Indiana Biological Survey

Division of Crustaceans

The crustacean collection concentrates on crayfish (Decapoda) and includes 50,000 specimens, with most being from over 3,500 sites in Indiana. The collection also includes specimens from Alabama, Tennessee, Kentucky, South Carolina, and Ohio. Recently published is a checklist of crayfish and freshwater shrimp of Indiana (Simon, 2001). The crustacean collection has benefited from donations of materials from Indiana State University, Indiana Department of Environmental Management, Indiana Department of Natural Resources, U.S. Fish and Wildlife Service, U.S. Environmental Protection Agency, and the Bureau of Water Quality from the City of Muncie. The oldest specimens in the collection are from the 1970 surveys of the White River by the Bureau of Water Quality. The crustacean collection also includes larval crayfish and fossil materials. The Division possesses the paratypes for Cambarus (Tubericambarus) polychromatus and Cambarus (Lacunicambarus) erythrodactylus.
