You are really on to something, JGeorge. Lampropeltis elapsoides was recently elevated to species status based on overwhelming genetic evidence in addition to the morphological and ecological evidence. In short, elapsoides doesn't intergrade with triangulum-complex animals anywhere. L. t. "temporalis" is likely a southern clinal variant of nominate triangulum or a post-glacial isolate of syspila, separated from the remainder of the syspila population by a northward expansion and ecological exclusion by L. elapsoides.
