Range DescriptionThis species occurs at low and moderate elevations on the Atlantic slope from San Luis Potosi on the Gulf Coast of Mexico, to Bolivia and Brazil, and on the Pacific slope including the coast of Oaxaca, Mexico to lower Central America. It occurs through the base of the Yucatan Peninsula and northward through the Mexican state of Quintana Roo, apparently avoiding much of the drier western portion of the peninsula. In Guatemala this snake is known from near sea level to 1,000 m asl but may occur somewhat higher. In Mexico it occurs up to 1,200 m asl.
