A revision of the Tasmanian freshwater crayfish genus Astacopsis Huxley (Decapoda: Parastacidae)

During a broad study of the biology of the freshwater crayfishes in the Tasmanian genus Astacopsis, two distinct forms of Astacopsis franklinii were recognised. These "forms" were found to differ in terms of their general morphology and distribution. As a result, the taxonomy of Astacopsis has been revised to re-establish the three species originally described by Ellen Clark. Astacopsis franklinii Gray has been divided into two separate species, the eastern Astacopsis franklinti and the western Astacopsis tricornis, while the status of Artacopsis gouldi remains unaltered.
