Geocharax
''Geocharax'' is a genus of southern crayfish in the family Parastacidae. There are two described species in ''Geocharax'', both found in Australia. '' Geocharax falcata'' is endemic to the North Grampians in Victoria. This species can be found in the headwaters of the Glenelg River and also throughout the north of the Grampians National Park in southwest Victoria. '' Geocharax tasmanicus'' is endemic to Victoria and Tasmania. Within Tasmania, this species is restricted to the far northwest, occurring between Rocky Cape and Temma on the Tasmanian mainland and also on islands of the Hunter group and King Island. In Victoria, it is restricted to the Otway Region. The IUCN conservation status of ''Geocharax falcata'' is "VU", vulnerable. The species has a limited geographic range, and faces a high risk of endangerment in the medium term. The IUCN status of ''Geocharax tasmanicus'' is "LC", least concern, with no immediate threat to survival. The IUCN status for both species was ass ...

Parastacidae
The Parastacidae are the family of freshwater crayfish found in the Southern Hemisphere. The family is a classic Gondwana-distributed taxon, with extant members in South America, Madagascar, Australia, New Zealand, and New Guinea, and extinct taxa also in Antarctica. Distribution Three genera are found in Chile, ''Virilastacus'', '' Samastacus'' and '' Parastacus'', the last of which also occurs disjunctly in southern Brazil and Uruguay. There are no crayfish native to continental Africa, but seven species on Madagascar, all of the genus '' Astacoides''. Australasia is particularly rich in crayfish. The small genus ''Paranephrops'' is endemic to New Zealand. The genera ''Astacopsis'' is endemic to Tasmania, while a further two are found on either side of the Bass Strait – '' Geocharax'' and ''Engaeus''. The greatest diversity, however, is found on the Australian mainland. Three genera are endemic and have restricted distributions (''Engaewa'', '' Gramastacus'' and ''Tenuib ...
