First, welcome to the forum.
How long have you been working with scorpions?
There is a paper, a research paper, published in Euscorpius, in 2008, on the species (http://www.science.marshall.edu/fet/euscorpius/p2008_70.pdf). Naturally, it's not a care sheet, but it covers the habitat range. I noticed that you commented on one of Michiel's posts from several years back. He is still working with scorpions, but also has a lot on his plate. At any rate, R. pintoi was initially classified as a subspecies of R. laticauda in 1932, then synonymized into R. laticauda in 1982, before finally becoming an independent species in 2006.
