Not to much to say about this species. Everything online about these mites suggest they are predatory mites of the soil, feeding on thrips, springtails and other small critters. They are apparently also used as a form of biological pest control of other mites in reptile and amphibian enclosures.
What we do know about these guys is that like most soil inverts, for obvious reasons they dislike light, so recording them is difficult within a soil sample. We managed to separate one below but as you can see it clearly wanted to find shelter, escape the light and make it as difficult as possible to film and remain in focus.
