Batrochoglanis Cephalosilurus Cruciglanis Lophiosilurus Microglanis Rhyacoglanis Pseudopimelodus The Pseudopimelodidae are a small family (about 40 species) of catfishes known as the bumblebee catfishes or dwarf marbled catfishes.
[1] However, some evidence has shown this family, along with Pimelodidae, Heptapteridae, and Conorhynchos, may form a monophyletic assemblage, which contradicts the hypothesis that the former family Pimelodidae that included these families is a polyphyletic group.
[3] The Pseudopimelodidae are restricted to fresh water in South America,[1] from the Atrato River in Colombia to Argentina in the Río de la Plata.
[2] These catfishes have wide mouths, small eyes, and short barbels.
[5] However, most species are smaller; species of the genus Microglanis rarely exceed 70 mm(2.8 in) SL and are never over 80 mm (3.1 in) SL.
