Sabaconidae
''Sabacon'' is a genus of the monotypic harvestman family Sabaconidae, with 59 species (as of 2023). Description Species of the genus ''Sabacon'' have usually thickened pedipalps with stiff, fine hairs, which is unique among harvestmen. Although the small eye tubercle is usually not ornamented, there is a spine on one Nepalese species. Males have long, thin legs, females are stouter. While the Asian and North American species are easy to differentiate from one another by male genital traits. The various European species are very similar to each other, and can be closely related to ''Sabacon cavicolens'' from the eastern United States. Another American species '' Sabacon mitchelli'', which, like the larger ''S. cavicolens'' also occurs in the eastern United States, notably lacks cheliceral glands in the male. Species from the western United States seem closely related to Asian forms. '' Sabacon astoriensis'', initially collected from dried seaweed and debris in beach dunes from ...

Sabacon Cavicolens
''Sabacon cavicolens'' is a species of harvestman. Description Males are a bit longer than 2 mm, females 5 mm. Distribution It was originally described from Bat Cave, Carter County, Kentucky and New Hampshire, and a year later found under rotten logs in a deep gorge at Ithaca, New York.Banks, 1894 ''S. cavicolens'' is distributed over the eastern part of North America, south in the mountains of North Carolina. It is very closely related to ''Sabacon paradoxum, S. paradoxum'' and other European species, but quite different from the other ''Sabacon'' species of the eastern US, the smaller ''Sabacon mitchelli, S. mitchelli''. Shear, 1975 Habitat Most specimens will be found under wet rotting logs of conifer forests, or clinging to the underside of stones. They seem not to walk about during the day, and generally move rather sluggishly. Adult specimens are found at the earliest in mid-autumn, and even later at higher elevations. As they depend on high humidity, it is diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harvestman
The Opiliones (formerly Phalangida) are an order of arachnids, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs (see below). , 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 camel spiders (Solifugae) or a larger clade comprising horseshoe crabs, Ricinulei, ...
