[Herpetology • 2012] Dendrelaphis nigroserratus • A New Species of Dendrelaphis Boulenger, 1890 (Squamata: Colubridae) from Thailand and Myanmar


Dendrelaphis nigroserratus

Abstract
A new species of the colubrid genus Dendrelaphis Boulenger 1890 is described. Dendrelaphis nigroserratus sp. nov. occurs in a part of West Thailand as well as in the extreme south of Myanmar. Morphologically, D. nigroserratus sp. nov. is similar to D. cyanochloris (Wall, 1921) with which it occurs sympatrically. It is distinguished from the latter by its highly conspicuous neck coloration, high incidence of paired postparietal shields and its much larger size. In coloration, it resembles
D. striatus (Cohn, 1906) from which it is distinguished by several aspects of its morphology. The discovery of D. nigroserratus sp. nov. underscores the notion that the hilly western parts of Thailand are in need of further exploration.

Key words: Dendrelaphis cyanochloris, Dendrelaphis nigroserratus sp. nov., Dendrelaphis striatus, Indochina, Southeast Asia, taxonomy




Proposed Thai name: ngu sai man kho dok lueai si dam – งูสายม่านคอดอกเลื่อยสีดำ, งูสายคอฟันเลื่อย
