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.
