The plumeleteers are a genus Chalybura of Neotropical hummingbirds in the family Trochilidae.
The genus Chalybura was introduced in 1854 by the German naturalist Ludwig Reichenbach. He listed three species in the new genus but did not specify the type species. In 1879 Daniel Giraud Elliot selected Trochilus buffoni Lesson, the white-vented plumeleteer, as the type. The genus name combines the Ancient Greek ÃÂñûàÃÂ/khalups meaning "steel" with -ÿàÃÂÿÃÂ/-ouros meaning "-tailed".
A phylogenetic study published in 2014 found the genus Chalybura containing the plumeleteers was sister to the genus Thalurania containing the woodnymphs.
The genus contains the following two species:
