Helicops angulatus — Banded South American Water Snake
Some other names for this species:
Brown-banded Water Snake, Broad-banded Water Snake, Aquatic Hunter Snake, Mountain Keelback Water Snake
This is a common aquatic snake in Peruvian Amazonia, and our group saw several of them. This fairly drab individual was the only one I personally saw in the wild though. It was stretched across a sidewalk that runs along the river's edge and past at least one village. The sidewalk is colloquially called a "Fujimori sidewalk" because it was one of many built as part of a fairly blatant effort to buy support among rural villagers for past president of Peru Alberto Fujimori.
