Distributions of identified records of taxa (as defined herein) of the Z. mollissima complex (Z. dixoni not shown), based on verified specimens, photographs, sound recordings and genetic samples. a Alpine Thrush Z. mollissima sensu stricto (including whiteheadi, synonymized herein) and localities for verified genetic samples of “Yunnan Thrush” Z. mollissima(?). b Himalayan Forest Thrush Z. salimalii sp. nov. and Sichuan Forest Thrush Z. griseiceps. Filled black symbols represent records from June to August, filled grey from April to May and September to October and open  symbols from November to March. Multiple site records are not indicated; where multiple records exist from different seasons, site seasonality codes mapped are those during or closest to the breeding season. Labelled provinces and states are those referred to prominently in the text in reference to particular records and/or taxa. The Manipur specimen localities for the Himalayan Forest Thrush could not be traced, so the symbol is arbitrarily located in the center of the western Manipur hill range
