Closest relatives may be T. clathratus, T. massena and T. comptus. Usually considered conspecific with T. melanurus, but differs in its white vs blackish iris (3); shining moss-green vs shining blue-green head and breast of male (2); grey on female below extending to mid-breast vs extending to lower breast in other taxa (hence more pinkish-red on female mesurus) (2); different song, “a slow, short series” vs “an often long-continued series”#R (2). Monotypic.

Distribution:

W Ecuador (S from Esmeraldas) and NW Peru (Tumbes, Piura).
