Gradungulidae is a spider family endemic to Australia and New Zealand with 16 species in seven genera. They are medium to large-sized three-clawed haplogyne spiders with two pairs of book-lungs (like Mygalomorphae). The genus Gradungula lives in forest litter. Progradungula and Macrogradungula are the only cribellate genera of the family.
