Migidae, also known as tree trapdoor spiders, is a family of spiders with about 100 species in eleven genera. They are small to large spiders with little to no hair and build burrows with a trapdoor. Some species live in tree fern stems. They have a Gondwanan distribution, found almost exclusively on the Southern Hemisphere, occurring in South America, Africa, Madagascar, Australia, New Zealand and New Caledonia.
Cyatholipidae is a family of spiders first described by Eugène Simon in 1894. Most live in moist, montane forests, though several species, including Scharffia rossi, live in dry savannah regions. They occur in Africa, including Madagascar, New Zealand and Australia, and one species in Jamaica. Most members of this family hang beneath sheet webs. Fossil species occur in the Eocene aged Bitterfield and Baltic Ambers, suggesting a wider geographic distribution in the past.
Mysmenidae is a spider family with about 135 described species in thirteen genera. The family is one of the least well known of the orb-weaving spiders because of their small size and cryptic behaviour. These spiders are found in humid habitats such as among leaf litter and in caves.
