Uroballus are about 3 mm long in both sexes. The cephalothorax is very broad, almost square. The abdomen is oval, the first pair of legs thick and short with swollen femora. The other legs are weak. The spinnerets are very long and thin. Among spiders, only Hersiliidae possess longer spinnerets. The function of such long spinnerets remains unknown.
