I see that my subject has attracted considerable investment from you and I thank you warmly. by reading all your posts I can conclude several things, color and appearance dispute over his body (speck, positioning lines) are identical to Thamnophis Proximus like pictures of this website : Thamnophis proximus pictures

I had a doubt made the differance in the number of scales in his mouth but you have explained to me that this could be the case in the same espèce.Donc I think that consolidating all of your message can be said with high probability Thamnophis Proximus for subspecies or it is Orarius Proximus is or may be an intergrade.

I thank you all and I think is great forum with people interested in everything and I like it very much.

Ps/none of you had pictures of garter sauritus which corresponds to my snake. Finally, I hope it will break if a party's reasoning.
