Anadoras weddellii is a species of thorny catfish that is found in Argentina, Brazil, Bolivia and Paraguay. This species grows to a length of SL. The IUCN Red List considers Anadoras regani a junior synonym of Anadoras weddellii, but FishBase and the Catalog of Fishes regard it as valid. The fish is named in honor of British physician-botanist Hugh Algernon Weddell (1819–1877), who presented the type specimen in the form of a dried skin and a drawing of the fish.
