Pseudacanthicus
''Pseudacanthicus'' is a genus of medium to large-sized suckermouth armored catfishes native to South America, where found in the Amazon and Orinoco basins, as well as rivers of the Guianas. They are primarily found in fast-flowing waters, sometimes relatively deep. They are sometimes kept in aquariums. Species There are currently 8 recognized species in this genus: * '' Pseudacanthicus fordii'' ( Günther, 1868) * '' Pseudacanthicus histrix'' (Valenciennes, 1840) * '' Pseudacanthicus leopardus'' ( Fowler, 1914) * '' Pseudacanthicus major'' Chamon & Costa e Silva, 2018Chamon, Carine C. ; and Thiago Costa e Silva (2018).

Pseudacanthicus Pirarara
''Pseudacanthicus pirarara'' is a species of catfish in the family Loricariidae native to South America. It was described in 2016 by Carine C. Chamon of the Federal University of Tocantins and Leandro M. de Sousa of the Federal University of Pará, primarily on the basis of the species' unique coloration and patterning.Chamon, C. C., & Sousa, L. M. (2017). A new species of the leopard pleco genus Pseudacanthicus (Siluriformes: Loricariidae) from the Rio Xingu, Brazil. ''Journal of fish biology'', ''90''(1), 356–369. https://doi.org/10.1111/jfb.13184 Its specific epithet, ''pirarara'', derives from a Tupi language, Tupi word meaning "macaw-fish", which is frequently used in Brazil to refer to the redtail catfish. It is known that ''P. pirarara'' is referred to as the ''assacu-pirarara'' by Brazilian fishermen, alluding both to its coloration and its spines, as ''assacu'' refers to the spine-covered tree ''Hura crepitans'' (also known as the sandbox tree).

Pseudacanthicus Pitanga
''Pseudacanthicus pitanga'' is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Tocantins River basin in Brazil. The species reaches 30 cm (11.8 inches) SL. It was described in 2015 by Carine C. Chamon of the Federal University of Tocantins on the basis of distinctive coloration and morphology. Its specific epithet, ''pitanga'', is derived from a Tupi-Guarani word meaning "red", in reference to the color of the species' fins. ''P. pitanga'' appears in the aquarium trade, where it is often referred to either as the red-fin cactus pleco or by its associated L-number, which is L-024. It is reportedly bred in captivity and exported to multiple countries for aquarium use, especially the United States and countries in Europe Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions.

Ancistrini
Ancistrini is a tribe of catfishes of the family Loricariidae. Most are restricted to tropical and subtropical South America, but there are also several genus (''Ancistrus'', '' Chaetostoma'', ''Hemiancistrus'' and ''Lasiancistrus'') in southern Central America. Taxonomy Ancistrini have previously been considered a loricariid subfamily. However, the subfamily Hypostominae would be paraphyletic if Ancistrinae continued to be recognized. To continue recognizing the monophyly of this group while returning it to Hypostominae, Hypostominae was broken into several tribes. Pterygoplichthyini is sister to the tribe Ancistrini, which shares the derived presence of an evertible patch of plates on the cheek. Description Most Ancistrini species (except for some ''Pseudancistrus'' and ''Spectracanthicus'') can be separated from all other loricariids except the Pterygoplichthyini by the presence of evertible cheek plates with hypertrophied odontode Odontodes, or dermal teeth, are hard structu ...

Undescribed Species
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a '' nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp"., but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, ichthyologist, and herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Duméril of Paris. His wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
