Duopalatinus is a small genus of catfishes (order Siluriformes) of the family Pimelodidae. It contains two species, D. emarginatus and D. peruanas.[1]

Duopalatinus is classified under the "Calophysus-Pimelodus clade". Within this clade, it is considered a part of the "Pimelodus-group" of Pimelodids, which also includes Pimelodus, Exallodontus,Cheirocerus, Iheringichthys, Bergiaria, Bagropsis, Parapimelodus, Platysilurus, Platystomatichthys, and Propimelodus.[2]

Duopalatinus species are distributed in South America. D. emarginatus inhabits the São Francisco River basin.[3] D. peruanus is found in the Amazon and Orinoco River basins.[4]

Duopalatinus species grow to about 14–15 centimetres (5.5–5.9 in) SL.[3][4]
