The shiny pigtoe has been eliminated from most of its historic range.[1] Populations currently exist in the North Fork of the Holston River, Clinch, Powell and Paint Rock river systems.[5] The shiny pigtoe is tachytichtic, spawning between late May and early June.[5] Known glochidial hosts include the common (Luxilus cornutus), warpaint (Luxilus coccogenis), telescope (Notropis telescopus) and whitetail (Cyprinella galactura) shiners.[5]

This species appears to be most closely related to Fusconaia cuneolus.[6]
