Subspecies
Phaethornis squalidus (Sibley and Monroe 1990, 1993) has been split into Dusky-throated Hermit (Phaethornis squalidus) and Streak-throated Hermit (Phaethornis rupurumii) following SACC (2005).
One of the small hermits sometimes separated in genus Pygmornis. Present species has the most primitive characters of any member of this group, linking these species with the larger members of genus Phaethornis. Often considered to include Streak-throated Hermit (Phaethornis rupurumii), but morphological characters indicate that that species is more closely related to Little Hermit (Phaethornis longuemareus) and Minute Hermit (Phaethornis idaliae).
Proposed subspecies "maranhaoensis", sometimes considered a full species, has proved to be the hitherto undescribed adult male plumage of Cinnamon-throated Hermit (Phaethornis nattereri).
