CLUBIONIDAE Sac spiders

Australian clubionids are a widespread, little-studied family of ground and foliage hunting spiders. They are medium to large, body length 4-30mm, with rectangular cephalothorax, squarish at the rear. They have 8 eyes. The back row of eyes is wider. Fangs can be aligned diagonally. The chelicerae or jaws are porrect, meaning pointing forward. The abdomen is generally elongated and roughtly oval, to slightly triangular. The spinnerets are all about the same length. Legs I, II, and III are directed forward. Leg IV is obviously longer than the others. Most have silken retreats usually at the tips or or between outer leaves of shrubs, often in gardens. They have two claws at the end of the tarsus and dense claw tufts. For a long time the only described Australian genus was Clubiona for which many new species await description. More recently Peroneta has been found in the northern tropics.
