The Bornean keeled green pit viper or North Philippine temple pit viper (Tropidolaemus subannulatus) is a pit viper species native to Brunei, Indonesia, Malaysia, and the Philippines.

Some localities have a mixture of light green to blue background colors.

The bands are variable and can be a combination of blue, red or white.

[2] Like many other arboreal snakes, this species has a disrupted green color to allow it excellent camouflage in the trees, hiding it from predators and prey.

The venom of T. wagleri is unusual among members of the subfamily Crotalinae as it is predominantly neurotoxic, with a much smaller percentage of hemotoxic venom peptides.
