Has been placed with T. albilinea (and, by extension, T. stolzmanni), T. albiventer, T. leucorrhoa and T. meyeni in separate genus Iridoprocne. DNA studies, however, indicate close relationship of these with clade consisting of T. thalassina, T. euchrysea and T. cyaneoviridis, and support placement of all these taxa in a single genus.
