Hitherto treated as conspecific with T. anabatinus, but wing and tail much longer (effect size for male wing 4.25, tail 4.23, score 2); crown and upperparts darker, more olive (1); throat yellower (2); and loudsong takes longer to reach highest frequency (1), with usually more notes (ns[1]) and maximum frequency somewhat higher (1)#R. Three subspecies recognized.
