Cladonychiidae
The Cladonychiidae are a small family of harvestman with about 33 described species, within the suborder Laniatores. Description Members of this family range from less than two to about four millimeters in body length, with robust, spined pedipalps and rather short legs, although the second pair can be as long as two centimeter. Most Cladonychiidae are reddish brown to dark brown, but cave-dwelling species are pale yellow. Not all species have eyes. (2007): Cladonychiidae Hadži, 1935. In: Pinto-da-Rocha ''et al.'' 2007: 179ff Distribution The members of Cladonychiidae are found in Southern Europe and the United States. Fossils ''Proholoscotolemon'' was recently found in Baltic amber. Relationships The genera ''Peltonychia'', ''Holoscotolemon'', '' Erebomaster'', ''Theromaster'', ''Speleonychia'', ''Briggsus'', and ''Isolachus'' from the family Travuniidae and the former family Pentanychidae have been transferred to Cladonychiidae. This left Travuniidae with three genera from ...

Harvestmen
The Opiliones (formerly Phalangida) are an Order (biology), order of arachnids Common name, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant taxon, extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their Phylogenetics, phylogenetic position within the Arachnida is disputed; their closest relatives may be the mites (Acari) or the Novogenuata ( ...
