Short, J. W., 1991. Cherax nucifraga, a new species of freshwater crayfish (Crustacea: Decapoda: Parastacidae) from the Northern Territory, Australia.

A new species of freshwater crayfish, Cherax nucifraga (Arthropoda: Crustacea: Decapoda: Pleocyemata: Astacidea: Parastacidae), from the Northern Territory, Australia, is described and illustrated. The species most closely resembles C. barretti Clark, and has affinities with the "quadricarinatus" species-group, characterised by an uncalcified patch on the propodus of the first chelipeds in large males.
