In Kentucky, it is restricted to Roaring Paunch Creek proper in McCreary County (Taylor and Schuster 2004). In Tennessee it occurs in the Cumberland Plateau province, from three localities in the Big South Fork Cumberland River including Perkins Creek and Roaring Paunch Creek in Scott County (Williams and Bivens 2001). Recently in a survey of Tennessee (Williams et al. 2002), it was found in Perkins Creek (type locality), a headwater tributary to Perkins Creek, and Roaring Paunch Creek, but also from 3 new stream localities: Isham Creek, Jones Branch, and Otter Creek. The estimated extent of occurrence (EOO) of this species is just under 1,900 km2.
