This family is monophyletic and contains the subfamilies Doradinae, Astrodoradinae and Wertheimerinae.Birindelli, J.L.O. (2014): Phylogenetic relationships of the South American Doradoidea (Ostariophysi: Siluriformes). ''Neotropical Ichthyology 12(3): 451-564''. The Astrodoradinae contain the genera '' Amblydoras'', '' Anadoras'', ''Astrodoras'', ''Hypodoras'', ''Merodoras'', '' Physopyxis'', and '' Scorpiodoras''. Distribution Doradids occur in most South American basins, though they are absent from the Pacific Coast drainages and from coastal drainages south of the Río de la Plata.
