Abstract

A new crayfish, Orconectes margorectus, is described from the lower Ohio River drainage of western Kentucky. The species occurs in small streams with substrates of gravel and cobble. Form I males of O. margorectus differ from all other members of the genus Orconectes Cope in possessing a mandible with a straight incisor region and a first pleopod with straight terminal elements that comprise 24 to 28% of the total length of the pleopod.
