Subspecies
Sometimes placed in monospecific genus Taphrospilus. Alternatively, in past, sometimes placed with Spot-throated Hummingbird (Leucippus taczanowskii) and Olive-spotted Hummingbird (Leucippus chlorocercus) in Talaphorus.
Proposed subspecies peruvianus fits well into overall pattern of variation within the species, so subspecific status cannot be maintained.
