EUTICHURIDAE Sac Spiders

Previously in Miturgidae, the genera Cheiracanthium and Calamoneta (among others) were moved into the newly created family Eutichuridae. It had been known for a long time these genera did not sit comfortably in Miturgidae, many placing them in Clubionidae prior to the creation of Eutichuridae as a family. World wide, the spiders are quite common, rather aggressive in competition with other arthropods and often found associated with humans. Cheiracanthium species are known in some parts of Europe and the Americas as Yellow Sac Spiders. They can deliver painful bites developing into a sore which may be slow to heal, easily infected, and suspected by some of being necrotic or "flesh eating" but this suspicion lacks any clear supporting evidence. Calomoneta species, mostly found in rainforests, have enormously long and slender front legs.
