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]
