The white-tailed emerald was formerly placed with the coppery-headed emerald in the genus Elvira. A molecular phylogenetic study published in 2014 found that these two species were closely related to the snowcap in the monospecific genus Microchera.[3] The three species were therefore placed together in Microchera which has priority.[4]
