The Oaxacan Pygmy Rattlesnake is a small species of rattlesnake found in the mountains of Oaxaca. This species can be distinguished from the two other species of Mexican Pygmies by its 5-8 tail bands and undivided parietal scales (behind the eyes). It inhabits mixed oak-pine forests and semi-arid scublands. As a generalist predator, it eats a variety of prey including rodents, lizards and sometimes insects.
This species is threatened by habitat loss, particularly the use of fire to clear woodlands for agriculture. Human persecution also plays a role in the decline of this species.
