The Nicodamidae are a spider family with 29 species in nine genera.

They are small to medium-sized spiders found in small sheet webs close to the ground in eucalypt forests. In most cases the cephalothorax and legs are uniformly red and the abdomen black, for which these species are sometimes called the red and black spider.

Distribution

The species of this family are only present in New Zealand and the Australian region.
