harvestman
n.
one who harvests, one who works in the fields at harvest-time; daddy-longlegs, species of spider with a small body and very long legs
Opiliones
Harvestmen (also known as
daddy long-legs) are eight-legged
invertebrate animals belonging to the order Opiliones (formerly Phalangida) in the class
Arachnida, in the subphylum
Chelicerata of the phylum
Arthropoda.
As of 2006, over 6,400 species of harvestmen have been discovered worldwide, although the real number of extant species may exceed 10,000 species. The order Opiliones can be divided in four suborders:
Cyphophthalmi (Simon, 1879),
Eupnoi (Hansen & Sørensen, 1904),
Dyspnoi (Hansen & Sørensen, 1904) and
Laniatores (Thorell, 1876). Well-preserved fossils have been found in the 400-million year old
Rhynie cherts of Scotland, which look surprisingly modern, indicating that the basic structure of the harvestmen has not changed much since then. Phylogenetic position is disputed: their closest relatives may be the mites (
Acari) or the
Novogenuata.
