Long-legged sac spider:
Wikispecies has information related to: Miturgidae

The long-legged sac spiders (family Miturgidae) include nearly 400 species in about 30 genera worldwide.

The largest genus currently recognized as belonging to this family is Cheiracanthium, which used to be placed in the family of "true" sac spider, Clubionidae. The placement of the primarily Old World genus Cheiracanthium in the Miturgidae family is still being debated and may change. Only two species are known from the United States, one of which is obviously introduced. The genus is quite diverse in Africa and at least three or four species are known to occur in Egyptian cotton fields alone. The family would be totally obscure if it were not for the fact that members of Cheiracanthium are documented beneficial predators in agricultural fields and are also known to be mildly venomous to humans. The yellow sac spider, Cheiracanthium inclusum, has been studied more than the other species in regard to its role in controlling pest insects in the southeastern United States. Other genera include the more obscure southwestern US and Mexican Syspira, which superficially resembles a wolf spider (Family Lycosidae). The mostly tropical New World genus Teminius is noted for the thick velcro-like scopula on the undersides of the tarsi.



Genera[edit]

The categorization into subfamilies follows Raven (2009)[1] with the exception of the Systariinae and Eutichurinae which were explicitly excluded by Raven (2009)[2] and by Deeleman-Reinhold (2001).

  • Palicanus Thorell, 1897 (Southeast Asia)
  • Strotarchus Simon, 1888 (USA to Mexico, Costa Rica, Brazil, Pakistan)
  • Systaria Simon, 1897 (Southeast Asia)
  • Tamin Deeleman-Reinhold, 2001 (Borneo, Sulawesi)
  • Xantharia Deeleman-Reinhold, 2001 (Borneo, Sumatra)

The spider family Miturgidae (prowling spiders) includes 371 described species (Platnick 2013). A dozen of these species occur in North America north of Mexico; of these, Cheiracanthium is widepread, Strotarchus piscatorius occurs along the east coast, and the other species are southern (Ubick and Richman 2005).

Miturgids are wandering hunters found in forests, scrub, and rocky deserts. Most are ground dwellers and are found under rocks and plant detritus. Some species may fuel their active lifestyles by supplementing their diets with nectar (Taylor and Pfannenstiel 2008). The life cycle of one of the best know miturgids, Cheiracanthium inclusum, was studied by Peck and Whitcomb (1970). This species can be common in some agricultural crops (where it may be beneficial to farmers by consuming caterpillars and other pest insects). It is also common in houses, where it constructs white sac-like retreats, which may vary in form depending on whether they are to be used for resting, molting, mating, breeding, or hibernating. Despite some claims to the contrary, Cheiracanthium bites are apparently no worse than a bee or wasp sting (Fasan et al. 2008; Vetter and Isbister 2008), although in at least some cases symptoms may be quite unpleasant (e.g., Papini 2012).

Many of the species currently placed in the family Miturgidae were formerly included within Clubionidae (a placement some recent authors have also endorsed) and share with clubionids conical spinnerets, claw tufts, and the construction of silk retreats. Like spiders in many other families, a miturgid's eight eyes are arranged in two rows of four. The taxonomic history of this group was reviewed by Ubick and Richman (2005).
