Many accounts are incomplete although new information is being added continuously.
Errors do occur. Users are cautioned to refer back to the original cited source to assess completeness and correctness before using the information. Web updates are intermittent, not continuous, therefore some dynamic information such as legal status may not be absolutely current. The gray-banded kingsnake has at various times been described as a subspecies of Lampropeltis mexicana, but is currently afforded specific status as a close relative of L.mexicana, which is found south of the anticline of Arteaga, and L.ruthveni, which is a montane form from central Mexico. The only scientific specimen of L.alterna from New Mexico was collected by Gary Swinford in Walnut Canyon, Guadalupe Mountains, Eddy County, New Mexico.
