Linyphiidae is a family of very small spiders comprising 4667 described species in 618 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly known; new genera and species are still being discovered throughout the world. The newest such genus is Yuelushannus from China, formally described in May 2020. Because of the difficulty in identifying such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Cambridgea is a spider genus in the family Desidae and some of the first endemic spiders described from New Zealand. They are known for constructing large horizontal sheet webs measuring up to a square metre in larger species. Cambridgea were originally assigned to the Agelenidae by Dalmas in 1917 but were reassigned to the Stiphidiidae in 1973. Most recently, both Cambridgea and sister genus Nanocambridgea were reassigned to the Desidae, subfamily Porteriinae on the basis of molecular evidence.
Promynoglenes is a genus of Polynesian sheet weavers that was first described by A. D. Blest in 1979.
