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. [1] These catfishes are primarily found in torrential streams in the Andean area. [1] Astroblepus pholeter and A. riberae are troglobites adapted to living in subterranean water systems. [2] These species are typically small, less than 10 cm (4 in). [1] The largest species reaches 30 cm (1 ft). [1] 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. [3] 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. [3]
Some of these fish are able to live in high altitude and climb the faces of waterfalls. [3] Their climbing ability comes from specially developed pelvic fins, as well as their suckermouths. [3] In their Neotropical Andean habitat, dry and wet seasons are quite extreme, and odontodes may help in sensing food, mates and water flow, as well as help cling to surfaces. [3] They feed upon invertebrates, such as caterpillars and annelids. [3]
The Astroblepidae were usually placed within Siluriformes as the sister family of Loricariidae, [4] [5] but a recent study found them to be more closely related to the family Scoloplacidae. [6] [7]
There are currently 80 recognized species in this genus:
Ancistrus is a genus of nocturnal freshwater fish in the family Loricariidae of order Siluriformes, native to freshwater habitats in South America and Panama. Fish of this genus are common in the aquarium trade where they are known as bushynose or bristlenose catfish. In the aquarium hobby they are often referred to as bushynose or bristlenose plecos instead, but this may lead to confusion as "pleco" usually is used for Hypostomus plecostomus and its allies and is often used as a catchall term for any loricariids remotely resembling that species.
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.
Trichomycterus is a genus of fish in the family Trichomycteridae, the largest genus of its family with over 170 species currently described. This genus is native to freshwater habitats in Central and South America. These fish are generally small, usually about 5 to 15 cm (2–6 in) in standard length, although the largest, T. rivulatus, can reach more than twice this size. Species differ from one another primarily in body proportions, fin ray counts and colouration. Despite their relatively small size, some, such as T. punctulatus, support fisheries and are important in the local cuisine.
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.
Henonemus is a genus of pencil catfishes native to South America.
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.
Lebiasina is a genus of fishes found in tropical South America, where they inhabit well-oxygenated upland streams that originate in the Andes of Colombia, Ecuador and Peru, the Guianan Highlands in Brazil, Guyana and Venezuela, and Serra do Cachimbo in Brazil. The individual species tend to have relatively small ranges and the three species of Serra do Cachimbo, all restricted to the Curuá River basin, are considered threatened by Brazil's Ministry of the Environment.
Imparfinis is a genus of three-barbeled catfishes native to South America, with a single species in Central America.
Astroblepus chapmani is a species of catfish of the family Astroblepidae. It can be found in the Magdalena River in Colombia.
Astroblepus eigenmanni is a species of catfish of the family Astroblepidae. It can be found on Ecuador.
Astroblepus grixalvii is a species of catfish of the family Astroblepidae. It can be found in Colombia and Ecuador.
Astroblepus guentheri is a carnivorous species of catfish of the family Astroblepidae. It can be found in rainforest streams in the basin of the Magdalena-Cauca rivers and in some Pacific slope rivers in Colombia. It is an uncommon and not well studied species.
Astroblepus homodon is a species of catfish of the family Astroblepidae. It can be found in Colombia.
Astroblepus mariae is a species of catfish of the family Astroblepidae. It can be found on the Meta River in Colombia and Venezuela.
Astroblepus nicefori is a species of catfish of the family Astroblepidae. It can be found of the Cauca River and the Magdalena River in Colombia.
Astroblepus regani is a species of catfish of the family Astroblepidae. It can be found in Ecuador.
Astroblepus simonsii is a species of catfish of the family Astroblepidae. It can be found in Peru.
Chaetostoma floridablancaensis is a species of catfish in the family Loricariidae. It is native to South America, where it occurs only in Colombia. The species reaches 10.1 cm SL, was described in 2013, and was named for the municipality of Floridablanca in Colombia's Santander Department, the homeland of Carlos A. Ardila Rodríguez, the description's author.
