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.
Potamon is a genus of freshwater or semiterrestrial crabs mainly found from Southern Europe through the Middle East, and as far east as north-western India. The only exception is the North African P. algeriense, which also is the only potamid of mainland Africa. Twenty species are currently recognised. These crabs are omnivores that have a broad ecological tolerance. The adult Potaman reach up to 50 mm in size during their 10-12 year life span.
Trichodactylidae is a family of crabs, in its own superfamily, Trichodactyloidea. They are all freshwater animals from Central and South America, including some offshore islands, such as Ilhabela, São Paulo. Only one of the 50 species is known from the fossil record, Sylviocarcinus piriformis from the Miocene of Colombia. The family contains 15 genera in two subfamilies:
Neostrengeria is a genus of crabs in the family Pseudothelphusidae, containing the following species:
Potamocarcinus is a genus of crabs in the family Pseudothelphusidae.
Ptychophallus is a genus of crabs in the family Pseudothelphusidae.
Pseudothelphusa is a genus of crabs in the family Pseudothelphusidae, containing the following species:
Fredius is a genus of crabs in the family Pseudothelphusidae, containing the following species:
Epilobocera is a genus of crabs in the family Epiloboceridae. It is the only genus in its family; this taxonomic arrangement follows the revision of the family Pseudothelphusidae by Álvarez and colleagues.
Chaceus is a genus of crabs in the family Pseudothelphusidae, containing the following species:
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:
Moritschus is a genus of crabs in the family Pseudothelphusidae, containing the following species:
Phallangothelphusa is a genus of crabs in the family Pseudothelphusidae. It contains five described species:
Phrygiopilus is a genus of crabs in the family Pseudothelphusidae, containing the following species:
Spirothelphusa 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:
