Amaurobiidae is a family of three-clawed cribellate or ecribellate spiders found in crevices and hollows or under stones where they build retreats, and are often collected in pitfall traps. Unlidded burrows are sometimes quite obvious in crusty, loamy soil. They are difficult to distinguish from related spiders in other families, especially Agelenidae, Desidae and Amphinectidae. Their intra- and interfamilial relationships are contentious. According to the World Spider Catalog, 2023, the family Amaurobiidae includes 286 species in 50 genera.
Cribellum literally means "little sieve", and in biology the term generally applies to anatomical structures in the form of tiny perforated plates.
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.
Nanocambridgea is a monotypic genus of intertidal spiders containing the single species, Nanocambridgea gracilipes. It was first described by Raymond Robert Forster & C. L. Wilton in 1973, and is found on New Zealand. Originally placed with the Stiphidiidae, it was moved to the Desidae after a 2017 genetic study. A male described as N. grandis in 2000 was synonymized with Cambridgea reinga in 2011.
Muritaia suba is a species of araneomorphae spider of the family Amaurobiidae, endemic to New Zealand. Its cephalothorax, legs, and chelicerae are a pale reddish brown, while the abdomen is pale yellow brown and has irregular black shading down the dorsal surface.
Mamoea grandiosa is a species in the spider family Desidae that is endemic to New Zealand and was first described by Ray Forster and Cecil Wilton in 1973. The holotype specimen was collected by Beverley Holloway at Solomon Island, off Stewart Island, during the 1955 Dominion Museum expedition.
