Pseudopimelodidae is a small family of catfishes. Some of these fish are popular aquarium fish.^[1]

Taxonomy

This family was formerly a subfamily of Pimelodidae.^[1] Pseudopimelodidae is a monophyletic group.^[2] Previously, the superfamily Pseudopimelodoidea is sister to superfamilies Sisoroidea + Loricarioidea.^[1] However, some evidence has shown that 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]

Distribution

Pseudopimelodidae is restricted to freshwater in South America.^[1] These catfish are found from the Atrato River in Colombia to Argentina in the Río de la Plata.^[2]

Description

These catfishes have wide mouths, small eyes, and short barbels.^[4] Their bold markings lead them to be commonly known as bumblebee catfishes or dwarf marbled catfishes.^[1] B. acanthochiroides grows to 80.0 centimetres (31 in) TL.^[5] However, most species are smaller; species of the genus Microglanis rarely exceed 70 millimetres (2.8 in) SL and are never over 80 mm (3.1 in) SL.^[4]
