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.
Miturgidae is a family of araneomorph spiders that includes nearly 170 species in 29 genera worldwide. First described by Eugène Simon in 1886, it has been substantially revised, including of previous family "Zoridae" as subfamily "Zorinae" and excluding the family "Xenoctenidae". Several genera have also been removed, such as the large genus Cheiracanthium, which was transferred to the Cheiracanthiidae.
Cheiracanthiidae is a family of araneomorph spiders first described by Vladimir Wagner in 1887. The synonym Eutichuridae was used for a long time, but Cheiracanthiidae has priority. The largest genus currently recognized as belonging to this family is Cheiracanthium, which has previously been placed in both the Clubionidae and the Miturgidae.
