I found this one yesterday in one of my pitfall traps I've set up in the sort of scrubland forest I live in, semi-arid outside the rainy season, with a variety of flora from twisty oaks to mesquite to epiphytes to cacti to flowers of all kinds.
I think this roach is Arenivaga tonkawa but know that other species of the genus may be found in my general area.
I tried to brush/blow off the coco fiber substrate and get some better photos of their coloring and pattern in sunlight. Hope this helps with the ID! :)
