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. [1]
This family was formerly a subfamily of Pimelodidae. [1] Pseudopimelodidae is a monophyletic group. [2] Previously, the superfamily Pseudopimelodoidea was sister to superfamilies Sisoroidea + Loricarioidea. [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. [4] Their bold markings lead them to be commonly known as bumblebee catfishes or dwarf marbled catfishes. [1] B. acanthochiroides grows to 80.0 cm (31 in) TL. [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. [4]
The Ictaluridae, sometimes called ictalurids, are a family of catfish native to North America, where they are an important food source and sometimes fished for sport. The family includes about 51 species, some commonly known as bullheads, madtoms, channel catfish, and blue catfish.
Loricariidae is the largest family of catfish, with 92 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as "plecos", notably the suckermouth catfish, Hypostomus plecostomus, and are popular as aquarium fish.
Trichomycteridae is a family of catfishes commonly known as pencil catfishes or parasitic catfishes. This family includes the candiru fish, feared by some people for its alleged habit of entering into the urethra of humans. They are one of the few parasitic chordates. Another species is the life monsefuano which was important to the Moche culture and still an important part of Peruvian cuisine.
The Pimelodidae, commonly known as the long-whiskered catfishes, are a family of catfishes.
The Aspredinidae are a small South American family of catfishes also known as the banjo catfishes, with about 43 species.
The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species. They are found worldwide in tropical to warm temperate zones. The family includes about 143 species.
Microglanis is a genus of fish in the family Pseudopimelodidae native to South America. This genus has the widest distribution within its family, with species ranging from the Guianas to Venezuela; western slope of the Andes in Ecuador and Peru to the Río de La Plata basin in Argentina. They occur eastward to the Orinoco and Amazon basins. It is also present in the eastern coastal rivers of Brazil.
Microglanis leptostriatus is a species of catfish belonging to the family Pseudopimelodidae. It appears to be entirely restricted to the middle and upper basin of the São Francisco River in Brazil.
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.
Brachyplatystoma is a genus of catfish from the family Pimelodidae. As the occasionally used common name goliath catfishes indicates, this genus includes some of the largest species of catfish, including the piraíba, B. filamentosum, which reaches up to the region of 3.6 metres (12 ft) in length. Brachyplatystoma are found in the Amazon and Orinoco basins, and other tropical freshwater and brackish habitats in South America. Some species are migratory. These fish are important as food fish and, to some extent, aquarium fish.
Hemiancistrus is a genus of suckermouth armored catfishes. These species are native to South America. The taxonomy of this genus is complex and unclear, and major work has to be done. Many of these fish are popular aquarium fish.
Exallodontus aguanai is a catfish species of the monotypic genus Exallodontus of the family Pimelodidae. This genus and species was described in 1991. This species reaches 20 centimetres (7.9 in) SL. This species is native to the Amazon and Orinoco River basins of Brazil, Colombia, Peru and Venezuela. Exallodontus 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, Duopalatinus, Cheirocerus, Iheringichthys, Bergiaria, BagropsisParapimelodus, Platysilurus, Platystomatichthys, and Propimelodus.
The porthole shovelnose catfish or spotted shovelnose catfish, Hemisorubim platyrhynchos, is the only species in the genus Hemisorubim of the catfish family Pimelodidae.
Cruciglanis is a genus of catfish of the family Pseudopimelodidae. It contains a single recognized species, Cruciglanis pacifici.
Batrochoglanis is a small genus of catfishes of the family Pseudopimelodidae.
Pseudomystus is a genus of catfishes of the family Bagridae.
Neoplecostominae is a subfamily of South American catfishes of the family Loricariidae. Species of this subfamily live in high-mountain and swift-flowing river habitats.
Malacoglanis gelatinosus is a species of catfish of the family Trichomycteridae, and the only species of the genus Malacoglanis. This fish grows to about 2.0 centimetres (.79 in) SL. and is native to the Caquetá River basin of Colombia. Stauroglanis is the sister group to a monophyletic group formed by Malacoglanis and Sarcoglanis.
Ituglanis is a genus of small freshwater fish in the family Trichomycteridae native to South America. Their greatest diversity seems to occur in the Amazon River basin. Most species inhabit leaf litter, with several species living in caves.
Brachyplatystoma rousseauxii, the gilded catfish or dourada, is a species of catfish of the family Pimelodidae that is native to Amazon and Orinoco River basins and major rivers of French Guiana.
