Cardamon Mountains Green Pit Viper (Trimeresurus cardamonensis)

This slender Pit Viper I saw at a dry streambed at Koh Chang, Trat province, in April 2011 was, in fact, only described that same year. It's Cardamon Mountains Green Pit Viper or Trimeresurus cardamonensis, which is fairly new to science. This is a female. It is a small species and has been confirmed by a snake specialist contacted through Joe Hartman. Many thanks to you both.

 

Here's how I first found him. Unfortunately, as I approcahed to get close-up shots, he awoke from his slumber and decided to make a bid for freedom, but struggled to get over an enormous boulder.

Here he is now at full stretch, trying to escape the wrath of my camera lens.
