Closely related to T. schistogynus and formerly treated as conspecific. In recent genetic analysis, present species exhibited deep genetic divergence among populations, but monophyly confirmed in COI barcodes#R. Race simillimus sometimes subsumed, but here accepted on basis of male’s darker plumage and small white interscapular patch. Five subspecies recognized.
