of the harvestman family Sabaconidae with about forty species. Species of this genus 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.Shear 1975 The genus is widespread in the temperate northern hemisphere, even extending into the subarctic, with the most southern records from caves in the southeastern United States and high elevations in

. While the Asian and North American species are easy to differententiate from one another by male genital traits, the few European species are very similar, and seem to be closely related to ''S. cavicolens''. ''S. mitchelli'', which, like the larger ''S. cavicolens'', occurs in the eastern US, is quite different from the latter, with males lacking cheliceral glands. Species from the western US seem most closely related to Asian forms. ''S. astoriensis'' is very similar to ''S. dentipalpe'' and ''S. makinoi''; it was collected from dried seaweed and debris in
