
The Inti Tanager described by Lane et al. (2021) from the lower Yungas of western Bolivia and southern Peru is sufficiently striking and genetically distinct to be given its own new genus. Monotypic.

Population justification: The population size has not been quantified. During the breeding season, the species is restricted to a small area in which it can reach exceptionally high densities, with twelve singing males being observed along a 2-km transect (Lane et al. 2021). Densities in the non-breeding range may be much lower (Lane et al. 2021).

Trend justification: The population trend has not been assessed. The only potential threat to the species is the loss and degradation of its habitat through human encroachment (Lane et al. 2021). Currently, tree cover loss within the range is very low (2% over ten years; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein) and large parts of the range remain in pristine conditions due to its inaccessibility. As the species moreover shows some tolerance of disturbed, open and secondary habitat, the population is suspected to be stable.
