I don't know about gloydi, but I asked a similar question regarding the differences between H. nasicus nasicus and H.n. kennerlyi in a previous post. As of yet I don't believe that there have been any DNA comparison between H.n.n and H.n.k. I believe they are separated based on physical appearance alone w/ H.n.k.being the smaller of the two, and having 6 head scales as opposed to H.n.n.'s 3. I don't know if anyone is doing studies in the locales in TX and NM where their ranges possibly overlap. Oh, to have time, gas and alot grant money. Happy herping.
