| Comment | |
| Etymology | Walker's statement of, " In allusion to its peculiarly Natrix-like pattern and stocky build, features which at first sight belie the true generic relationships, this gartersnake may be known as Thamnophis mendax" suggests that mendax was derived from Latin mentior ("I lie, deceive") + -āx ("inclined to"). |
