Hey all, I'm collecting fish down in Mexico (Sierra Madre of Hidalgo) and found this guy under rock. Was pretty Only about 10 or so inches. Really peaceful but not too keen on hanging around. The neighbor who was with me said they call them something like zochimiagual or xochimiagual. I have no idea of the spelling. A friend thought it could maybe be a Leptodeira annulata? Just thought I'd share
