Sac spider explained
The sac spiders of the family Clubionidae are nocturnal, sac-building hunting spiders with a near-worldwide distribution. Their sacs, silken retreats in which they hide during the day, may be made in a variety of places, including between folded leaves or grass blades, under bark and below rocks or other ground litter.
Although formerly a much larger catch-all taxon, in its current definition the family contains less than 700 described species across 18 genera, of which Clubiona is by far most species-rich, with 528 accepted species .[1]
Taxonomy
The Clubionidae have a complex taxonomic history. Historically, the family was a large catch-all taxon for a variety of spiders that shared the following morphological and behavioral similarities: having eight eyes arranged in two rows; having conical anterior spinnerets that touched; and being nocturnal wandering predators that build "sacs" to retreat to during the day.
A large number of genera have been transferred from Clubionidae to other families, and several former subfamilies of the Clubionidae are now treated as separate families.[2] The Zoropsidae, to which genera Anachemmis, Lauricius and Liocranoides were transferred, is much more closely related to the lynx spiders of family Oxyopidae than to the remaining Clubionidae.[3]
According to 2023 cladistic research by Siddharth Kulkarni, Hannah M. Wood and Gustavo Hormiga, the remaining Clubionidae remain polyphyletic as a result of the current placement of genus Elaver.[3]
