Range DescriptionThis species occurs in southwestern China (Dulongjiang Valley, northwestern Yunnan) and northeastern Myanmar. In Myanmar, south of the Hukaung valley, it is found only east of the Chindwin River, with allied T. pileatus to the west (Pocock 1939). The situation in the Chindwin headwaters (Hukawng valley) is unclear, because animals show morphological variation suggesting the possibility of intergradation with T. pileatus and/or undescribed variation within T. shortridgei (Duckworth and Tizard pers. comm.). Morphologically typical animals also occur east of the Hukaung (Pidaung) and north almost to Hkakaborazi (Pocock 1939). It also occurs along the Dulong River in Gongshan District, Yunnan (Groves 2001).
