Hoplomyzon cardosoi, is a species of fish from the genus Hoplomyzon . [1] The species was originally described by Tiago P. Carvalho, Roberto E. Reis and John P. Friel in 2017 [1] [2]
Hoplomyzon cardosoi is a miniature species of banjo catfish from Lake Maracaibo in Venezuela. They have a length between 1.5 and 1.9 mm [1]
Hoplomyzon cardosoi is endemic to the Maracaibo Basin in the Zulia State in Venezuela [1]
Hoplomyzon cardosoi is named after Alexandre Rodrigues Cardoso [1]
The Aspredinidae are a small South American family of catfishes also known as the banjo catfishes, with about 43 species.
Epactionotus is a genus of armored catfishes native to South America.
The Hypoptopomatinae are a subfamily of catfishes of the family Loricariidae, composed of 17 genera and approximately 80 species. This subfamily represents about one-tenth of all loricariid species.
Hoplomyzon is a genus of banjo catfishes that are native to tropical South America.
Micromyzon is a genus of tiny catfish in the family Aspredinidae native to relatively deep parts of the Amazon and Orinoco basins in South America.
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.
Gymnotocinclus anosteos is a species of armored catfish (Loricariidae) endemic to Brazil, where it is found in the Tocantinzinho River in the Tocantins River basin. This species grows to a length of 4.4 centimetres (1.7 in) SL.
Hoplomyzon atrizona is a species of banjo catfish endemic to the Lake Maracaibo basin in Venezuela. It grows to a length of 2.7 cm.
Hoplosternum magdalenae is a species of catfish of the family Callichthyidae. It is found west of the Andes, in the Lake Maracaibo basin in Venezuela, and in the drainages of Sinu River and Magdalena River in Colombia.
In biogeography, geodispersal is the erosion of barriers to gene flow and biological dispersal. Geodispersal differs from vicariance, which reduces gene flow through the creation of geographic barriers. In geodispersal, the geographical ranges of individual taxa, or of whole biotas, are merged by erosion of a physical barrier to gene flow or dispersal. Multiple related geodispersal and vicariance events can be mutually responsible for differences among populations. As these geographic barriers break down, organisms of the secluded ecosystems can interact, allowing gene flow between previously separated species, creating more biological variation within a region.
Micromyzon orinoco is a species of catfish in the family Aspredinidae.
Hisonotus aky, sometimes known as the green hisonotus, is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in Argentina's Uruguay River basin. It reaches 4 cm SL. It was formerly considered a member of the genus Epactionotus, although it was transferred to Hisonotus in 2009.
Hisonotus brunneus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Jacuí River and Lagoa dos Patos drainage basins in Brazil. The species reaches 4.2 cm SL.
Hisonotus heterogaster is a species of catfish in the family Loricariidae. It is a freshwater fish native to South America, where it occurs in the Jacuí River basin and the Lagoa dos Patos system in Brazil. It reaches 4.3 cm SL.
Hisonotus iota is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Chapecó River, which is a tributary of the Uruguay River. The species reaches 3.3 cm SL.
Hisonotus megaloplax is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the drainage basin of the Passo Fundo River, which is a tributary of the Uruguay River. It reaches 4.7 cm SL.
Hisonotus montanus is a species of catfish in the family Loricariidae. It is known only from the Canoas River drainage in Brazil and reaches 4.5 cm SL. The specific epithet of this fish, montanus, derives from its tendency to be found at altitudes of roughly 850 m or 2789 ft above sea level, marking it as the species of Hisonotus that occurs at the highest elevation of those native to the Uruguay River basin.
Hisonotus vireo is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Jacuí River basin and the Lagoa dos Patos system in Brazil. The species reaches 4 cm SL.
Acanthobunocephalus scruggsi is a species of banjo catfish found in the tributaries of the lower Purus River. Due to gold mining in the region, the species could become more critically endangered and possibly even be driven into extinction.
Epactionotus advenus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Biguaçu River basin in the state of Santa Catarina in Brazil. The species reaches at least 3.54 cm in standard length. It was described in 2020 as part of a review of the genus Epactionotus conducted by Maria Laura S. Delapieve, Tiago Pinto Carvalho, and Roberto E. Reis. FishBase does not yet list this species.
