Amphidraus is a genus of South American jumping spiders first described by Eugène Simon in 1900.[2] It was previously considered a synonym of Nebridia,[3] but this was later rejected by Jerzy Prószyński, who claimed that merging the two genera was not supported by previous diagnostic drawings.[4]

Members of this genus most closely resemble those of Marma and the monotypic genus Yacuitella. All three genera have a projection on the embolic disc that is independent from the embolus and a conductor on the distal retro-ventral region of the cymbium, though it is membranous in Amphidraus and Yacuitella and sclerotized in Marma. Spiders of Amphidraus can be distinguished from these other two by the presence of both a proximal tegular lobe and a cylindrical embolic filament that emerges from the distal region of the embolus shaft.[5]
