Taxonomy and species list
These two species were formerly placed in the genus Leucippus. A molecular phylogenetic study published in 2014 found that Leucippus was polyphyletic.[1] To resolve the polyphyly these two species were moved to the resurrected genus Thaumasius that had been introduced by Philip Sclater in 1879 with the spot-throated hummingbird as the type species.[2][3]
