The L ruthveni and L m thayeri were all field-collected in the late summer of 1980. The ruthveni were typical for the species and location. The thayeri was similar to the snake you have that is in question. These are the escapes which I have personal and intimate knowledge of. I will look through my old photo prints for the Bob Mackin "Pepper's Hill" specimen. I viwed and handled the snake in person following its capture and my impression at the time was that it was an unusual individual in that the head and snout markings were reduced, but it was, in fact, a triangulum. Other escaped kingsnakes were related to me by Bob Mackin. Since he collected many locations while traveling to Big Bend, he often brought with him triangulum ssp. from Utah, Arizona and S Texas. Enevitably, some of these got loose and were never found..so who knows. As Mike Chambers indicated in his post, there were other individuals who imported exotic triangulum subspecies to the area and subsequently "released" them to the wild, but I only know of this second hand. Your idea to try to determine the phylogeny of your specimen via microsatellite DNA analysis is good, although based on a such a small sample (1 specimen) may prove difficult to be conclusive. I may be able to provide samples from wild L mexicana if you wish. Let me know if I can be of further assistance.
