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.
Cordylancistrus is a genus of suckermouth armored catfish native to South America. It is much the same as Chaetostoma. The few differences are a wider head, longer cheek odontodes, and plates on the snout. Cordylancistrus can be found in rivers and streams high in the Andes, from Venezuela to Colombia.
Rineloricaria is a genus of freshwater tropical catfish belonging to the family Loricariidae. They are commonly called whiptail catfish because of the long filament that grows out of the tip of the caudal fin that is characteristic of the genus. With the exception of R. altipinnis from Panama, they are native to the rivers of northern and central South America. Some species are regularly seen in the aquarium trade.
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.
Farlowella is a genus of fish in the family Loricariidae native to South America. This genus is broadly distributed in Amazon, Orinoco, Paraná and coastal rivers of the Guyana Shield. It is absent from the Pacific slope of the Andes and from the coastal rivers of the Brazilian Shield. Many of these species are kept in aquariums. This genus has a unique body shape that resembles a thin stick of wood. The body is slender and elongate, often with a pronounced rostrum and a brownish color with two lateral dark stripes beginning at the tip of the rostrum, passing over the eyes and ending at the tail, which are periodically interrupted on the caudal peduncle.
Loricariinae is a subfamily of the family Loricariidae of catfish. This subfamily is divided into two tribes and about 30 genera. They are mainly native to freshwater habitats in South America, but there are also several species in Panama and a single (Fonchiiichthys) in Costa Rica.
Pterosturisoma microps is the only species of the monotypic genus Pterosturisoma, a genus of the family Loricariidae of catfish.

Reganella depressa is the only species of the monotypic genus Reganella, a genus of the family Loricariidae of catfish. R.depressa is a poorly known species and uncommon in collections. Its phylogenetic position remains uncertain.
Rhadinoloricaria macromystax is a species of catfish in the family Loricariidae and the genus Rhadinoloricaria. The genus was monotypic until 2020, when a new species, R. stewarti, was described.

Chaetostoma, also known as the bristlemouth catfish, is a genus of suckermouth armored catfishes native to South America with one species, C. fischeri, extending into Panama. Most species inhabit flowing rivers in the lower Andes and its foothills. Some species are kept in unheated aquaria.
Rhadinoloricaria stewarti is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the drainage basin of the Cononaco River, a tributary of the Napo River, in Ecuador. The species was described in 2020 as part of a redescription of the genus Rhadinoloricaria conducted by Francisco Provenzano and Ramiro Barriga-Salazar. FishBase does not yet list this species.
