Other common names: Curve-winged Hummingbird/Sabrewing (curvipennis); Long-tailed/Tuxtla Sabrewing (excellens)

Taxonomy: Trochilus curvipennis Lichtenstein, 1830, Mexico.
In past, sometimes separated in genus Pampa. Race excellens considered by some to be full species; research required in zone of hypothetical contact. Race pampa has also been treated as separate species, based mainly on shorter bill, but behaviour and voice similar to those of nominate. Subpopulation of Yucatán Peninsula sometimes regarded as race yucatanensis, but doubtfully distinct. Three subspecies currently recognized.
