L.t.arcifera and L.ruthveni have a convoluted history. Long story short, what we once called "Jalisco Milks" in the hobby have recently been found to be L.ruthveni from a population in Jalisco, Mexico. The only true L.t.arcifera in the US (probably) are Laguna de Capala (Lake Chapala) locality animals that Bob Applegate formerly worked with. I believe Shannon has a breeding colony of them now. Differences in scalation, coloration, genetic make-up, and hemipene morphology are used to tell the two species apart. A more detailed description of the arcifera/ruthveni history is found on the sierraherps website (link off of the kingsnake.com main page), dedicated to mexicana complex kings.
Hope this helps
