The Mexican woodnymph was formerly placed in the genus Thalurania with other species with "woodnymph" in their English names. A molecular phylogenetic study published in 2014 found that Thalurania was non-monophyletic and that the Mexican woodnymph is closely related to species in Eupherusa. Based on this result the Mexican woodnymph is now placed in Eupherusa.
