The Opiliones are an order of arachnids colloquially known as harvestmen, harvesters, 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.
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.

Clarence James Goodnight was an American zoologist who made contributions to the study of freshwater annelids and harvestmen (Opiliones). He was professor at Brooklyn College, Purdue University, and Western Michigan University. Goodnight was born in Gillespie, Illinois. He earned an associate degree at Blackburn College, then earned his bachelor's, master's, and PhD at the University of Illinois. He produced over 150 publications, including three textbooks. He served as president of the American Microscopical Society (1971), secretary of the American Society of Zoologists, and secretary of the North American Benthological Society. In 1940 he married Marie Louise Ostendorf (1916–1998), with whom he co-authored many publications and described over 300 species, including more than 120 species of Mexican harvestmen.
