Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body.
Titanoecidae is a family of araneomorph spiders first described by Pekka T. Lehtinen in 1967. It is fairly widespread in the New World and Eurasia with five genera and more than 50 species worldwide. These are mostly dark-colored builders of "woolly" (cribellate) silk webs. Several species are found at relatively high altitudes in mountain ranges and may be very common in such habitats.
Velvet spiders (Eresidae) are a small group of spiders almost entirely limited to the Old World, with exception of a few species known from Brazil. The characteristics of this family of spiders are that they are entelegyne, eight-eyed araneomorph spiders that build unkempt webs. They are cribellate. Some species are nearly eusocial, lacking only a specialized caste system and a queen. They cooperate in brood rearing, unlike most other spiders except for some African agelenid spiders in the genus Agelena and a few others.
Dictynidae is a family of cribellate, hackled band-producing spiders first described by Octavius Pickard-Cambridge in 1871. Most build irregular webs on or near the ground, creating a tangle of silken fibers among several branches or stems of one plant.
