Ground spiders comprise Gnaphosidae, the seventh largest spider family with nearly 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.
Gallieniellidae is a family of spiders first described by J. Millot in 1947. It was originally thought to be endemic to Madagascar until species were also found in southern Kenya, northeastern Argentina, and Australia. Drassodella was transferred from the family Gnaphosidae in 1990. They are suspected to be specialized in ant-preying.
Prodidominae is a spider subfamily, sometimes called long-spinneret ground spiders. It was formerly regarded as a separate family, Prodidomidae, which was reduced to a subfamily of the Gnaphosidae in 2018.
Lampona is a genus of South Pacific spiders in the family Lamponidae that was first described by Tamerlan Thorell in 1869. At least two species have a whitish tip to the abdomen and are known as "white-tailed spiders". Both hunt other spiders and have been introduced to New Zealand. The name is derived from the Middle English laumpe, meaning "light" or "fire".
Tamopsis is a genus of tree trunk spiders that was first described by B. Baehr & M. Baehr in 1987. Like other members of the family, they may be called two-tailed spiders, referring to two elongated spinnerets.
