Baja California Sur, Mexico. September 2, 2013.
Sand snakes were the most common find while road-cruising at night in Baja Sur. This first one was found near the fishing town of Loreto. These snakes were formerly considered to be Chilomeniscus stramineus – it remains in the Chilomeniscus subgenus. In 2018, Sonora was elevated to a ‘supergenus’ containing Chilomeniscus, Chionactis, and Sonora as subgenera. For more information, see:
