Interesting questions.
I can tell you that in Durango, MX, just west of Ciudad Durango in (lower) elevation Chihuahuan Desert you have affinis (just like in Texas affinis, atrox, Heterodon, & Coachwhips), and a few miles west at a higher elevation and different habitat/life zone you have deppei deppei and that there is an excellent chace for overlap. I would bet that they do indeed overlap/ mix.
