Subspecies
One of the small hermits sometimes separated in genus Pygmornis. Similar to Buff-bellied Hermit (Phaethornis subochraceus) and Dusky-throated Hermit (Phaethornis squalidus), but morphological characters indicate a closer relationship to Reddish Hermit (Phaethornis ruber), White-browed Hermit (Phaethornis stuarti), Black-throated Hermit (Phaethornis atrimentalis), Stripe-throated Hermit (Phaethornis striigularis) and Grey-chinned Hermit (Phaethornis griseogularis). Recently described "Phaethornis maranhaoensis", which was considered a full species or a subspecies of Dusky-throated Hermit (Phaethornis squalidus), has proved to be the hitherto undescribed adult male plumage of present species. The two populations appear to be geographically isolated.
