R.Extensicollis Info?

[mnyabi]

I have been looking into getting into Mantids soon and come across R.Extensicollis but I am having a very hard time finding any information on them. How big do they get? Do they like it humid or dry? Any other information would be great before I decide what to get.

Their care is more or less the same as a Megaera or a Basalis. They get little more than 3 inches and like it a little more on the humid side.
