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.
Aelurillus is a genus of spiders in the family Salticidae.
Pseudicius is a genus of the jumping spiders first described by Eugène Simon in 1885. The name is combined of Greek pseudo "false" and the salticid genus name Icius. The small genus Wesolowskana should possibly be included in this genus. There is some dispute whether Afraflacilla is a distinct genus or should be included in Pseudicius. Festucula and Marchena are other close relatives, these genera form a monophyletic group.
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.
The Gnaphosoidea or gnaphosoids are a superfamily of araneomorph spiders with seven families. A 2014 study did not find the group to be monophyletic.
Drassodes is a genus of ground spiders that was first described by Niklas Westring in 1851. They are brown, gray, and red spiders that live under rocks or bark in mostly dry habitats, and are generally 3.8 to 11.6 millimetres long, but can reach up to 20 millimetres (0.79 in) in length.
Trachelidae is a family of araneomorph spiders first described by Eugène Simon in 1897 as a subfamily called "Tracheleae". The Trachelidae family, also known as "ground sac spiders", is within the group of spiders known as the RTA clade, which includes mostly wandering spiders that do not use webs. Spiders in the Trachelidae family are characterized as being 3-10mm long and having a red cephalothorax and a yellow/tan abdomen. They are commonly found indoors. It was placed in the family Clubionidae, then later in Corinnidae when the Clubionidae were split up. The first study that suggested Trachelidae should be considered its own family was done by Deeleman-reinhold in 2001 as part of an analysis of RTA Clade spiders. An analysis by Martín J. Ramírez in 2014 suggested that it was not closely related to other members of the Corinnidae, and was better treated as a separate family. It was then placed in the CTC clade of spiders, or the Claw Tuft Clasper clade, which is a group of spiders that have two tarsal claws with tufts of hair.
Micaria is a genus of ground spiders that was first described by Niklas Westring in 1851. They are 1.3 to 6.5 millimetres long.
Medmassa is a genus of corinnid sac spiders first described by Eugène Simon in 1887 under the name "Megaera", later renamed because "Megaera" was already in use as a synonym of the reptile genus Trimeresurus.
Nomisia is a genus of ground spiders that was first described by R. de Dalmas in 1921.
Poecilochroa is a genus of ground spiders that was first described by Niklas Westring in 1874.
Synaphosus is a genus of ground spiders that was first described by Norman I. Platnick & M. U. Shadab in 1980.
Talanites is a genus of ground spiders that was first described by Eugène Simon in 1893.
Trachyzelotes is a genus of ground spiders that was first described by H. Lohmander in 1944 as a subgenus of Zelotes, and was raised to genus status in 1967. It has a body length of 3 to 13 millimetres.
Alioranus is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1926.
Nomindra is a genus of Australian ground spiders that was first described by Norman I. Platnick & Barbara Baehr in 2006. Originally placed with the long-spinneret ground spiders, it was transferred to the ground spiders in 2018.
Prodidomus is a genus of long-spinneret ground spiders that was first described by Nicholas Marcellus Hentz in 1847.
Wesmaldra is a genus of Australian ground spiders that was first described by Norman I. Platnick & Barbara Baehr in 2006. Originally placed with the long-spinneret ground spiders, it was transferred to the ground spiders in 2018.
Plynnon is a genus of Southeast Asian araneomorph spiders in the family Phrurolithidae, first described by Christa L. Deeleman-Reinhold in 2001. As of April 2019 it contains only three species, all from Indonesia and Borneo.
Marinarozelotes is a genus of ground spiders first described by A. V. Ponomarev and V. Y. Shmatko in 2020. The type species, Marinarozelotes barbatus, was originally described under the name "Melanophora barbata".
