Family Corinnidae - Swift Spiders

This page contains pictures and information about Swift Spiders that we found in the Brisbane area, Queensland, Australia.
Family Corinnidae is newly separated from family Clubionidae.
Spiders in this family are small to medium size. Their four pairs of eyes are small and about the same size, from above in two slightly curved rows in a small area.    
Some spiders in this family mimic ants. Their legs are usually long and slender. Most corinnids live in leaf litter or on dry bark of trees. They hunt on open ground and tree trunk. As their common name implies, they run very fast.

Supunna picta, subfamily Castianierinae, leg to leg 30mm
We sometimes found this spider on tree trunk with the Gum Tree Shield Bug nymph. This spider look very similar to the bug nymph. The spider has the black colour body and white markings. Its pair of front legs has the same colour as the nymph's antenna. Most interesting is the spiders walk with three pairs of legs only, and wave its front legs just like antenna. We have more information and pictures in this page.
