Question on Teratoscincus sp. identification

[raku_ubun]

Hi everyone, I am a newby here :biggrin:
I have recieved a pair of frog-eye gecko juvenile which are 5-6cm(svl) now caging together, both feed and behave well. It would me much appreciated if some expert can classify rather they are Teratoscincus przewalskii or Teratoscincus roborowskii?
Can you tell me the method to classify them as well, thank you very much

I am not an expert, but my guess would be Roborowskii, due to the spots and large scales.
Prezewalskii looks more small scaled and the pattern of the spots looks much smaller. But again, I am most definetly not an expert, and I might very well be wrong..
