Gradungulidae

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. Hickmania, Progradungula (a large spider with long legs like Hickmania,^[1]), and Macrogradungula are the only cribellate genera of the family.
