The Family Parastacidae is further organized into finer groupings including:
- Genus (14): Astacoides · Astacopsis · Engaeus · Engaewa · Euastacus · Geocharax · Gramastacus · Ombrastacoides · Paranephrops · Parastacus · Samastacus · Spinastacoides · Tenuibranchiurus · Virilastacus
- Species: ZipcodeZoo has pages for 132 species and subspecies in the Family Parastacidae.
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 on the IUCN Red List. They are large and slow-growing, and are threatened by habitat loss and overexploitation by local people. 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. [more]
Engaeus is a genus of freshwater crayfish found in Australia. Fifteen of the 35 species in the genus occur in Tasmania, where they are known as the Tasmanian land crayfish. The behaviour of these crayfish is notable as they live in burrows and construct large "chimneys" at the opening. [more]
Engaewa is a genus of burrowing crayfish belonging to the family Parastacidae. There are five recognised species, all endemic to the high-rainfall zone of south-west Western Australia, from Dunsborough to Albany. They are all small (up to 5 cm), and found only in freshwater swamps and seepages. Three of the five species are listed under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and are listed on the IUCN Red List as "endangered" (EN) or "critically endangered" (CR), while the remaining two are listed as "Least Concern": [more]
Euastacus is a genus of freshwater crayfish known as "spiny crayfish". They are found in the south-east of the Australian mainland, along with another genus of crayfish, Cherax. Both genera are members of the Parastacidae family, a family of freshwater crayfish restricted to the Southern Hemisphere. [more]
At least 3 species and subspecies belong to the Genus Virilastacus.
