A new crayfish, Orconectes burri, is described from the Blood River drainage of western Kentucky and Tennessee. The species occurs in small to medium-sized streams with substrates of gravel and sand. Form I males of O. burri differ from all other members of the genus Orconectes in possessing a first pleopod with terminal elements that comprise 22 to 29% of the total length of the pleopod, and a central projection with a tip that terminates at an 90° angle to the main shaft of the pleopod, which is either directly above or slightly overhanging the distal end of the mesial process.
