Eugenes spectabilis is monotypic.
Described as Heliomaster spectabilis Lawrence 1867; type locality Costa Rica
Eugenes spectabilis long was classified as a subspecies of Eugenes fulgens (Rivoli's Hummingbird), under the English name Magnificent Hummingbird. These two taxa now are recognized as a separate species "on the basis of differences in plumage commensurate with those between other sister species of hummingbirds" (Chesser et al. 2017).
Phylogenetic analysis of DNA sequence data, from both mitochondrial and nuclear genes, groups all hummingbirds into nine clades (McGuire et al. 2007, 2008, 2014). Eugenes is a member of what these authors called the mountain-gem clade (Lampornithini), together with Lamprolaima, Heliomaster, Panterpe, and Lampornis. Within this group, Eugenes is sister to Lamprolaima rhami (Garnet-throated Hummingbird); the Lamprolaima + Eugenes clade is sister to the clade of Heliomaster + Panterpe; and Lampornis is sister to the Lamprolaima + Eugenes + Heliomaster + Panterpe group (McGuire et al. 2014).
