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.
