Pseudancistrus
''Pseudancistrus'' is a genus of suckermouth armored catfishes native to South America. Taxonomy ''Pseudancistrus'' is a genus in the tribe Ancistrini of the subfamily Hypostominae. It was described by Pieter Bleeker in 1862, and redescribed by Jonathan Armbruster in 2004. Currently, there are 18 recognized species distributed in northern South America, with the inclusion of the genera ''Lithoxancistrus'', the species formerly known as ''Hemiancistrus megacephalus'', as well as the recently described ''Pseudancistrus corantijniensis''. There is no single morphological feature which distinguishes the group from related genera. Despite this, ''Pseudancistrus'' is generally recognized as a monophyletic group. Within the genus there is what is called the ''P. barbatus'' group. This group comprises Guyanese derived ''Pseudancistrus'' bearing hypertrophied odontodes along the snout and nonevertible cheek plates. It includes the five species ''P. barbatus'', ''P. corantijniensis'', '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pseudancistrus Barbatus
''Pseudancistrus barbatus'', commonly known as the bearded catfish, is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the basins of the Oyapock, the Mana River, the Maroni, the Suriname River, the Courantyne River, and the Essequibo River. Within its range, the bearded catfish is typically found in rocky, fast-flowing rapids Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Rapids are hydrological features between a ''run'' (a smoothly flowing part of a stream) and a ''cascade''. .... The bearded catfish reaches 20 cm (7.9 inches) in standard length, and it is believed that the length of the snout bristles on a male individual of the species may reflect the individual's hierarchic status within the population. It is known to be fished in shallow areas within its range using harpoons or bows. The species also occasionally appears in ...

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 ...

Hypostominae
The Hypostominae are a subfamily of catfishes of the family Loricariidae. Most members are restricted to tropical and subtropical South America, but there are also several species (in genera ''Ancistrus'', '' Chaetostoma'', ''Lasiancistrus'', '' Leptoancistrus'' and ''Hemiancistrus'') in southern Central America. ''Hypostomus plecostomus'', which is popular in the aquarium trade, has been introduced to several regions far from its native range. Studies conducted with representatives of some genera of Hypostominae showed, within this group, the diploid number ranges from 2n = 52 to 2n = 80. However, the supposed wide karyotypic diversity the family Loricariidae or the subfamily Hypostominae would present is almost exclusively restricted to the genus ''Hypostomus'', and the species from the other genera had a conserved diploid number.
