Naming
The taxonomy of this species and the long-tailed hermit is confusing. Most taxa previously consider subspecies of the latter are now considered subspecies of the former.A satisfactory taxonomic treatment of the entire "P. longirostris/P. superciliosus/P. malaris" group is still lacking according to some Neotropical ornithologists. Additionally, the taxon "margarettae" of the Atlantic Forest of eastern Brazil is sometimes considered a separate species: Margaretta's Hermit.
