Xenurobrycon is a genus of characins from tropical South America. [1]
There are currently 6 recognized species in this genus: [1]
Characidae, the characids or characins is a family of freshwater subtropical and tropical fish, belonging to the order Characiformes. The name "characins" is the historical one, but scientists today tend to prefer "characids" to reflect their status as a by and large monophyletic group at family rank. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes that remain in the Characidae for the time being are the tetras, comprising the very similar genera Hemigrammus and Hyphessobrycon, as well as a few related forms such as the cave and neon tetras. Fish of this family are important as food and also include popular aquarium fish species.
Hyphessobrycon is a genus of freshwater fish in the family Characidae. These species are among the fishes known as tetras. The genus is distributed in the Neotropical realm from southern Mexico to Río de la Plata in Argentina. Many of these species are native to South America; about six species are from Central America and a single species, H. compressus is from southern Mexico.
Astyanax is a genus of freshwater fish in the family Characidae of the order Characiformes. Some of these fish, like many of their relatives, are kept as aquarium pets and known collectively as tetras. With around 150 described species and new ones being described yearly, this genus is among the largest of the entire order; Hyphessobrycon also has more than 145 species and which one is larger at any one time depends on whether more species have been recently described in one or the other. The blind and colorless cave tetra of Mexico is a famous member of the genus, but its taxonomic position is disputed: Some recognize it as part of the Mexican tetra and this is supported by phylogenetic evidence, but others recognize the cave form as a separate species, A. jordani.
Glandulocaudinae are a subfamily of tropical freshwater characin fish from Central and South America. In all species of this subfamily, a gland on their caudal fin is found almost exclusively in the males, which allows the release and pumping of pheromones; also, members of this subfamily have complex courtship behaviors which lead to insemination. The ecology and life history of these fish is complex yet little studied. Glandulocaudines are important as food fish for larger fish important for commercial and subsistence reasons.
The Curuá River is a tributary of the Iriri River in Pará state in north-central Brazil. It is a tributary of the Iriri River.
Moenkhausia is a genus of freshwater fish in the family Characidae native to tropical and subtropical South America. These are medium-sized tetras where the largest species only reach around 12 cm (4.7 in).
Bryconamericus is a genus of characins found in Central and South America.
Chrysobrycon is a genus of characins endemic to South America.
Diapoma is a genus of characins from tropical South America.
Glandulocauda is a genus of small characin freshwater fish that are endemic to Brazil, where restricted to the upper Paraná basin and coastal river basins in São Paulo state. The genus it is closely related to Lophiobrycon and Mimagoniates, and they form the tribe Glandulocaudini.
Hemigrammus is a genus of freshwater fish in the family Characidae native to South America and commonly seen in the aquarium trade. These are medium-small tetras where the largest species reach up to around 11 cm (4.3 in).
Hysteronotus megalostomus is a species of characin endemic to Brazil where it is found in the upper São Francisco River basin. This species is the only member of its genus.
Knodus is a genus of characins, small freshwater fish from South America.
Odontostilbe is a genus of characins from tropical Central and South America, with 17 currently recognized species:
Planaltina is a genus of characins endemic to Brazil.
Rhinopetitia is a genus of characins endemic to Brazil.
Tyttocharax is a genus of characins found in tropical South America.
Characidium is a genus of fish in the family Crenuchidae. They are mainly found in South America, but C. marshi is from Panama. They are small, slender fish that live on the bottom in flowing fresh waters and feed on small animals such as insects.
Curimatopsis is a genus of small South American fish in the family Curimatidae. They are native to freshwater habitats in the Amazon, Orinoco and Paraguay basins, as well as river of the Guianas.
Pyrrhulina is a genus of freshwater fishes found in tropical South America. Several of these species are popular aquarium fish.
