The common mock viper is a small snake native to Asia, with a total length up to 65cm, shorter in males. When threatened it forms defensive coils and strikes in a viper-like fashion, though it is harmless to humans (Wikipedia, general species account).
The Reptile Database summary lists Bangladesh, Myanmar, Cambodia and China (Fujian, Yunnan, Guangxi, Guangdong, Hainan), and that list as shown does not include Bhutan, so the Bhutan record is flagged for checking. No habitat, diet or breeding information was found.
