Platysilurus is a genus of long-whiskered catfishes native to South America.


Platysilurus 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, Duopalatinus, Cheirocerus, Iheringichthys, Bergiaria, Bagropsis, Parapimelodus, Platystomatichthys, and Propimelodus.[1]


There are currently three recognized species in this genus: [2]


P. malarmo is distributed in the Lake Maracaibo basin. P. mucosus inhabits the Amazon and Orinoco River basins. P. olallae is found in Ecuador.[3]


P. malarmo reaches 70 centimetres (28 in) SL.[4] P. mucosus grows to a length of at least 20 cm (7.9 in) SL.[5]
