Known from the upland streams on the Cumberland Plateau, restricted to small streams in the upper Bear Creek system (Tennessee River drainage) and the Hubbard Creek system (Mobile Basin) above Kinlock Falls in Franklin, Lawrence, and Winston counties, Alabama. Inundation of the Upper Bear Creek Reservoir, which was constructed in 1978, seems to have extirpated this species in the downstream portion of the upper Bear Creek system based on historical data.
