Overview
The Chihuahua Mountain Kingsnake is a Mexican endemic restricted to the higher elevations of the Sierra Madre Occidental in Chihuahua and adjacent areas. It was formerly grouped with other mountain kingsnakes before being recognized as a distinct species.
Its tricolor banding provides camouflage among forest litter while also serving as a possible mimic of venomous coral snakes sharing its range.
How to identify it
- Bands of red or orange, black, and cream/white circling the body
- Smooth, glossy scales
- Small, rounded head with round pupils, not triangular
- Slender, cylindrical body form
- Look-alikes: coral snakes and related mountain kingsnakes; subtle differences in banding proportions distinguish species within the complex
