You were correct, thank you for correcting my ID. (I really need glasses yikes)

I don't see it, but I am colorblind and I don't see the reds you are referring too, therefore I could be wrong.I don't see any grey or blue on the underside. I will count the scales tonight to see if we have 19 or 21. thank you for pointing it out and hope you are well, and I will update the scale count here.

I see that uniform shade of yellow mainly on sirtalis. Elegans with yellow stripes are often more brownish or have different shades on their lateral stripes than their dorsal stripe. Also the red on the sides look like it's in small, neat squares completely surrounded by black on top and sitting right above the lateral stripes. Red on elegans is usually either much more prevelent than the black or is much messier, with stray speckles or small blotches all over, including on the lateral stripes and the ventral region. Even lots of elegans that lack any red on top will still have some red speckling on the underside so that totally plain and light creamy ventral also points towards sirtalis. Head shape and scaling would be the clincher so it's a bummer that got smashed so bad.

Hmm I am not so sure, but I do have the specimen. What makes you think sirtalis?

Looks like a sirtalis
