Weird enough, Ernie, but glad you get them laying.
Now I have 5 Robo myself!! Supposedly 2.3.0, hopefully I will not see hemipenal bulges appearing on 2 of the "females", since they are quite small... a single one is about as large as the males, and quite sure about that. I don't know if 9cm snout-vent length is enough to be sure, but the other 2 "females" are only 7cm SV length- do you think it is still time to see them changing? Total length irrelevant, since all 3 females have regenerating tails.
About their adult length- I read about 15-17 cm- it is the SVL, or TL?
I saw once a documentary about Mongolia, and the guy traveling made a tent for the night. Well, for 2-3 seconds, in the night, a Gecko walked in front of his tent, and it was not too small- it's an old image for me, maybe wrong, but it had maximum 20cm. That one could be T. przevalskii, since they have max. 9,5cm "bodylength", as I read somewhere. They are not much different in size compared to roborowski, I think.
