The sac spiders of the family Clubionidae have a very confusing taxonomic history. Once, this family was a large catch-all taxon for a disparate collection of spiders, similar only in that they had eight eyes arranged in two rows and conical anterior spinnerets that touched, and were wandering predators that built silken retreats, or sacs, usually on plant terminals, between leaves, under bark, or under rocks. These are now recognized to include several families, some of which are more closely related to the three-clawed spiders, like lynx and wolf spiders, than to Clubionidae and related families.
Zorocratidae is a formerly accepted family of spiders. Most of the genera formerly placed in this family have been transferred to the family Udubidae. The type genus, Zorocrates, is now placed in the Zoropsidae.
Liocranidae is a family of araneomorph spiders first described by Eugène Simon in 1897. They are one of several groups called "sac spiders". The holarctic genus Agroeca is the best-known, but it also includes various genera of more obscure spiders that still lack a diagnosis. Two species in the North American genus Neoanagraphis are found in the extremely dry conditions in the Mojave, Sonoran and Chihuahuan deserts. Females live in animal burrows while males wander and are the ones most often caught in pitfall traps.
Zoropsidae, also known as false wolf spiders for their physical similarity to wolf spiders, is a family of cribellate araneomorph spiders first described by Philipp Bertkau in 1882. They can be distinguished from wolf spiders by their two rows of eyes that are more equal in size than those of Lycosidae.
Zoropsis spinimana is a spider species belonging to the family Zoropsidae.
Zorodictyna is a genus of spiders in the family Udubidae native to Madagascar. It has been described as an intermediate genus between Zoropsidae and Dictynidae, though it is now placed in Udubidae. This genus was originally placed in the family Zoropsidae, but it has been reassigned several times since. In 1967, Lehtinen moved it to Miturgidae. In 1999, it was moved back to Zoropsidae, and in 2015, it was moved to Udubidae.
Hortipes is a genus of African corinnid sac spiders first described by J. Bosselaers & J.-C. Ledoux in 1998.

Austrachelas is a genus of African long-jawed ground spiders in the family Gallieniellidae, and was first described by R. F. Lawrence in 1938. Originally placed with the corinnid sac spiders, it was moved to the Gallieniellidae in 2009.
Cteniogaster is a genus of spiders in the family Liocranidae. It was first described in 2013 by Bosselaers & Jocqué. As of 2017, it contains 7 African species.
Lauricius is a genus of North American false wolf spiders that was first described by Eugène Louis Simon in 1888. As of September 2019 it contains two species, found in the United States and Mexico: L. hemicloeinus and L. hooki. Originally placed with the sac spiders, it was transferred to the Zoropsidae in 1967.
Hoedillus is a genus of spiders in the family Zoropsidae. It was first described in 1898 by Simon. As of 2017, it contains only one species, Hoedillus sexpunctatus, found in Guatemala and Nicaragua.
Cauquenia is a genus of spiders in the family Zoropsidae. It was first described in 2013 by Piacentini, Ramírez & Silva. As of 2017, it contains only one species, Cauquenia maule, found in Chile.
Griswoldia is a genus of southern African false wolf spiders. It was first described by A. S. Dippenaar-Schoeman and Rudy Jocqué in 1997, and it has only been found in South Africa.
Itatiaya is a genus of spiders in the family Zoropsidae. It was first described in 1915 by Mello-Leitão. As of 2017, it contains 8 species, all found in Brazil.
