Discosura is a genus of South and Central American hummingbirds in the family Trochilidae. The thorntails are sometimes placed in the genus Popelairia (Reichenbach, 1854), leaving Discosura for the racket-tipped thorntail. On the contrary, some have argued for merging this genus into Lophornis, which they overall resemble, except for the highly modified tail-feathers of the males.
Taxonomy
The genus Discosura was introduced in 1850 by the French naturalist Charles Lucien Bonaparte.{{cite book | last=Bonaparte | first=Charles Lucien | author-link=Charles Lucien Bonaparte | year=1850 | title=Conspectus Generum Avium | volume=1 | language=Latin | publisher=E.J.
