Loricariidae is the largest family of catfish, with over 90 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.
Hypostomus is a genus of catfish in the family Loricariidae. They are native to tropical and subtropical South America. H. plecostomus is the popular freshwater aquarium fish formerly known as Plecostomus plecostomus. The taxonomic structure of the Loricariidae is still being expanded by scientists. Hypostomus is a highly species-rich and widely distributed catfish genus.
Isorineloricaria is a genus of catfish in the family Loricariidae from northwestern South America. They live in rivers and streams, typically with slow to moderately running water, in the Orinoco, Maracaibo, Magdalena and Guayas basins. The largest species in the genus reaches up to 52 cm (20 in) in standard length.
Isbrueckerichthys is a genus of armored catfishes which are endemic to Brazil.
Microcambeva is a genus of catfishes of the family Trichomycteridae.
Harttia kronei is a species of armored catfish of the family endemic to Brazil where it is found in the Ribeira de Iguape River basin. This species grows to a length of 12 centimetres (4.7 in) SL.
Isbrueckerichthys alipionis is a species of armored catfish endemic to Brazil where it occurs in the Ribeira de Iguape River basin. This species grows to a length of 8.15 centimetres (3.21 in) SL.
Isbrueckerichthys duseni is a species of armored catfish endemic to Brazil where it occurs in the Ribeira de Iguape River basin. This species grows to a length of 9.88 centimetres (3.89 in) SL.
The Ribeira de Iguape River, or simply the Ribeira River, is a river of Paraná and São Paulo states in southeastern Brazil. It flows into the Atlantic Ocean near Iguape. The river is home to several endemic species of fish. So far no dams have been built on the river, although four have been proposed. Although it flows through a relatively sparsely populated region with untouched areas of Atlantic Forest, the river has been contaminated with heavy metals from mining beyond the point where it is considered safe to eat the molluscs found in the river and its estuary.
Lampiella gibbosa is a species of armored catfish endemic to Brazil where it is found in the Ribeira de Iguape River basin. This species is the only recognized member of its genus. This species grows to a length of 5.0 centimetres (2.0 in) TL.
Vale do Ribeira is a region in the south of the state of São Paulo and the northeast of the state of Paraná, Brazil. It contains a large part of the Ribeira de Iguape River valley, from which it takes its name, as well as the coastal Iguape-Cananéia-Paranaguá estuary lagoon complex. The region is environmentally rich, with large areas of well-preserved Atlantic Forest, but economically poor.
Hisonotus leucofrenatus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Ribeira de Iguape River basin. The species reaches 6 cm SL.
Ancistrus trinitatis is a dubious species of catfish in the family Loricariidae. It is known only from the Caribbean, where it occurs in freshwater environments on the island of Trinidad in Trinidad and Tobago. This species is of uncertain validity, as Theodore Gill referred to the type material in 1858 as Ancistrus guacharote and it was later described by Albert Günther in 1864 as Chaetostomus trinitatis, but neither description is considered sufficient to determine the validity and identity of the taxon. While the original locality of the type material was listed as Puerto Rico, this was determined to be in error and the material was determined to have actually originated from the Maracaibo Basin of Venezuela. In 1946, Henry Weed Fowler described the species Ancistrus maracasae from Trinidad, and in 2019, Lesley S. De Souza, Donald C. Taphorn, and Jonathan W. Armbruster determined that A. maracasae and A. trinitatis are synonymous, designating the holotype of A. maracasae as the neotype of A. trinitatis, although sources such as FishBase and ITIS list the two species as valid but separate.
Aphanotorulus gomesi is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Jaguaribe River basin. The species reaches 14.3 cm SL. It is thought to be a facultative air-breather.
Hypostomus agna is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Ribeira de Iguape River basin. It was formally described as a new species in 1907 by Brazilian ichthyologist Alípio de Miranda-Ribeiro, as a species of Plecostomus.
Hypostomus arecuta is a species of catfish in the family Loricariidae. It is a freshwater fish native to South America, where it occurs in the Paraná River in Argentina.
Hypostomus interruptus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Ribeira de Iguape River basin in Brazil, with the type locality reportedly being the Juquiá River. The species reaches 12 cm in standard length and is believed to be a facultative air-breather.
Hypostomus leucophaeus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Itapicuru River basin in the state of Bahia in Brazil. It is typically seen in stretches of rivers up to 50 m (160 ft) wide and 1.8 m (5.9 ft) deep, with clear water, rocky substrates, moderate to fast current, and an altitude of 38 to 449 m above sea level. The species reaches 15.8 cm (6.2 in) in standard length. Its specific epithet, leucophaeus, is derived from Latin and means "ash-colored", in reference to the general coloration and patterning of the species.
Hypostomus pantherinus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Madeira River basin in Brazil. The species reaches at least 4.8 cm in standard length and is believed to be a facultative air-breather. Although originally described by Rudolf Kner in 1854 based on a single specimen from the Guaporé River basin in Brazil, Hypostomus pantherinus was redescribed in 2021 and its range was found to also include Bolivia.
Rineloricaria kronei is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Ribeira de Iguape River basin in Brazil. The species is believed to be a facultative air-breather.
