The Exploration of Trimeresurus Divided to Multiple Genera Based on Molecular Systematics

摘要

According to the contradictions about classification on Trimeresurus between " China's Fauna" and international database,the rationality about Trimeresurus divided to multiple genera based on molecular systematics was discussed. The genetic distance was calculated by sequencing 12S gene of the original Trimeresurus snakes,including 80 individuals of 33 species; and the molecular phylogenetic 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. The viewpoint that original Trimeresurus genera subdivided into 8 genera was more rational,and new authoritative reference books are expected to be published in China.
