Gradungulidae
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.
Various species within Grandungulidae build an extensive web consisting of an upper retreat tangle with connecting threads to scaffolding, which supports the ladder-like catching platform, which in turn is glued to the ground. Progradungula is a large spider with very long legs; it resembles Hickmania of Austrochilidae.
