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.
Astacoides betsileoensis is a species of crayfish in the family Parastacidae. It is endemic to Madagascar. The populations are threatened by habitat loss due to land conversion as well as harvesting for food from locals and predation from introduced species. As of 2010 there were no specific measures for conservation apart from a minimum size limit of 10 cm for harvesting. In some areas, local rules and taboos help controlling the pressure from harvesting.
Astacoides is a genus of freshwater crayfish endemic to Madagascar. The first specimens were brought to Europe in 1839, and seven species are now recognised, most of which are considered as threatened on the IUCN Red List. They are large and slow-growing, and are threatened by habitat loss, overexploitation by local people and by spread of introduced non-indigenous marbled crayfish. They are only found in a relatively small part of the island, mostly in undisturbed upland areas. They belong to the Gondwana-distributed family Parastacidae, but their nearest relatives live in Australasia, there being no native crayfish in mainland Africa or India.
Astacoides caldwelli is a species of crustacean in family Parastacidae. It is endemic to Madagascar. A. caldwelli is mostly found in rivers draining forested areas at elevations between 600 - 800m. The populations are threatened by habitat loss as well as predation by introduced species and harvesting at a subsistence level from local fishermen.
Astacoides crosnieri is a species of crustacean in family Parastacidae. It is endemic to Madagascar, being widespread in the former Province Fianatantsoa. A. crosnieri inhabits swampy areas at an elevation between 500 – 1000 m above sea level.
