Range DescriptionThis species is found in the Cumberland and Upper Tennessee River drainages in Tennessee and Kentucky, USA (Williams et al. 2007), with anecdotal reports from Virginia (Winston et al. 1997). Based on taxonomic uncertainty, however, it may be confined to the Cumberland River basin upstream of Pine Mountain with questionable records from Tennessee and Virginia as potentially an alternate and as yet undescribed species of this genus (R. Thoma pers. comm. 2009). The extent of occurrence of this species has been estimated around 5,700 km².
