Gradungulidae, also known as large-clawed spiders, is a spider family endemic to Australia and New Zealand. They are medium to large-sized haplogyne spiders with three claws and two pairs of book-lungs similar to Mygalomorphae. Some species build extensive webs with an upper retreat tangle and connecting threads to scaffolding. This supports the ladder-like catching platform that is glued to the ground. Progradungula, a large spider with long legs like Hickmania, and Macrogradungula are the only cribellate genera of the family.
Progradungula is a genus of Australian large-clawed spiders that was first described by Raymond Robert Forster and Michael R. Gray in 1979. As of May 2024 it contains only three species: P. barringtonensis, P. carraiensis and P. otwayensis.
