Range and habitat

It is found only in the United States, within the Clinch and Powell rivers. It is likely extirpated from the Holston River, having last been observed there in 1941. Environmental DNA surveillance was conducted in 2022, and eDNA for the species was detected in both the Clinch and Powell rivers.

The 2021 5-year review of this federally threatened species recommended environmental DNA sampling in future surveys with comparison to DNA extracted from preserved specimens.
