Mites of this genus are associated with megalomorph spiders in Australia and Africa. It is not known if they are parasitic, but based on similar association, the probably are not parasitic. This species of an exotic mite from Africa is on an exotic tarantula from Africa. It probably cannot survive in Florida without the tarantula (Dr. W.C. 'Cal' Welbourn).
