Paratettix aztecus?

I'm wondering if this is Paratettix aztecus. I added a close-up of the head (dorsal view). Here's the part of "Grasshoppers of California" key that's relevant to telling apart Paratettix from Tetrix:

1 Fastigium from dorsal aspect broad, wider than
width of eye, extended forward beyond the eyes,
its front margin convex . . . Tetrix 2

Fastigium from dorsal aspect narrow, no wider than
width of eye, not extending forward beyond the
eyes, its front margin truncate. Paratettix 4

It doesn't look like P. mexicanus ("Lower margin of middle femur distinctly lobed"), so that leaves P. aztecus. I see there's one in the guide from Angelo already.

I compared Paratettix vs Tetrix Essig specimens... this does seem like Paratettix to me... but I'm not familiar enough with these guys to be sure of anything. The head does look different from this pygmy grasshopper I photographed.

This one slipped through the cracks for me. Looking at the pygmies I photographed on our last outing, I agree on P. aztecus (there were both P. aztecus and P. mexicanus out there).

Thinking Tetrix subulata on this one too.
