Subspecies
No subspecies.
Tachycineta albilinea (Sibley and Monroe 1990, 1993) has been split into Mangrove Swallow (Tachycineta albilinea) and Tumbes Swallow (Tachycineta stolzmanni) following SACC (2005).
This species (and, by extension, Tumbes Swallow (Tachycineta stolzmanni)), along with Tree Swallow (Tachycineta bicolor), White-winged Swallow (Tachycineta albiventer), 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 White-winged Swallow (Tachycineta albiventer). Birds from north-western Mexico (Sonora) sometimes separated as subspecies rhizophorae, but variation not constant.
