Known only from Caney Fork River drainage, Tennessee (including the counties Grundy, Van Buren, Warren and White). However, it does not occur in the portion of the Caney Fork in the Cumberland Plateau physiographic region, including (approximately) the main river upstream of Gastens Branch in White County and Cane Creek upstream of Tennessee Highway 30 in

Van Buren County. Habitat degradation from intensive silviculture, livestock production, invasive species, and urbanization in the area could further reduce the range and abundance of these endemic species (Ref. 93269).
