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.

Loricariidae
The Loricariidae is the largest family of catfish (order Siluriformes), with 92 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as " plecos", notably the suckermouth catfish, ''Hypostomus plecostomus'', and are popular as aquarium fish. Common names Members of the family Loricariidae are commonly referred to as loricariids, suckermouth armoured catfishes, or armoured catfish. The name "plecostomus", and its shortened forms "pleco" and "plec", are used for many Loricariidae, since ''Plecostomus plecostomus'' (now called ''Hypostomus plecostomus'') was one of the first loricariid species imported for the fish-keeping hobby. Some loricariids are not normally considered "plecostomus", such as ''Farlowella'' catfish. In their native range, these fish are known as ''cascudos'' ...

Hypostomini
''Hypostomus'' is a genus of catfish in the family Loricariidae. They are native to tropical and subtropical South America. '' H. plecostomus'' is the popular freshwater aquarium fish formerly known as ''Plecostomus plecostomus''. The taxonomic structure of the Loricariidae is still being expanded by scientists. ''Hypostomus'' is a highly species-rich and widely distributed catfish genus. [Baidu] |

Corymbophanes
''Corymbophanes'' is a genus of armored catfish native to South America where they are only known from Guyana. ''Corymbophanes'' was originally placed in its own tribe Corymbophanini, but the first comprehensive molecular phylogenetic analysis of the subfamily Hypostominae found ''Corymbophanes'' to be nested within the tribe Ancistrini. Taxonomy ''Corymbophanes'' and its type species, ''C. andersoni'', were first described in 1909 by Carl H. Eigenmann. In 2000, they were redescribed along with the description of a new species, ''C. kaiei''. In 2004, the tribe Corymbophanini was erected. ''Corymbophanes'' represents an old lineage as it lacks many of the characteristics of the rest of the subfamily Hypostominae. This group probably has a basal position within the subfamily. Species There were previously two recognized species in this genus. A third species was described in a 2020 study. * '' Corymbophanes ameliae'' Lujan, Armbruster, Werneke, Teixeira & Lovejoy, 2020 * ...

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 ...

Rhinelepini
Rhinelepini is a tribe of fishes in the subfamily Hypostominae of the armored suckermouth catfish family Loricariidae. Taxonomy This tribe is a well diagnosed monophyletic group currently containing three genera: '' Pogonopoma'', '' Pseudorinelepis'', and '' Rhinelepis''. When the tribe was first described, ''Pogonopomoides'' was a valid genus, but it is now a synonym of ''Pogonopoma''. ''Pseudorinelepis'' is the most basal, and ''Rhinelepis'' and ''Pogonopoma'' are more derived sister groups. Appearance and anatomy Rhinelepini species are generally medium to large-sized Loricariids. Rhinelepini species are unique among Loricariidae for having a normal, circular iris as opposed to the bilobed, omega iris. These species end to have relatively thick armor plates on their bodies. In Iquitos, Peru, '' Pseudorinelepis genibarbis'' is known as ''carachama sin costilla'', which actually means "Loricariid without ribs"; this refers to the trait that it shares with other Rhinelepin ...

Pterygoplichthys
''Pterygoplichthys'', sometimes collectively known as janitor fish, is a genus of South American armored catfishes. These fish are commonly known as sailfin armoured catfish or sailfin plecs, especially in the aquarium trade. Etymology ''Pterygoplichthys'' is derived from the Greek ''πτέρυγ-'' (''pteryg-''), meaning "wing", (''hoplon'') - weapon and ''ἰχθύς'' (''ichthys'') meaning "fish". Taxonomy ''Pterygoplichthys'' has undergone much shifting in the past decades. Previously ''Liposarcus'', ''Glyptoperichthys'' and ''Pterygoplichthys'' had been named as separate genera. Since then, these genera were recognized as synonyms of ''Pterygoplichthys'' by Armbruster, as the few differences between the genera were not deemed great enough to validate ''Glyptoperichthys'' and ''Liposarcus'', and that recognizing these separate genera would leave neither ''Pterygoplichthys'' nor ''Glyptoperichthys'' as monophyletic. Species There are currently 16 recognized species in thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pterygoplichthyini
Pterygoplichthyini is a tribe of catfishes ( order Siluriformes) of the family Loricariidae. It includes two genera, ''Pterygoplichthys'' and the currently undescribed genus referred to as the ''Hemiancistrus annectens'' group, This group was earlier misspelled as Pterygoplichthini. Pterygoplichthyines are known from nearly the entire range of loricariids except for the Guyanas and coastal streams in southeastern Brazil. although later work by the same authority, and his co-authors, placed this group among the genus ''Hypostomus''.

Panaque Nigrolineatus
''Panaque nigrolineatus'', the royal panaque, royal plec, or royal pleco, is an herbivorous freshwater armored catfish native to Brazil, Colombia and Venezuela where it occurs in the Orinoco and Amazon basins. It is known for being one of the few fish that digest wood. It grows to a length of and is a popular aquarium fish. Anatomy and appearance The royal panaque is closely related to the popular plecostomus catfish kept in many aquaria as an algae eater. While the royal panaque also eats algae, it is best known among biologists as being among the very few fish capable of eating and digesting wood. It does so using symbiotic gut bacteria. Royal panaques are light grey in colour patterned with dark grey squiggles. They have red eyes and the dorsal fins are edged with cream or gold. The body is encased in heavy armour, except for the belly, which is soft. This armour is made of strong plates of skin, not scales. Royal panaques can grow to 43 centimetres (17 in) in le ...

Ancistrus
''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. Taxonomy The type species is ''Ancistrus cirrhosus''. This genus is the largest genus within the tribe Ancistrini. The name ancistrus derives from the Ancient Greek ''agkistron'' "hook" – a reference to the form of the cheek odontodes. The genera ''Pristiancistrus'', ''Thysanocara'' and ''Xenocara'' are now synonyms of ''Ancistrus''. Description ''Ancistrus'' species show all the typical features of the Loricariidae. T ...
