Until recently, this species and T. chrysopterum, T. peninsulae and sometimes T. ngoclinhense were regarded as conspecific with T. erythrocephalum; those splits were made with prototype version of Tobias criteria, and are re-scored here. Differs from T. erythrocephalum and T. chrysopterum by its lack of dorsal maculation (3); dark primary-coverts (2); more extensive silvery-edged ear-coverts (1); broad, dark-streaked grey supercilium spreading onto neck sides (ns[1]); song with 2–3 notes and longer phrases (at least 3)#R. This arrangement may change, given report of hybrid between race connectens and T. chrysopterum ailaoshanense and fact that birds recorded in NE Myanmar, provisionally placed in T. chrysopterum woodi, might belong with nominate race of present species#R; further research required. Race ramsayi often merged with nominate, but seems sufficiently distinctive to warrant recognition. Racial identity of individuals in extreme S part of W Thailand uncertain; tentatively included in ramsayi. Five subspecies recognized.
