fulgens (Swainson 1827); type locality Temascáltepec, Mexico)
Occurs from the southwestern United States south to northeastern Nicaragua.
See Detailed Description.
spectabilis (Lawrence 1867); type locality Costa Rica
Occurs in Costa Rica and Panama.
This subspecies is similar to nominate fulgens, but is larger (see Measurements). The male has the breast dull metallic green, and the undertail coverts are more greenish or bronzy brownish gray, margined with paler buff (Ridgway 1911). The female is similar to female fulgens in plumage, but the outer rectrices are more narrowly tipped with darker brownish gray.
The southern subspecies, spectabilis of Costa Rica and Panama, formerly was recognized as a separate species (e.g. Ridgway 1911).
The species fulgens is the sole species in the genus Eugenes.
Phylogenetic analysis of DNA sequence data, from both mitochondrial and nuclear genes, groups all hummingbirds into nine clades (McGuire et al. 2007, 2008). Eugenes is a member of what these authors called the mountain-gem clade (Lampornithini), together with Heliomaster, Panterpe, and Lampornis. Within this group, Eugenes is basal to Heliomaster + Panterpe, and Lampornis is sister to the Eugenes + Heliomaster + Panterpe group.
