Ground spiders comprise Gnaphosidae, the seventh largest spider family with over 2,000 described species in over 100 genera distributed worldwide. There are 105 species known to central Europe, and common genera include Gnaphosa, Drassodes, Micaria, Cesonia, Zelotes and many others. They are closely related to Clubionidae. At present, no ground spiders are known to be seriously venomous to humans.
Oonopidae, also known as goblin spiders, is a family of spiders consisting of over 1,600 described species in about 113 genera worldwide, with total species diversity estimated at 2000 to 2500 species. The type genus of the family is OonopsKeyserling, 1835.
Prodidomidae is a family of spider, sometimes called long-spinneret ground spiders. It was formerly regarded as a subfamily of Gnaphosidae, but was raised to a family in 2022.
Lygromma anops is one of only three known eyeless spiders in the superfamily Gnaphosoidea, and one of only two known troglobites. It is found in lava caves on Isla Santa Cruz, Galápagos.
Mysmenopsis is a kleptoparasitic genus of tiny tropical and subtropical American spiders in the family Mysmenidae. Most live in the funnelwebs of spiders in the family Dipluridae. M. archeri lives on webs of a species in the family Pholcidae, M. capac and M. cienaga have been observed living in Cyrtophora (Araneidae) webs. One reason why diplurid webs are preferred seems to be that they are persistent in time and space, sometimes spanning several years.
