Trechaleidae (tre-kah-LEE-ih-dee) is a family of araneomorph spiders first described by Eugène Simon in 1890. It includes about 140 described species in 18 genera, mostly in the New World tropics.
Other names for the family are longlegged water spiders and fishing spiders (although members of the genus Dolomedes are also commonly called fishing spiders). The family Trechaleidae is closely related to Pisauridae (nursery web spiders) and Lycosidae (wolf spiders), and the three families are sometimes referred to as the lycosid group.
Distribution All members of this family live in Central and South America except for Shinobius orientalis, which is endemic to Japan.
