Psammodynastes pulverulentus, the common mock viper, is a species of snake native to Asia. It is one of the few snake species to possess three hemipenes.

The common mock viper is known from Bangladesh, Burma, Cambodia, China (Fujian, Yunnan, Guangxi, Guangdong, Hainan), Hong Kong, NE India (Assam, Sikkim, Darjelling;Jalpaiguri; Meghalaya, Arunachal Pradesh), Bhutan, Indonesia (Bali, Bangka, Borneo, Butung, Enggano, Flores, Java, Kalimantan, Komodo, Lombok, Mentawai Archipelago, Natuna Archipelago, Padar, Riau Archipelago, Rinca, Sangihe Archipelago, Sulawesi, Sula Archipelago, Sumatra, Sumba, Sumbawa, Togian Archipelago), Laos, Malaysia (Malaya and East Malaysia, Pulau Tioman), Nepal, the Philippines (Balabac, Basilan, Bohol, Bongao, Busuanga, Dinagat, Jolo, Leyte, Luzon, Mindanao, Negros, Palawan, Panay, Polillo, Samar), Taiwan, Thailand (incl.
