When I selected “scientific name” and typed in “Drymarchon”, here’s what I got:ĭrymarchon Fitzinger, 1843 – valid – Indigo Snakesĭrymarchon caudomaculatus Wüster, Yrausquin and Mijares-Urrutia, 2001 – validĭrymarchon corais (F. Wondering what the deal was, I went to our go-to taxonomic source, the Integrated Taxonomic Information System ( ). I always thought the Eastern and Texas Indigos were subspecies of the same species. The US Fish & Game Wildlife Service places the Eastern Indigo as a subspecies, couperi, of the species Drymarchon corais. And did you notice that Texas Parks & Wildlife called our Indigo a subspecies of the Eastern Indigo? Our Indigo, according to the State of Texas, is a subspecies, erebennus, of the species Drymarchon melanurus. Did you notice the difference in the names? Our Indigo, apparently Drymarchon melanurus erebennus, was not listed. So, in an abundance of caution I also checked the US Fish & Wildlife Service where, lo and behold, I found the Eastern indigo snake ( Drymarchon corais couperi) listed (see ).

Then, I went to another Texas Parks & Wildlife page: Here’s a link to the listing, check it yourself: First, I searched the Texas Parks and Wildlife website and didn’t find the Texas Indigo Snake listed as either threatened or endangered. I, too, thought it was considered threatened by both the State of Texas and the US Government. They are non-venomous and have been declared as a threatened species by the US state of Texas.” Note the “threatened” status. Many online resources say something similar to what says, “Found in Texas and almost everywhere in Mexico, the Texas Indigo Snake is a large size snake that is a member of the colubrid family. But first:Ī DISCLAIMER (well…maybe, you’ll have to read more to find out what is it)!
