Huttoniidae is a family of ecribellate[2] araneomorph spiders containing a single genus, Huttonia, itself containing a single described species, Huttonia palpimanoides. It is known only from New Zealand.[1]

Very few specimens of the genus were known until it was discovered that they primarily inhabited dead fronds of rainforest ferns.[3]

Taxonomy

It was first described by Octavius Pickard-Cambridge in 1880.[4][1] Originally placed with the ant spiders, it was moved to a family of its own, Huttoniidae, in 1984, in the superfamily Palpimanoidea.[5]

Fossils of this family have been found in Cretaceous (Campanian) amber from Alberta and Manitoba, Canada . This extended the known geological age of the Huttoniidae back about 80 million years, supporting the theory of H. palpimanoides being an ousted relict species.[6] They are probably most closely related to the now extinct family, Spatiatoridae.

Although only one species is described, about twenty more undescribed species are thought to exist.[7]
