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.
Sabacon is a genus of the monotypic harvestman family Sabaconidae, with 59 species.
The Sironidae are a family of harvestmen with more than 60 described species.

Crosbycus is a potentially monotypic genus of harvestmen in the family Taracidae, with one species found in North America as of 2023, per the World Catalog of Opiliones.

Trogulus torosus is a species of large harvestman occurring in Bosnia and Herzegovina, Croatia, and Montenegro. It is the largest harvestman in the world by body length, up to 23.2 mm.
Trogulus is a genus of Opiliones in the family Trogulidae. Harvestmen in the genus have large, elongated and flattened bodies and a two-segmented tarsus segment on leg II, which distinguishes them from other genera in the family Trogulidae. The legs tend to be short compared to most harvestmen. External morphology tends to be very uniform across species in the genus, making differentiation of species difficult. Species occur in a range of habitats, but are most common in forests where their primary prey, snails, are abundant. Trogulus contains the largest known harvestman by body length, Trogulus torosus.
