The Triaenonychidae are a family of harvestmen with about 120 genera and more than 440 described species.
Most Triaenonychidae are from three to five millimeters long, although some species from South Africa can be only 1 millimetre (0.039 in) long. Some species in the subfamily Adaeinae are almost 10 mm (0.39 in) long. Legs are almost always short, measuring 4–12 mm (0.16–0.47 in). The armed pedipalps are large, and much stronger than the legs. [1]
Triaenonychidae are found in North and South America, Japan and Korea, Australia and New Zealand, and Madagascar. [1]
The Triaenonychidae should probably split into at least two families. The genera from the Australian region are considered Triaenonychidae sensu stricto, and may include the strange Synthetonychiidae; the northern species should be grouped with Travuniidae. [1]
The name of the type genus Triaenonyx is combined from Ancient Greek τρίαινα (triaina, "trident, fish spear") and ὄνυξ (onyx, "claw"). [1]
The following genera are included in the family: [2]
Pachylinae is the most diverse subfamily of the harvestman family Gonyleptidae, including around 400 valid species. Major groups of species occur in the Brazilian Atlantic forest, Bolivian/Peruvian highlands, Argentina, and Chilean temperate forest.
The Phalangodidae are a family of harvestmen with about 30 genera and more than 100 described species, distributed in the Holarctic region.
The Sclerosomatidae are a family of harvestmen with about 1,300 known species. One former subfamily has been recently removed to form a new family, Globipedidae.
Leiobunum is a genus of the harvestman family Sclerosomatidae with more than 100 described species. Contrary to popular belief, they are not spiders, although they share a resemblance. They are arachnids, in the order Opiliones, harvestmen. Species in Leiobunum tend to have relatively long legs compared with other harvestmen, and some species are gregarious.
The Nemastomatidae are a family of harvestmen with about 170 described species in 16 recent genera. Several fossil species and genera are known.
Epedanidae is a family of the harvestman infraorder Grassatores with about 200 described species. They are the sister group of the Gonyleptoidea.
Samoidae is a family of the harvestman infraorder Grassatores with about fifty described species.
Podoctidae is a family of the harvestman infraorder Grassatores with about 130 described species.
Prionostemma is a large genus of harvestmen in the family Sclerosomatidae from Mexico, Central America, and South America.
Cristina is a genus of harvestmen in the family Phalangiidae.
Rhampsinitus is a genus of harvestmen in the family Phalangiidae.
Zalmoxis is a genus of harvestmen, within the Zalmoxidae family. They are found in tropical Australia, Borneo, New Guinea, the Philippines and on Pacific islands.
Algidia is a genus in the harvestman family Triaenonychidae. It is endemic to New Zealand and currently includes 7 species and several subspecies.
