Nicodamidae is a family of araneomorph spiders with twenty-seven species in seven genera.[1] They are small to medium-sized spiders found near the ground of eucalypt forest in small sheet webs. The species of this family are only present in Australia and Papua New Guinea. 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 spiders".
