The distribution of the capped langur (Trachypithecus pileatus) in China is still controversial since Shortridge’s langur (T. shortirdgei) was upgraded to a full species. Shortridge’s langur was considered mainly distributed in west Yunnan Province, China and northeastern Myanmar. Based on our field survey, we found strong evidence for the existence of the capped langur in China and the new distribution range of Shortridge’s langur in Tibet. The capped langur is a new record for China, and Shortridge’s langur is new records for the Tibet Autonomous Region. The extended ranges of the capped and Shortridge’s langur in the southern Himalayas illustrate that the langur species of gray langurs and lutungs may have a close relationship.
