The northern riffleshell, is a subspecies of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This subspecies is endangered. This species was formerly found widely in the Ohio River basin, but now the population is fragmented into only three viable groups. This species exhibits variable shell characteristics across its geographic range. It is unclear whether this is best understood as ecophenotypic variation, various subspecies, or a complex of closely related but genetically isolated species. Due to the extinction of three of the four subspecies often included, resolution of this question will be difficult. The most modern approach is to treat E. torulosa as a species with three subspecies, and separate out the closely related Epioblasma cincinnatiensis as a full species.
