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.<ref>{{cite journal| last1=Salgado| first1=A.| last2=Ruiz| first2=G.
