A new species of pit-viper from the Ayeyarwady and Yangon regions in Myanmar (Viperidae, Trimeresurus)

In a genomic study by Chan and colleagues, pit-vipers of the Trimeresurus erythrurus – purpureomaculatus complex from the Ayeyarwady and Yangon regions in Myanmar were demonstrated to be a distinct species based on robust population genetic and species delimitation analyses. Here, we provide morphological characterizations and a formal description of those populations as a new species. The new species, Trimeresurus ayeyarwadyensis sp. nov., is most closely related to T. erythrurus and T. purpureomaculatus and shares morphological characteristics with both of those species. Some specimens of T.... Mehr ...
