Duopalatinus is a small genus of long-whiskered catfishes native to South America.
Species
There are currently two recognized species in this genus:[1]
- Duopalatinus emarginatus (Valenciennes, 1840)
- Duopalatinus peruanus Eigenmann & Allen, 1942
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]
