Abstract

A new species of the fresh-water mussel genus Elliptio (Mollusca: Bivalvia: Unionidae) is described from the Cape Fear River of North Carolina. This species and E. icterina (Conrad 1834) from an advanced group characterized by reproductive capabilities significantly greater than their congeners'. Several working hypotheses emerge from discussions of the new species' ecology and ancestry, including the possibility that portions of the Cape Fear and neighboring river systems once formed a haven for unionid speciation isolated by an interglacial sea.
