CHEIRACANTHIIDAE Sac Spiders

Previously in Miturgidae, the genera Cheiracanthium now split with the addition of Eutittha and Calamoneta (among others) were moved into the newly created family Eutichuridae. An older name, Cheiracanthiidae, name was then found valid to replace Eutichuridae. World wide, the spiders are quite common, rather aggressive in competition with other arthropods and often found associated with humans. Some species are known in 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 supporting evidence. Calomoneta species, mostly found in rainforests, have enormously long and slender front legs.
