Microthelphusa wymani is a species from the genus Microthelphusa . [1] [2]
Microthelphusa wymani is morphologically similar to M. meansi and M. somanni. [3]
The Bythograeidae are a small family of blind crabs which live around hydrothermal vents. The family contains 16 species in six genera. Their relationships to other crabs are unclear. They are believed to eat bacteria and other vent organisms. Bythograeidae are a monophyletic, sister taxon of the superfamily Xanthoidea which split to inhabit hydrothermal vents around the Eocene.
Pseudothelphusidae is a family of freshwater crabs found chiefly in mountain streams in the Neotropics. They are believed to have originated in the Greater Antilles and then crossed to Central America via a Pliocene land bridge. Some species of this family are troglobitic.
Disparithelphusa pecki is a species of freshwater crab in the family Pseudothelphusidae, and the only species in the genus Disparithelphusa.
Smalleyus is a genus of crabs in the family Pseudothelphusidae, containing the single species Smalleyus tricristatus.
Neoepilobocera gertraudae is a species of cave-dwelling crab from Cuba.
Eudaniela is a genus of crab in the family Pseudothelphusidae.
Guinotia is a monotypic genus of freshwater crabs in the family Pseudothelphusidae, containing only the species Guinotia dentata, commonly known as cyrique. They have few predators. Found in the West Indies, they are easily caught and thus are used locally as a food source.
Hypolobocera is a genus of freshwater crabs in the family Pseudothelphusidae, found in Venezuela, Colombia, Ecuador, and Peru. The major and future threats to these species include human-induced habitat loss/degradation and water pollution.
Microthelphusa is a genus of crabs in the family Pseudothelphusidae, containing the following species:
Strengeriana is a genus of crabs in the family Pseudothelphusidae, containing the following species:
Villalobosius is a genus of crabs in the family Pseudothelphusidae, containing a single species, Villalobosius lopezformenti. It lives in the northern part of the state of Oaxaca, Mexico, on the Isthmus of Tehuantepec, and is adapted to a troglobitic lifestyle.
Around 1,300 species of freshwater crabs are distributed throughout the tropics and subtropics, divided among eight families. They show direct development and maternal care of a small number of offspring, in contrast to marine crabs, which release thousands of planktonic larvae. This limits the dispersal abilities of freshwater crabs, so they tend to be endemic to small areas. As a result, a large proportion are threatened with extinction.
Latreillia elegans is a species of crab belonging to the family Latreilliidae. This family of crabs is identified by their appearance as small, long-legged crabs. The species belongs to the genus Latreillia which has only five identified species: L. elegans, L. metanesa, L. williamsi, L.valida, and L. pennifera. It was previously thought that L. elegans and L. mannengi were two separate species, but it has since been revealed that the two species are synonymous. All the thought to be differences between L. elegans and L. mannengi were in actuality overlaps. The L. mannengi is simply referring to the close relative to the species of L. elegans found in the western Atlantic.
Arquatopotamon jizushanense is a freshwater crab species found in Yunnan, China, and the only species of the genus Arquatopotamon. Its carapace is normally darkish brown and the walking legs and chelipeds more reddish brown.
Nanhaipotamon is a genus of freshwater crabs, in the subfamily Potamiscinae, found in southern China and Taiwan. As of 2018, 18 species have been described. The genus is named after the South China Sea, for it occurs mostly in coastal areas. The genus was first described by R. Bott in 1968 as Isolapotamon (Nanhaipotamon), i.e., a subgenus of Isolapotamon.
Nanhaipotamon hongkongense is a species of freshwater crab of the genus Nanhaipotamon, known to occur in Hong Kong and adjacent areas in Shenzhen and Dongguan, Mainland China.
Parveen F. Absar is a wildlife biologist from India. In 2017, she was credited with the discovery of a species of freshwater crab called Teretamon absarum, of the genus Teretamon and species speleaum.
Limnopilos naiyanetri, commonly referred to as the Thai micro crab or pill-box crab, is a freshwater hymenosomatid crab endemic to Thailand. Its presence has only been confirmed in the Tha Chin River. The species was described in 1991 and represents the type species of Limnopilos. The Thai micro crab was first introduced to the aquarium hobby in 2008 when it was imported to Germany by the tropical fish importer Aquarium Glaser GmbH, and has slowly grown in popularity with aquarium hobbyists. It remains a relatively rare species on the market and detailed information on the husbandry of this species is scarce.
Limnopilos is a genus of small hymenosomatid crabs endemic to Southeast Asia. The genus was described by Christina Chuang and Peter Ng in 1991, who identified the new species Limnopilos naiyanetri and distinguished it from the closely related genus Hymenicoides. Its true taxonomic classification was debated for several years, but in 2007 the discovery of a new species of crab in this genus solidified the distinction between Limnopilos and Hymenicoides. Many aspects of the genus Limnopilos are still poorly understood. Their ecology and natural history have not been studied in detail, and their reproductive cycle remains mysterious.
Epilobocera wetherbeei is a species of crab from the genus Epilobocera. The species was originally described in 1995.
