Until recently, this species and T. melanostigma, 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. melanostigma in characters given under that species, and from T. erythrocephalum by its maroon-rufous vs black chin and throat (3); unmarked vs boldly patterned ear-coverts (2); smokier-olive flanks (1); slightly lower-pitched voice (1)#R. After split, race woodi was initially retained in T. erythrocephalum, before race ailaoshanense was described; birds ­recorded in NE Myanmar might belong in T. melanostigma but provisionally included here with race woodi; further research required. Five subspecies currently recognized.
