|This species was
scientifically described in the year 1840 on the basis of matierial from
the Wabash River in Illinois, it furthermore occurred in the Tennessee
River in Alabama resp. Tennessee.
Subfossil mussel shells, which were found during archaeological excavations in the Davidson County in Tennessee, were also assigned to this species.
The taxonomical position of the Cincinnati Riffleshell is not fully resolved (... and rather confusing). Thus it may well be a distinct species, but it may also be a subspecies of the Blossom Pearly Mussel (Epioblasma torulosa (Rafinesque)), to which various forms with unresolved taxonomical status are assigned as subspecies.
