Closely related to T. pompadora and its recently split allies; present species might be best considered as closest to T. griseicauda, T. teysmannii, T. floris and T. psittaceus, and all four of these have been treated as conspecific with present species or, rarely, with T. pompadora; species limits in this whole complex remain unclear. Numerous races have been described, based on minor differences of questionable significance. One or more of following are sometimes recognized: nipalensis (Himalayan foothills from Nepal E to NE India and mainland SE Asia S to N Malay Peninsula), hainanus (Hainan), erimacrus (W Philippines), chaseni (Selangor, in W Peninsular Malaysia), harterti (NE Sumatra), haliplous (Simeulue I), pegus (Nias I), smicrus (Batu Is, Mentawai Is), hypothapsinus (Enggano I) and nasica (Borneo). Treated as monotypic.


Nepal, NE India (E to Arunachal Pradesh, S to Mizoram and Odisha#R#R) and Bangladesh E to S China (W Yunnan, SW Guangxi#R, Hainan I) and S through Indochina and Malay Peninsula to Sumatra and surrounding islands, Deli I (S of W Java), Borneo and W Philippines (Mindoro, Palawan, Balabac).
