Pygochelidon is a genus of birds in the swallow family Hirundinidae that occur in the Neotropics.


The genus Pygochelidon was introduced in 1865 by the American naturalist Spencer Fullerton Baird with the blue-and-white swallow as the type species.[1] The name combines the Ancient Greek pugē meaning "rump" with khelidōn meaning "swallow".[2]

This genus was formerly treated as a junior synonym of the genus Notiochelidon.[3] It was resurrected to contain a clade of two species based on a genetic study published in 2005.[4][5]


The genus contains two species:[5]
