Three subspecies recognized. Geographic variation is described as "slight" (Schuchmann 1999), and is expressed primarily in variation in size, with the smallest populations at the northern and southern ends of the distribution of the species:
koepckeae, Berlioz 1975
Known with certainty only from the type locality, at the Cerro Illescas, in southwestern Piura, Peru
Similar to nominate vesper, but smaller; bill shorter and more slender; and the pale patch on the rump is less developed (Schuchmann 1999).
vesper, described as Ornismya vesper Lesson 1829; type locality Chile
Occurs from northern Peru (other than the range of koepckeae) south to northern Chile in Tarapacá.
See Detailed Description. Includes tertia Hellmayr 1932 (type locality Tembladera, Cajamarca, Peru).
atacamensis, described as Trochilus atacamensis Leybold 1869; type locality Quinta de Sápulen, Copiapó, Chile
Occurs in northern and central Chile, from Atacama south to Santiago.
Similar to nominate vesper, but smaller, with a shorter and more slender bill (Schuchmann 1999).
The genus Rhodopis was proposed by Reichenbach 1854, with Ornismya vesper as the type species, and is monotypic.
Phylogenetic analysis of DNA sequence data, from both mitochondrial and nuclear genes, reveals that hummingbirds (Trochilidae) constitute nine major clades, comprising the hermits, mangos, Patagona, topazes, coquettes, brilliants, mountain-gems, bees, and emeralds (McGuire et al. 2007, 2009, 2014). Rhodopis is a member of the bee clade (McGuire et al. 2007, 2009 2014). Other genera that belong to the bee clade are Tilmatura, Calliphlox, Thaumastura, Myrmia, Myrtis, Eulidia, Chaetocercus, Microstilbon, Doricha, Archilochus, Mellisuga, Calypte, Atthis, and Selasphorus; Myrtis and Rhodopis are sister taxa (McGuire et al. 2007, 2009, 2014).
