Range DescriptionThis species occurs in the Mississippian region; Great Lakes: Michigan and Erie; Mobile basin; Gulf Coastal region west to the Rio Grande system of Texas and Mexico (Nuevo Leon and Tamaulipas), and Calcacieu River system of Louisiana (Johnson 1999). Recently this species has been confirmed to be likely extirpated from the main channel of the Detroit River between Lake St. Clair and Lake Erie, Michigan/Ontario; due to zebra mussel invasion (Schloesser et al. 2006). Its extent of occurrence has been estimated to be in excess of 200,000 km2.
