Waray Dwarf Burrowing Snake occupies its own branch on snake tree of life.

To be fair, the newly described Waray Dwarf Burrowing Snake (Levitonius mirus) is pretty great at hiding.

In its native habitat, Samar and Leyte islands in the Philippines, the snake spends most of its time burrowing underground, usually surfacing only after heavy rains in much the same way earthworms tend to wash up on suburban sidewalks after a downpour.
