Dolomedidae is a family of spiders comprising seven genera formerly part of the family Pisauridae. It includes the genus Dolomedes, known commonly as raft spiders, and its close relatives.
Taxonomy
The family was first circumscribed by Eugène Simon in 1876, but was later made synonymous with Pisauridae and Bradystichidae. It was restored to family level and redefined in 2025 based on a phylogenetic study of Pisauridae that found the family to be paraphyletic.[2] Morphologically, they differ from pisaurids in possessing a subterminal lateral apophysis below the fulcrum in males, and in females by possessing small, rounded accessory bulbs.
