摘要：Sexual dimorphism（SD） and geographic variation（GV） are widespread in snakes. Protobothrops mucrosquamatus（Cantor 1839） is one of the most common Asian venomous snakes with a wide geographical distribution. We examined SD and GV patterns for this species by using multivariate statistical analyses of external morphological characters scored from specimens from the China’s mainland. The result displayed that SD was significant in several external characters in P. mucrosquamatus, and the male P. mucrosquamatus formed two distinct clusters（Hainan Island and China’s mainland）, but the females did not. Based on our present work and the other data, we concluded that no significantly intraspecific differentiation is present within this species.
