Desidae is a family of spiders, some of which are known as intertidal spiders. The family is named for the genus Desis, members of which inhabit the intertidal zone. The family has been reevaluated in recent years and now includes inland genera and species as well, such as Badumna and Phryganoporus. In 2017, the family Amphinectidae was merged into Desidae and the family Toxopidae was separated from it. Those intertidal spiders that are truly marine commonly live in barnacle shells, which they seal up with silk; this allows them to maintain an air bubble during high tide. They emerge at night to feed on various small arthropods that live in the intertidal zone.
Stiphidiidae, also called sheetweb spiders, is a family of araneomorph spiders first described in 1917. Most species are medium size and speckled brown with long legs. All members of this family occur in New Zealand and Australia except for Asmea. They build a horizontal sheet-like web under rocks, hence the name "sheetweb spiders".
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.
Trite auricoma, commonly known as the golden-brown jumping spider, is a species of jumping spider endemic to New Zealand.
Desis marina, the intertidal spider, is a spider species found in New Zealand, New Caledonia, and the Chatham Islands.
Gasparia is a genus of South Pacific araneomorph spiders in the family Toxopidae, and was first described by Brian J. Marples in 1956. Originally placed with the intertidal spiders, it was moved to the Toxopidae in 2017.
Gohia is a genus of South Pacific araneomorph spiders in the family Toxopidae, and was first described by R. de Dalmas in 1917.
Goyenia is a genus of South Pacific intertidal spiders that was first described by Raymond Robert Forster in 1970.
Hapona is a genus of South Pacific araneomorph spiders in the family Toxopidae, and was first described by Raymond Robert Forster in 1970. Originally placed with the intertidal spiders, it was moved to the Toxopidae in 2017.
Helsonia is a monotypic genus of South Pacific intertidal spiders containing the single species, Helsonia plata. It was first described by Raymond Robert Forster in 1970, and has only been found in New Zealand.
Mangareia is a genus of South Pacific intertidal spiders that was first described by Raymond Robert Forster in 1970. As of May 2019 it contains only two species, both found in New Zealand: M. maculata and M. motu.
Notomatachia is a genus of South Pacific intertidal spiders that was first described by Raymond Robert Forster in 1970. As of May 2019 it contains only three species, all found in New Zealand:
Panoa is a genus of Polynesian intertidal spiders. It was first described by Raymond Robert Forster in 1970, and it has only been found in New Zealand.
Paramatachia is a genus of Australian intertidal spiders that was first described by R. de Dalmas in 1918.
Rapua is a monotypic genus of South Pacific intertidal spiders containing the single species, Rapua australis. It was first described by Raymond Robert Forster in 1970, and has only been found in New Zealand.
Tuakana is a genus of South Pacific intertidal spiders that was first described by Raymond Robert Forster in 1970. As of May 2019 it contains only two species, both found in New Zealand: T. mirada and T. wiltoni.
Hypodrassodes is a genus of South Pacific ground spiders that was first described by R. de Dalmas in 1919.
Toxopidae is a small family of araneomorph spiders, first described in 1940. For many years it was sunk into Desidae as a subfamily, although doubts were expressed as to whether this was correct. A large-scale molecular phylogenetic study in 2016 led to the family being revived.
Arangina cornigera is a species of Dictynidae spider that is endemic to New Zealand.
