With base on the analysis morphological of 153 characteres and 53 taxa of Aspredinidae are proposed the following results: a) Acanthobunocephalus and Bunocephalus as monophyletic groups and their interrelations resolved b) eight new species of aspredinids, being that five of them already mentioned by Friel and three discoveries during the development of this study; c) reallocation of some species of Bunocephalus (B. amazonicus, B. bifidus, B. iheringii, B. quadriradiatus, B. rugosus) in Acanthobunocephalus; d) Bunocephalus aloikae as a species valid and not as synonym of Bunocephalus amaurus; e) key for species from Acanthobunocephalus and Bunocephalus; f) a new classification for Aspredinidae; and g) the corroboration of the hypothesis that Aspredinidae is sister to the Asian Sisoroidea (Amblycipitidae, Akysidae, Sisoridae, and Erethistidae) as proposed by de Pinna, Britto and Diogo Vandewalle & Chardon, and not to the Doradoidea, as suggested by Friel and Sullivan, Lundberg & Hardman.
