Roach Nymph ID - Possible Escape!

[Tenevanica]

I was in my rearing room this morning, and I found this guy crawling across my floor. I don't have roaches in my house, and it doesn't match any of the common pest species. It must be an escape then! The problem is, I don't keep any species with nymphs that resemble this one. I did a little test, and I've determined it can climb. My (non-hybrid supposedly) Gromphadorhina portentosa show this coloration in larger nymphs, But, it's just under a centimeter long, and hisser nymphs don't get that color until later on in their development. Please help me, because the sooner I can identify the species, the sooner I can fix the escape problem!
