CommentAuthorship: the order of authors is different in the actual description and at the beginning of the paper, but there are the same authors. 
EtymologyThe species name, drukdaypo, was derived from the pronunciation of the Kham Tibetan word that means “dwarf dragon”, which describes the diagnostic dwarf-morphology of the new species. We name the new species using Kham Tibetan in honor of the local culture and people, as well as their positive impacts on wildlife conservation. Suggested English common name is: Dwarf Mountain Dragon, and the suggested Chinese common name is 1f (Pinying: Zhu Pan Xi).
