Loricariini
Loricariinae is a subfamily of the family Loricariidae of catfish (order Siluriformes). This subfamily is divided into two tribes and about 30 genera. They are mainly native to freshwater habitats in South America, but there are also several species (in genera '' Crossoloricaria'', '' Dasyloricaria'', '' Fonchiiichthys'', '' Rineloricaria'', '' Spatuloricaria'', ''Sturisoma'' and '' Sturisomatichthys'') in Panama and a single (''Fonchiiichthys'') in Costa Rica.Angulo; Garita-Alvarado; Bussing; and López (2013). Annotated checklist of the freshwater fishes of continental and insular Costa Rica: additions and nomenclatural revisions.'' Check List 9(5): 987–1019. Taxonomy Loricariinae was first described in 1831. Later, in 1979, many genera were described and Loricariinae was divided into four subfamilies: Loricariini, Harttiini, Farlowellini, and Acestridiini. Eventually, the genera of Acestridiini was included under Hypoptopomatinae and genera of Farlowellini was reclassified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crossoloricaria
''Crossoloricaria'' is a genus of armored catfish native to South America with one species ranging into Central America. Taxonomy ''Crossloricaria'' is classified in the ''Pseudohemiodon'' group in the tribe Loricariini of the subfamily Loricariinae. This genus is poorly diagnosed and is in need of revision. Its only diagnostic character (incomplete abdominal cover consisting of a double median row of plates) is shared by two other representatives of the Pseudohemiodon group, '' Apistoloricaria'' and ''Rhadinoloricaria''. On top of this, ''C. rhami'' has a complete abdominal cover of plates, rendering this diagnostic feature invalid. ''Crossoloricaria'' also has some traits such as lip structure and barbel length that places it closer to '' Pseudohemiodon''. Species There are currently five recognized species in this genus: * '' Crossoloricaria bahuaja'' F. Chang & E. Castro, 1999 * '' Crossoloricaria cephalaspis'' Isbrücker, 1979 * '' Crossoloricaria rhami'' Isbrücker & ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spatuloricaria
''Spatuloricaria'' is a genus of armored catfishes native to South America and Panama. ''Spatuloricaria'' is in need of revision, as species boundaries and distributions are poorly known. The phylogenetic position of ''Spatuloricaria'' remains uncertain. ''Spatuloricaria'' has been placed at the base of a clade including representatives of the ''Loricaria'' and ''Pseudohemiodon'' groups. Its dentition, with few teeth on the premaxillae, and its abdominal cover consisting of minute disjointed platelets resembles that of some representatives of the ''Loricaria'' group. Conversely, the papillose surface of the lips and sexually dimorphic features are more characteristic of the ''Rineloricaria'' group. This genus is distributed in the northwestern part of the South American subcontinent, in drainages of the Pacific and Atlantic Slopes of the Andes. Several species occur also in the upper Amazon River basin, upper Paraguay, and São Francisco River basins. Sexual dimorphism incl ...

Brochiloricaria
''Brochiloricaria'' is a small genus of armored catfishes native to South America. Species There are currently two recognized species in this genus: * '' Brochiloricaria chauliodon'' Isbrücker, 1979 * '' Brochiloricaria macrodon'' ( Kner, 1853) Appearance and anatomy ''Brochiloricaria'' is morphologically very similar to ''Loricaria'' and can be distinguished from the latter only by its teeth characteristics; in ''Brochiloricaria'', the teeth are very long and of equal size on both jaws, while in ''Loricaria'' the premaxillary teeth are almost two times longer than dentary In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone ... teeth. However, dentition may not be a reliable characteristic to differentiate to genera, so Brochiloricaria may actually be a synonym of ''Loricaria''. ...

Rineloricaria
''Rineloricaria'' (from the Greek, ''rhinos'' meaning ''nose'', and the Latin, ''lorica'' meaning ''cuirass of leather'') is a genus of freshwater tropical catfish ( order Siluriformes) 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. Taxonomy This genus was described by Pieter Bleeker in 1862, with ''R. lima'' as the type species. This genus is by far one of the most speciose of the subfamily Loricariinae, containing about 30 species. On the other hand, it is one of the least resolved genera. In 2008, 14 new species were added to this genus. ''Hemiloricaria'', '' Fonchiiichthys'', and ''Leliella'' been variably considered synonyms of ''Rineloricaria''; these gene ...

Dasyloricaria
''Dasyloricaria'' is a genus of armored catfishes native to Central and South America. The distribution of these species includes the northwestern South America on the Pacific slope of Colombia and Panama. Its distribution is restricted to the Pacific slope of the Andes, which is a unique pattern of distribution within the subfamily. Species There are currently 3 recognized species in this genus: * '' Dasyloricaria filamentosa'' ( Steindachner, 1878) * '' Dasyloricaria latiura'' ( C. H. Eigenmann & Vance, 1912) * '' Dasyloricaria paucisquama'' Londoño-Burbano & R. E. dos Reis, 2016 Londoño-Burbano, A. & Reis, R.E.

Caudal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod ...

Dorsum (biology)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of ana ...

Odontodes
Odontodes, or dermal teeth, are hard structures found on the external surfaces of animals or near internal openings. They consist of a soft pulp surrounded by dentine and covered by a mineralized substance such as enamel, a structure similar to that of teeth. They generally do not have the same function as teeth, and are not replaced the same way teeth are in most fish. In some animals (notably catfish), the presence or size of odontodes can be used in determining the sex. Odontodes typically cover the body of chondrichthyans (cartilaginous fishes), while mineralized dermal scales are characteristic of bony fishes. During the evolution to bony fishes, ancestral odontodes have been modified to become dermal scales, including elasmoid scales in teleost Teleostei (; Greek ''teleios'' "complete" + ''osteon'' "bone"), members of which are known as teleosts ), is, by far, the largest infraclass in the class Actinopterygii, the ray-finned fishes, containing 96% of all extant specie ...

Harttia
''Harttia'' is a genus of armored catfishes native to South America. The genus name comes from Charles Frederick Hartt (1840-1878), a geologist, paleontologist and naturalist, who collected the many specimens during the Thayer Expedition to Brazil in the years 1865-1866. Taxonomy As of 1997, ''Harttia'' was considered a monophyletic taxon. However, ''Harttia'' is in need of revision. For example, the synonymy of '' Cteniloricaria'' with ''Harttia'' was questionable because it rested solely on the characteristics of ''Harttia fowleri'' without considering the type species of ''Cteniloricaria''. Species There are currently 23 recognized species in this genus: * '' Harttia absaberi'' Oyakawa, Fichberg & Langeani, 2013Oyakawa, O.T., Fichberg, I. & Langeani, F. (2013)''Harttia absaberi'', a new species of loricariid catfish (Siluriformes: Loricariidae: Loricariinae) from the upper rio Paraná basin, Brazil.
