As for lepidus in the Huecos, if you go by the color pattern characters that Gloyd used to describe klauberi, those tan clean banded beasts from the south end of the Huecos are as pure a klauberi morph as any you'll find.
However, those characters that he did use do not hold up under scrutiny. For instance, as you move way west, using those characters, the great majority of Huachuca and Santa Rita (Arizona) Mountain individuals would key out to lep. lep.
Attempting to apply color pattern for taxonomic use in the lepidus group is about as useful as it is in the alterna group: not very useful at all (please note the clever tie-in to alterna to keep this post appropriate to this forum). I've examined several hundred museum specimens range-wide, and seen hundreds more in the field. There some trends that hold up, and some very clean populations here and there, but as a species they are so polymorphic within and between populations that it will drive one to despair trying to make taxonomic sense out of it.
