Subspecies
No subspecies.
This species (and, by extension, Tumbes Swallow (Tachycineta stolzmanni)), along with Tree Swallow (Tachycineta bicolor), Mangrove Swallow (Tachycineta albilinea), White-rumped Swallow (Tachycineta leucorrhoa) and Chilean Swallow (Tachycineta meyeni), sometimes placed in separate genus Iridoprocne, but DNA studies indicate close relationship of these taxa with clade consisting of Violet-green Swallow (Tachycineta thalassina), Golden Swallow (Tachycineta euchrysea) and Bahama Swallow (Tachycineta cyaneoviridis), and support placement of all in a single genus. Forms a superspecies with Tumbes Swallow (Tachycineta stolzmanni) and Mangrove Swallow (Tachycineta albilinea).
