Trachycorystes is a genus of driftwood catfishes found in tropical South America.
There are currently four described species in this genus: [1]
Hemipsilichthys is a genus of catfishes belonging to the family Loricariidae. These wide-mouthed freshwater catfishes are restricted to southeast Brazil in the Paraíba do Sul, Perequê-Áçu and Taquari river basins. Hemipsilichthys, along with Delturus, form a clade (Delturinae). In these two genera, members have a ridge behind their dorsal fin and an adipose fin membrane. However, in Hemipsilichthys, the dorsal fin membrane and most anterior plate of the adipose fin do not touch, while they do in Delturus.
Astroblepus is a genus of fish in the family Astroblepidae found in South America and Panama. This genus is the only member of its family. These catfishes are primarily found in torrential streams in the Andean area. Astroblepus pholeter and A. riberae are troglobites adapted to living in subterranean water systems. These species are typically small, less than 10 cm (4 in). The largest species reaches 30 cm (1 ft). These fish have suckermouths like those of loricariids. They have two pairs of barbels, maxillary and nasal. The dorsal fin spine lacks a locking mechanism. These fish also have odontodes, tiny teeth on their skin. All species exhibit a conical, pointy type on their fin rays like that found in other loricarioids; other species also exhibit a blunt type that is only found on their skin.
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.
Megalodoras is a small genus of thorny catfishes native to tropical South America.
Sturisoma is a genus of armored catfishes native to Central and South America.
Loricaria is a genus of armored catfish native to South America.
Cathorops is a genus of catfishes in the family Ariidae found in the Atlantic and Pacific Oceans. These species are found in the eastern and western Central and South America in brackish and freshwater habitats. This genus is a strongly supported clade of this family. It consists of a natural group in which the monophyly is well-defined by morphological and molecular evidence and the genus probably includes several unrecognized species from both American coasts.
Pimelodella is a genus of three-barbeled catfishes.
Rhamdia is a genus of three-barbeled catfishes found in Mexico, Central and South America. These catfishes are nocturnal, opportunistic carnivores, found in a wide range of freshwater habitats. This genus includes a number of troglobitic members, encompassing a number of taxa, including R. enfurnada, R. guasarensis, R. laluchensis, R. laticauda, R. macuspanensis, R. quelen, R. reddelli and R. zongolicensis. In a few of these only some of their populations are troglobitic.
Bunocephalus is a genus of banjo catfishes from South America. It is found in Magdalena, Orinoco, Amazon, Paraguay-Paraná, and São Francisco Rivers. It is also the only aspredinid genus found west of the Andes, found in the Atrato, San Juan, and Patía Rivers. This genus is a part of the family Aspredinidae, known as banjo catfishes for their large, flattened heads and slender tails that give the appearance of a banjo. Most species exhibit cryptic coloration, and the same holds true among Bunocephalus species. The skin is completely keratinized and is covered by large, unculiferous tubercles. Bunocephalus species may reach up to 13 centimetres SL.
Pseudoplatystoma fasciatum or barred sorubim or barred catfish is a species of long-whiskered catfish native to the Suriname, Corantijn and Essequibo. The nocturnal predator feeds mainly on other fish and crabs. Females reach a more notable size. They become sexually mature at 56 cm (22 in), males at 45 cm (18 in) and this species reaches a maximum length of 90 cm (35 in) TL. Fecundity seems to be estimated at 8 million eggs per kg, but was recently measured in aquaculture at a lower, and more likely number of 150,000 eggs laid per kg.
Auchenipterus is a genus of driftwood catfishes.
Chasmocranus is a genus of three-barbeled catfishes native to South America.
Pseudobunocephalus is a genus of banjo catfishes.
Brachyglanis is a genus of Three-barbeled catfishes native to South America.
Trachycorystes trachycorystes, the black catfish, is a species of driftwood catfish found in Brazil, Guyana and Venezuela. It is also sold in the aquarium trade. It grows to a length of 35 cm.
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.
Notarius is a genus of fish in the family Ariidae found in the Atlantic and Pacific Ocean.
Pseudauchenipterus is a genus of driftwood catfish that occur in tropical South America.
Dolichancistrus is a genus of suckermouth armored catfishes native to South America.
