Either sphacelatus or

Either sphacelatus or prodromus. I can't see the pale hind margin to the pronotum that sphacelatus has. You usually find both species if you collect about 10, then the abbreviated stria character is easier to interpret.

8th stria

John, I've looked at 7 specimens and have found both sphacelatus and prodromus to be present. Once you get your eye in, the 8th stria is a very useful character in separating these two species.
