The genetic distance was calculated by sequencing 12S gene of the original Trimeresurus snakes, including 80 individuals of 33 species ; and the molecular phylogenetie tree was established by taking Hypnale hypnale as the outgroup. The results showed that the topological structures of ME tree and ML tree were basically consistent, and all of the species in the molecular trees were divided into 8 branches; and the difference of T. albolabris between Hainan and other locations is not obvious.
