Neopalaemon is a genus of shrimps belonging to the family Palaemonidae. [1]
The species of this genus are found in Central America. [1]
Species: [1]
Cambarus is a large and diverse genus of crayfish from the United States and Canada. The adults range in size from about 5 cm (2.0 in) up to approximately 15 cm (5.9 in).
The Cambaridae are the largest of the four families of freshwater crayfish, with over 400 species. Most of the species in the family are native the United States east of the Great Divide and Mexico, but fewer range north to Canada, and south to Guatemala and Honduras. Three live on the island of Cuba. The species in the genus Cambaroides are the only found outside North America, as they are restricted to eastern Asia.
Potamalpheops is a genus of shrimp in the family Alpheidae. It was originally erected by Powell in 1979 to house species from Africa. Later, Horton H. Hobbs, Jr. realised that the troglobitic shrimp he had described in 1973 from Oaxaca, Mexico as Alpheopsis stygicola, also belonged to the genus, and in 1991, A. J. Bruce described a new species from Australia, further expanding the genus' geographical range. It is now thought to represent a relict taxon from the Tethys Sea.
Palaemonidae is a family of shrimp in the order Decapoda. Many species are carnivores that eat small invertebrates, and can be found in any aquatic habitat except the deep sea. One significant genus is Macrobrachium, which contains commercially fished species. Others inhabit coral reefs, where they associate with certain invertebrates, such as sponges, cnidarians, mollusks, and echinoderms, as cleaner shrimps, parasites, or commensals. They generally feed on detritus, though some are carnivores and hunt tiny animals.
Orconectes is a genus of cave dwelling freshwater crayfish, endemic to suitable habitats in the eastern United States. Surface dwelling species, formerly categorised here, were moved to Faxonius in 2017.
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.
Cambarellus is a genus of small freshwater crayfish in the family Cambaridae. The 19 species are found in Mexico and the Gulf States of the United States. Among the Mexican species, C. areolatus, C. patzcuarensis, and C. prolixus are considered seriously threatened by the IUCN, and C. alvarezi is already extinct. C. chihuahuae was also believed to be extinct until rediscovered in 2012. C. alvarezi and four undescribed, extinct Cambarellus species were restricted to desert spring systems in southwestern Nuevo León; each one shared its habitat with a Cyprinodon pupfish.
Distocambarus is a genus of burrowing crayfish native to Georgia and South Carolina in the United States. It contains five species:
Procambarus is a genus of crayfish in the family Cambaridae, all native to North and Central America. It includes a number of troglobitic species, and the marbled crayfish (marmorkrebs), which is parthenogenetic. Originally described as a subgenus for four species, it now contains around 161 species.
Typhlatya is a genus of shrimp in the family Atyidae. These are small, stygobitic shrimp found in the West Mediterranean region, Caribbean region, Ascension Island and the Galápagos, although the individual species often have very small ranges. Species in this genus are found in salt, brackish and fresh waters, mostly in anchialine habitats and none in the open sea.
Troglocambarus is a monotypic genus of troglobitic crayfish, endemic to Florida. Troglocambarus maclanei is found underground in Hernando, Marion, Alachua, Columbia, Gilchrist and Suwanee counties, and is named after Mr. William A. McLane who first collected it. It is commonly called the North Florida Spider Cave crayfish.
Fallicambarus is a genus of crayfish in the family Cambaridae from the United States and Canada. It includes 12 species, of which one is on the IUCN Red List as a vulnerable species (VU) and one as an endangered species (EN). The species of this genus are all restricted to three states or fewer, from Texas and Oklahoma east to Florida.
Atya is a genus of freshwater shrimp of the family Atyidae, ranging through the Antilles and along the Atlantic and Pacific slopes of Central and South America and in western Africa. It contains the following species:
Macrobrachium is a genus of freshwater prawns or shrimps characterised by the extreme enlargement of the second pair of pereiopods, at least in the male.
Barbicambarus is a genus of freshwater crayfish found in Tennessee and Kentucky in the United States. It comprises two species:
Faxonius is a genus of freshwater crayfish in the family Cambaridae. There are more than 90 described species in Faxonius. It includes the rusty crayfish, an invasive species in North America, and three species, F. virilis, F. immunis, and F. limosus, that are invasive to Europe.
Faxonella creaseri is a species of crayfish, a decapod crustacean in the family Cambaridae. It is one of the four species in the genus Faxonella.
Lacunicambarus is a genus of burrowing crayfishes in the family Cambaridae. There are currently 12 described species in Lacunicambarus, all of which are found east of the Continental Divide in North America. The genus was first recognized in 2018 when it was discovered through genetic analyses that the Cambarus subgenera Lacunicambarus and Tubericambarus were not monophyletic on their own, but that when combined they formed a single monophyletic group distinct from Cambarus. A 2022 study used anchored hybrid enrichment to resolve the Lacunicambarus phylogeny, which elucidated interspecific relationships and highlighted remaining undescribed diversity within the genus.
Creaserinus is a genus of Digger Crayfish in the family Cambaridae. There are about 15 described species in Creaserinus, found in North America.
