Birds from S China (Sichuan, W Yunnan) described as race dulcivox (which has also been treated as synonym of C. fortipes davidiana), but type specimen lost; probably inseparable from intricata. The form described as “Phylloscopus subaffinis arcanus”, based on three specimens from W Nepal (in Jan and Apr), is now considered synonymous with nominate race of present species. Six subspecies recognized.
