The genus consists of 17 species, and despite the common name, not all of them display striping. Geographic range Species of Coniophanes are found primarily in Mexico and Central America, but range as far north as southern Texas in the United States, and as far south as Peru in South America. Description Snakes of the genus Coniophanes grow to a total length (including tail) of and are typically brown in color, with black striping down the sides and center of the back, and a red or orange underside. Some of the species, such as C. alvarezi, are solid brown. Habitat and behaviorConiophanes snakes are secretive burrowers. They spend most of their time digging into loose soils, forest leaf litter, or under rotting cactus. They are nocturnal, emerging from their underground retreats in the late evening to feed on frogs, lizards, small rodents, and smaller snakes. Reproduction Species in the genus Coniophanes are oviparous, laying clutches of up to 10 eggs in loose soil. The eggs hatch in around 40 days, depending on relative temperature and humidity. Hatchlings are about in length.
