Philodryas argentea Green-striped Vine Snake
Some other names for this species:
Striped Sharpnose Snake, Diurnal Vine Snake, Lance-headed Vine Snake, Daudin’s Vine Snake
This species has bounced around between Oxybelis, Xenoxybelis, and Philodryas in the past couple of decades. Following The Reptile Database, I'm putting it in Philodryas for now.

Green-striped Vine Snake (Philodryas argentea)
William Sargent spotted this small sleeping striped snake after the local guides had overlooked it. When first seen, the snake's head was not visible, but as we started taking photos it slowly lifted its head and peered suspiciously at us.

Green-striped Vine Snake (Philodryas argentea)
I found this coiled rope of a snake on a night hike with local guide Emerson and reserve caretaker Julio, after the two of them had passed it by. I was very proud.

A rainforest-worthy storm had ended only a few minutes before I found this drenched vine snake.
