Parabuthus villosus "Black" mating problem

[morslasdert]

Hi. I have adult pair of Parabuthus villosus "Black". I bought them 6 month ago, and I have never been able to mate them. The seller tried to plant them but doesn't know whether thereawere any successfull attempts.
Female is very huge and doesn't refuse food (eats one Zophobas motrio oncea week or two).
What I am doing wrong? Could the female be pregnant?
I

Are you providing a slab for the male to utilize?

That being said, she looks massive. Have you used a flashlight to candle light and see if she's already gravid (without removing her from the enclosure)?
