Looking at the dorsal, it looks like an LMB. The soft and spiny parts look almost separated, while in a Guadalupe and spotted, they look connected (taller/less variation in size of dorsl spines).
Now agreed. I took a closer look at the dorsal. It looked connected to me at first, and the spots(blotches) on the side seemed to be too vertically elongate to be LMB. Oh well, I guess I need to start being more observant.
