Opilio is a genus of harvestmen with 35 known species.
The genus name is derived from Latin opilio "sheep-master" (a kind of slave), used by Plautus, also used by Virgil with the meaning "shepherd". [1]
Opilio contains the following thirty-five species: [2]
The Opiliones are an order of arachnids colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. As of April 2017, 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.
Phalangium is a genus of harvestmen, that occurs mostly in the Old World. The best known species is Phalangium opilio, which is so common in many temperate regions that it is simply called "harvestman".
The Phalangiidae are a family of harvestmen with about 380 known species. The best known is Phalangium opilio. Dicranopalpus ramosus is an invasive species in Europe.
The Sclerosomatidae are a family of harvestmen with about 1,300 known species.
Leiobunum is a genus of the harvestman family Sclerosomatidae with more than a hundred 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.
