Chickamanga Crayfish
Keith A. Crandall, James W. Fetzner, Jr., and Horton H. Hobbs, Jr.Types
Syntypes, Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts 175 (3 male II, 1 female), National Museum of Natural History, Smithsonian Institution, Washington D.C. 4957 (female). Hagen (1870:74) indecated that among the 6 specimens available there were "Male Form I, and II. Fem." The first form male is no longer among the types and was missing from them when examined in the early 1940s.Type Locality
"Tennessee River, (near the borders of ?) Georgia" (Hagen, 1870:74). The emendation offered by Ortmann (1931:97) must be rejected because Cambarus (P.) extraneus does not occur in the Coosa (Etowah) Basin. Ortmann confused C. (P.) coosae with Hagen's species.Range
Known only from the South Chickamauga Creek basin (Tennessee River drainage) in Catoosa, Walker, and Whitfield counties, Georgia, and in the same basin in Hamilton County, Tennessee (Bouchard, 1972b:58).References
