Dyspnoi
Dyspnoi is a suborder of harvestmen, currently comprising 43 extant genera and 356 extant species, although more species are expected to be described in the future. The eight families are currently grouped into three superfamilies: the Acropsopilionoidea, Ischyropsalidioidea, and Troguloidea. Distribution The Dyspnoi are one of the most biogeographically conserved higher groups of harvestmen. With the exception of Acropsopilioidea, none occur in the Southern Hemisphere, and most families are restricted along temperate regions. The only exceptions are some Ortholasmatinae (Nemastomatidae) inhabiting the tropics on high mountains in Mexico (''Ortholasma bolivari'') and northern Thailand ('' Dendrolasma angka'').

Harvestmen
The Opiliones (formerly Phalangida) are an order of arachnids 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 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 phylogenetic position within the Arachnida is disputed; their closest relatives may be the mites (Acari) or the Novogenuata (the Scorpiones, Pseudoscorpiones, and Solifugae). Altho ...

Nipponopsalididae
Nipponopsalididae is a family of harvestmen with three described species in one genus, ''Nipponopsalis'', which is found in East Asia. Name The genus name ''Nipponopsalis'' is a combination of ''Nippon'', meaning Japan, where the genus was first discovered, and the ending of the harvestman genus ''Ischyropsalis'', which comes from the Greek "psalis" (scissors), referring to the long chelicerae. Description They range in body length from 2.3 to 4.1 mm. The carapace is domed, with a large, low ocularium, and rather large eyes. The pedipalps and legs are very long and slender, and the chelicerae are longer than their body and heavily sclerotized. These chelicerae are superficially similar to those found in some Ischyropsalidioids, although this is a case of convergence. The cheliceral fingers exhibit 2 forms of teeth: narrow diaphanous teeth in the middle, and courser teeth distally. The opisthosoma is generally poorly sclerotized, and the ''corona analis'' is incomplete. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sabaconidae
Sabaconidae is a family of harvestmen with 57 described species in one genus, ''Sabacon'', which is found throughout the Northern Hemisphere. Name The name of the type genus is derived from "Sabacon", an Egyptian king. Description This family is very easily recognizable on the basis of the unique pedipalp morphology, which is densely covered in plumose setae, and features a concave depression on the tibia, and a bulbous tarsus, which fits snugly into the tibial depression. Distribution Sabaconidae exhibits a wide, yet highly disjunct, distribution. Species can be found throughout North America, Europe, and Asia, though individual species usually have very restricted distributions. Fossil Record There is one species, ''Sabacon bachofeni'' Roewer, 1939, known from Baltic amber. Relationships Sabaconidae belongs to the superfamily Ischyropsalidoidea. The family originally consisted of just the genus *Sabacon*, though *Taracus* was later added to the family. *Hesperonemastoma* wa ...

Nemastomatidae
The Nemastomatidae are a family of harvestmen with about 170 described species in 16 recent genera. Several fossil species and genera are known. Unlike some related currently recognized families, the Nemastomatidae are monophyletic. (2007): Nemastomatidae. Simon, 1872. In: Pinto-da-Rocha et al. 2007: 148ff Description Members of the Nemastomatidae range in body length from about one to almost six millimeters. Their chelicerae are of normal proportions, but the pedipalps are very elongated and thin in some groups. Leg length is likewise variable. Distribution The subfamily Ortholasmatinae (ten species in two genera) occur on both sides of the Pacific Ocean: in western North America from Mexico to British Columbia and eastern Asia (Japan and northern Thailand. The other subfamily, Nemastomatinae, occur all over Europe up to Iceland and the Caucasus, in the Atlas Mountains of North Africa, from Anatolia to northern Iran, with a few species found outside this region, in Central Asi ...

Dicranolasmatidae
The Dicranolasmatidae are a family of harvestmen with 16 described species in a single genus, ''Dicranolasma''. Description Species of ''Dicranolasma'' range in body length from three to 6.4 mm. Most parts of the body are encrusted with soil particles. The anterior region features a large headlike "hood" with the eyes in center, which consists of two curved processes. The chelicerae and pedipalps are both hidden under the hood in adults and about half as long as the body. The legs are short. Immature forms are quite different from adults. The immature form of ''D. opilionoides'' was even described as a different genus (''Amopaum''). The hood develops only gradually, so in young ''Dicranolasma'' the relatively longer pedipalps are carried outside the hood. (2007): Dicranolasmatidae Simon, 1879.
