The sac spiders of the family Clubionidae[a] 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.[citation needed]

Diversity
18 genera, 665 species

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 as of November 2024.[1]

Taxonomy

edit

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.[citation needed]

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]

Genera

edit

As of November 2024, the Clubionidae consist of over 665 species in 18 genera worldwide,[4] with by far the majority of species in genus Clubiona. The following genera are accepted by the World Spider Catalog:[5]

  • Arabellata Baert, Versteirt & Jocqué, 2010 — New Guinea
  • Bucliona Benoit, 1977 — St. Helena, Kenya, Russian Far East, Korea, Japan, China, Taiwan
  • Clubiona Latreille, 1804 — Africa, North America, Asia, Oceania, South America, Europe, Panama
  • Clubionina Berland, 1947 — St. Paul Is.
  • Elaver O. Pickard-Cambridge, 1898 — North America, Caribbean, Central America, South America, Philippines
  • Femorbiona Yu & Li, 2021 — China, Vietnam
  • Invexillata Versteirt, Baert & Jocqué, 2010 — New Guinea

Notes

  1. ^ the term "sac spider" is also part of the common name of various non-clubionid spiders—such as yellow sac spiders (Cheiracanthiidae) or corinnid sac spiders (Corinnidae)—many of which were formerly included in Clubionidae
