Description
The Mexican kingsnake is a smooth-skinned, slender, sub-cylindrical snake which is more flattened ventrally than most members of the genus Lampropeltis. It has a wide head, large eyes and a long tail. Adults grow to a length of about 80 cm (31 in). This snake has broad red saddle-shaped markings, bordered with black and separated by cream, brown or pinkish bars. The sequence of colors does not vary but the proportions and shades of the color bands are quite variable. The nominate subspecies has distinctive red markings and intricate patterning on its head while L. m thayeri has a plain head, narrower red saddles and broader, usually cream-shaped bars separating them.
Distribution and habitat
The Mexican kingsnake is endemic to northeastern Mexico. The nominate subspecies is found in the state of San Luis Potosí and L. m thayeri is found in the state of Nuevo León. The typical habitat of this snake is rocky hillsides, valleys and deserts in mountainous regions as well as woodlands, oak forests and grassy areas. Its altitudinal range is 1,300 to 2,400 m (4,265 to 7,874 ft) above sea level.
Behavior
The Mexican kingsnake is a secretive, nocturnal species that is seldom seen, hiding under rocks and fallen trees by day. It feeds on reptiles, small mammals and amphibians, but its main prey is diurnal lizards. It is oviparous and lays a clutch of three to five eggs.
Status
The IUCN has listed the Mexican kingsnake as being of "Least Concern". This is because it has a wide range and the population is presumed to be large and seems to be stable. It is sometimes misidentified as a venomous coral snake and killed by humans but it otherwise faces no major threats. Part of its range occurs within the confines of the state of Santa Rosa protected area.
