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]
The Opiliones are an order of arachnids, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. As of July 2024, over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014.
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 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.
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.
Biantidae is a family of the harvestman infraorder Grassatores with about 130 described species.
Podoctidae is a family of the harvestman infraorder Grassatores with about 130 described species.
Gagrella is a large genus of harvestmen in the family Sclerosomatidae from Asia.
Paratamboicus was a genus of harvestmen in the family Sclerosomatidae from the Americas, described by Mello-Leitão 1940 with the type-species by original designation being Paratamboicus bicornutus Mello-Leitão, 1940. It was much later considered as Junior subjective synonym of Holcobunus Roewer 1910 by Tourinho & Kury (2001).
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.
Sorensenellinae is a subfamily of harvestmen in the family Triaenonychidae created by Ray Forster. It includes genera from New Zealand and South Africa, but later phylogenetic studies do not support the inclusion of the South African taxa. Egg guarding is reported in both New Zealand genera and appears to be an example of paternal care.
Sorensenella is a genus in the harvestman subfamily Sorensenellinae in the family Triaenonychidae. It is endemic to New Zealand and currently includes three species and several subspecies. Members of this genus have large pedipalps armed with strong spines. The pedipalps are larger in males.
