Pseudopimelodidae
The Pseudopimelodidae are a small family (about 40 species) of catfishes known as the bumblebee catfishes or dwarf marbled catfishes. Some of these fish are popular aquarium fish. Taxonomy This family was formerly a subfamily of Pimelodidae. Pseudopimelodidae is a monophyly, monophyletic group. Previously, the superfamily Pseudopimelodoidea was sister to superfamilies Sisoroidea + Loricarioidea. 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 polyphyly, polyphyletic group. Distribution The Pseudopimelodidae are restricted to fresh water in South America, from the Atrato River in Colombia to Argentina in the Río de la Plata. Description These catfishes have wide mouths, small eyes, and short barbels. Their bold markings lead them to be commonly known as bumblebee catfishes or dwarf mar ...

Catfish Families
Catfish (or catfishes; order (biology), order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are common name, named for their prominent barbel (anatomy), barbels, which resemble a cat's whiskers, though not all catfish have prominent barbels or "whiskers", with some seemingly not having them. Siluriformes as a whole are Fish scale, scale-less, with neither the Armoured catfish, armour-plated nor the naked species having scales. This order of fish are Autapomorphy, defined by features of the skull and swimbladder. Catfish range in size and behavior from the three List of largest fish, largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivorous and scavenging bottom feeders, down to tiny ectoparasitic species known as the Candiru (fish), candirus.

Pimelodidae
The Pimelodidae, commonly known as the long-whiskered catfishes, are a family of catfishes (order Siluriformes). Taxonomy The family Pimelodidae has undergone much revision. Currently, it contains about 30 genera and about 90 recognized and known but unnamed species. Wikipedia lists 109 species in this family. The low-eye catfish (previously family Hypophthalmidae), and thus the genus '' Hypophthalmus'', which contains four species, was reclassified with the pimelodids. This family previously included fish that are now classified under Pseudopimelodidae (previously subfamily Pseudopimelodinae) and Heptapteridae (previously subfamily Rhamdiinae). This family also previously included '' Conorhynchos conirostris'', currently ''incertae sedis''. However, a molecular analysis has shown unequivocal support for monophyly of the individual families and the genus ''Conorhynchos'' into a clade called Pimelodoidea, including Pimelodidae + Pseudopimelodidae and Heptapteridae + ''Conorhynch ...

Heptapteridae
The Heptapteridae, or three-barbeled catfishes, are a family of catfish that originate from the Americas. Most species are restricted to South America, but '' Imparfinis lineatus'', '' Nemuroglanis panamensis'' and ''Pimelodella chagresi'' are native to Panama, and '' Rhamdia'' species occur as far north as Mexico. The name Heptapteridae is derived from Greek, ''hepta'' meaning seven and ''pteron'' meaning fin. The diversity of this family is poorly known, and many species are yet to be described. So far, some 211 species have been described. This family is equivalent to the previously recognized Rhamdiinae, a subfamily of the family Pimelodidae. However, molecular evidence shows this family is a part of the superfamily Pimelodoidea along with the Pimelodidae, Pseudopimelodidae, and '' Conorhynchos''. The skin of these fish is usually naked (scaleless). They exhibit three pairs of barbels. They have a large adipose fin, and their caudal fin is deeply forked. However, no externa ...
