Related Species

Described as Calothorax pulchra Gould 1859. Type locality "Oaxaca, in Western Mexico"; this is probably best interpreted as referring to the state of Oaxaca, and not to the city of the same name (Binford 1989: 339).

Calothorax pulcher is very similar to Calothorax lucifer (Lucifer Hummingbird), with which it forms a superspecies (Scott 1999).

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). Calothorax was not sampled as part of this phylogenetic survey, but is assumed to belong to the bee clade (McGuire et al. 2009). Genera that are documented as belonging to the bee clade are Archilochus, Calliphlox, Calypte, Chaetocercus, Myrtis, Rhodopis, and Selasphorus; additional genera, besides Calothorax, that probably belong to the bee clade are Atthis, Doricha, Eulidia, Mellisuga, Microstilbon, Myrmia, Tilmatura, and Thaumastura (McGuire et al. 2009).
