Porrhothele is a mygalomorph spider genus with five described species, all endemic to New Zealand. Before 1980, this genus was considered to belong to the family Dipluridae; later it was moved to Hexathelidae. In 2018, it was placed in its own family, Porrhothelidae.
The genus and family are differentiated from other mygalomorph spiders by the small posterior sigillae and a single row of teeth on the forward-facing margin of the chelicerae. Males have a large number of strong spines on the forward-facing margin of their tibiae.
The genus Porrhothele was erected by Eugène Simon in 1892 for the species Porrhothele antipodiana, which Simon transferred from Mygale – a genus no longer in use, but then used for many mygalomorph spiders. Simon placed the genus in the subfamily Diplurinae, which later became the family Dipluridae. In 1980, Raven transferred the genus to the family Hexathelidae; in 1981, it was transferred to its own family, Porrhothelidae, as a result of a molecular phylogenetic study. The following cladogram shows the possible relationship of Porrhothele to related taxa.
