Range Description

This species was first found in a tributary of Dry Creek, at Pea Ridge Wildlife Management Area in De Kalb County, Tennessee, USA. It has since been found to occur in a portion of the Eastern Highland Rim in central Tennessee. It appears that this species is restricted to a narrow peninsula (14 km) of elevated limestone that extends southwards throughout the counties of De Kalb and Cannon (Taylor et al. 2006). Samples made in several high gradient, seep-fed, creeks in nearby Eastern Highland Rim sites surrounding the peninsula previously described did not record this species (Taylor et al. 2006). The area of occupancy (AOO) of this species is estimated to be less than 20 km2.
