I agree, unless you have exact locality data of where that animal was collected it's nearly impossible to tell species apart from color alone. Do a scale count.
"Lystrophis semicinctus is predominately yellowish in coloration, with the pale areas between the black being of equal width. The width of the black and white rings remains constant to adulthood. Black rings vary from 14 to 22 pairs on the body and from 2 to 41/2 pairs on the tail.
The rostral is well developed, keeled dorsally, and upturned. Internasal scales are separated by the postero-dorsal portion of the rostral. Prefrontals are generally separated by an antefrontal shield in most cases; few individuals do not possess the antefrontal. The frontal is as long as it is broad. One preocular and two postocular scales are present. There is one loreal, and temporals measure 1 and 2. There are eight supralabials with the fourth and fifth entering the orbit. Of the ten infralabials, the first through the fourth are in contact with the first pair of chin shields. There are between 147 and 171 ventral scales; between153 and 167 ventral scales in females and 151 to 171 in males. The ventral plate is divided. Subcaudal scales measure 22-34 in females and 28-37 in males. Dorsal scales measure 21-21-17." Hognose.com
