Escadabiidae is a small neotropical family of the harvestman infraorder Grassatores with six described species. [1]
Escadabiidae are about three millimeters long, with short legs and weak chelicerae. [1]
All known members of this group are endemic to Brazil. The as yet undescribed species in this family expand the range to the coast of Ceará State and caves in the dry central part of Minas Gerais, where the cave-dwelling species could represent an example of relictual distribution. [1]
Escadabiidae are possibly the sister group to Kimulidae. [1]
The name of the type genus Escadabius is combined from the type locality Escada (Pernambuco, Brazil) and Ancient Greek bios "living". [1]
These species belong to Escadabiidae: [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.
Cosmetidae is a family of harvestmen in the suborder Laniatores. With over 700 species, it is one of the largest families in Opiliones. They are endemic of the New World with a Nearctic-Neotropical distribution where a large fraction of the diversity of Opiliones are represented by this single family. Cosmetidae have the northern extent of their range into the USA, where a small number species occur in the southern states. However, the family is especially diverse in Mexico, Central America and northern South America; especially the Andean realms. Their range also extends further south into Argentina and southern Brazil, but they are absent in Chile. Cosmetidae are prevalent in Amazonian region, but only relatively few also occur in Brazilian Atlantic Forest. Several species are also found in the Caribbean.
The Stygnopsidae are a small family of harvestmen, with almost all species found in Mexico.
Agoristenidae are a neotropical harvestman family of the Suborder Laniatores, in the superfamily Gonyleptoidea.
The Manaosbiidae are a family of neotropical harvestmen within the suborder Laniatores.
The Cranaidae are a family of neotropical harvestmen within the suborder Laniatores.
The Icaleptidae are a small family of neotropical harvestmen within the suborder Laniatores. Although only two species have been described, many more are probably to be discovered.
Kimulidae is a small neotropical family of the harvestman infraorder Grassatores with about thirty described species.
Stygnommatidae is a small neotropical family of the harvestman infraorder Grassatores with about thirty described species.
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.
The Fissiphalliidae are a small monotypic neotropical family of harvestmen within the suborder Laniatores, superfamily Zalmoxoidea. It contains only the single genus FissiphalliusMartens, 1988 with seven described species. All species are found in the South America.
The Travuniidae are a small family of harvestman with little more than ten described species, within the suborder Laniatores.
The Cladonychiidae are a small family of harvestman with about 33 described species, within the suborder Laniatores.
Eutimesius is a genus of harvestmen in the family Stygnidae with five described species. All species are found in South America.
Bourguyia is a genus of harvestmen in the family Gonyleptidae with four described species. All species are found in Brazil.
Spaeleoleptes is a genus of harvestmen in the family Escadabiidae with two described species. Both species are found in Brazil as cave endemics.
Poecilaemula is a genus of harvestmen in the family Cosmetidae with eight described species. All species are from Central America or South America. An overview of the taxonomy was provided by Medrano et al. (2024)
Tithaeidae is a family of the harvestman infraorder Grassatores, Epedanoidea with about 40 described species.
