Parabuthus mossambicensis max size

[Cecropia1999]

I have been seeing this species of parabuthus called P. mossambicensis recently become more common in the hobby. However, all of the ones for sale are super small, as in 2nd or 3rd instar max. Compared to adult P. Villosus or P. Transvaalicus, how big to adults of this species get? Has anyone kept this species before?
