This species is known from two caves in Benton County, Arkansas, USA (Hobbs 1989, Robison and Allen 1995) and just into Missouri (Graening et al. 2006). With all of the effort to look for cave organisms based out of Fayetteville, a great deal of search has been focused in the area to find further specimens of this species. It has long seemed confined to the original caves, yet recent discoveries have added 2 additional sites nearby - both based on one or two specimens. In Missouri, expert survey work has been carried out with no further discoveries of the species in that state (Brian Wagner, AR Game and Fish, to Cindy Osborne, AR Heritage, pers. comm. 2002). The area of occupancy (AOO) is estimated to be less than 4 km².
