Sibon sanniolus sanniolus
Campeche, Mexico. July 1, 2016.
In The Amphibians and Reptiles of the Yucatán, Julian Lee indicates that the specific sanniolus derives from the Latin sannio, “one who mimics”, “clown”, or “buffoon”. I’ve seen several of these small snail suckers on the roads at night. I can’t seem to get decent photos of them – they come across as flat and featureless, and that seems to be the case for most of the Sibon and Dipsas speces that I’ve encountered.
