Xenocyprinae, [1] is a contentious subfamily of the family Cyprinidae, the carp and minnow family, originally from eastern Asia.
The 5th edition of Fishes of the World assigns the following genera to this subfamily: [2]
The taxonomy of the Cyprinids is somewhat contentious and other authorities differ with the above, for example the following genera are assigned to the subfamily Xenocyprinae on Fishbase or the 2018 phylogenetic study: [1] [3]
A potential fossil genus of the Xenocyprinae is Planktophaga from the middle-late Eocene of Vietnam. Although initially classified under the East Asian group of Leuciscinae sensu lato (as Hypophthalmichthys was previously classified under it), it has unique pharyngeal teeth only shared with Hypophthalmichthys, and thus may represent a basal member of the group. Fossil teeth of indeterminate xenocyprines were found from the same site. [4] [5]
Cyprinidae is a large, widespread and diverse family of, mainly, freshwater ray-finned fish and the taxonomy of the family has not yet been fully resolved and the subfamilies do not appear to have a single accepted taxonomy. Some authorities place the genera above in the larger subfamilies Oxygasterinae or Xenocypridinae. [6] However, genetic and morphological studies have supported the view that the five genera currently assigned to the subfamily Xenocyprinae form a monophyletic grouping. [7]
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species; only 1,270 of these remain extant, divided into about 200 valid genera. Cyprinids range from about 12 mm (0.5 in) in size to the 3 m (9.8 ft) giant barb. By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word kyprînos.
Serranidae is a large family of fishes belonging to the order Perciformes. The family contains about 450 species in 65 genera, including the sea basses and the groupers. Although many species are small, in some cases less than 10 cm (3.9 in), the giant grouper is one of the largest bony fishes in the world, growing to 2.7 m in length and 400 kg (880 lb) in weight. Representatives of this group live in tropical and subtropical seas worldwide.
Cypriniformes is an order of ray-finned fish, which includes many families and genera of cyprinid fish, such as barbs, gobies, loaches, botias, and minnows. Cypriniformes is an “order-within-an-order”, placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11-12 families, over 400 genera, and more than 4,250 named species; new species are regularly described, and new genera are recognized frequently. Cyprinids are most diverse in South and Southeast Asia, but are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.
Phoxinus is a genus of freshwater fish in the family Leuciscidae of order Cypriniformes, and the only members of the subfamily Phoxininae, or Eurasian minnows. The type species is Phoxinus phoxinus. The other species in this genus are also commonly known as minnows. The name "minnow" was what early English fisherman used to describe "small and insignificant". The genus Phoxinus is found throughout Eurasia, and includes 21 known species. Previously, members of the North American genus Chrosomus were also believed to form part of this genus.
Puntius is a genus of small freshwater fish in the family Cyprinidae native to South Asia and Mainland Southeast Asia, as well as Taiwan.
Barbonymus is a ray-finned fish genus in the family Cyprinidae, containing some barb species. The genus was only established in 1999, with the tinfoil barb as type species; thus, these fish are sometimes collectively called tinfoils. The new genus was established in recognition of the fact that some large Asian "barbs", formerly rather indiscriminately lumped in Barbus, Barbodes and Puntius, form a distinct evolutionary lineage.
Garra is a genus of fish in the family Cyprinidae. These fish are one example of the "log suckers", sucker-mouthed barbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 160 species of garras are native to Asia, but about one-fifth of the species are from Africa.
Onychostoma is a genus of cyprinid fish found in eastern Asia.
The bitterling-like cyprinids form the cyprinid subfamily Acheilognathinae. This subfamily contains seven genera, although the Khanka spiny bitterling is often placed in Acheilognathus, and at least 75 described species to date. Over half of the species are in the genus Acheilognathus.
Labeoninae is a doubtfully distinct subfamily of ray-finned fishes in the family Cyprinidae of order Cypriniformes. They inhabit fresh water and the largest species richness is in the region around southern China, but there are also species elsewhere in Asia, and some members of Garra and Labeo are from Africa. They are a generally very apomorphic group, perhaps the most "advanced" of the Cyprinidae. A common name for these fishes is labeonins or labeoins.
Barbinae are a subfamily of fish included in the family Cyprinidae. The taxonomy for this group has not been entirely worked out as some genera historically considered within it are still considered incertae sedis with respect to being a member of the family, and may be included here, while others may be moved to other subfamilies.
Leuciscinae is a subfamily of the freshwater fish family Cyprinidae, which contains the true minnows.
Loaches are fish of the superfamily Cobitoidea. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidea comprise about 107 genera divided among 9 families.
Bangana is a genus of fish in the family Cyprinidae, the carps and minnows. It is distributed across much of southern and eastern Asia. Species live mainly in the flowing waters of tropical and subtropical rivers.
The danionins are a group of small, minnow-type fish belonging to the family Cyprinidae. Species of this group are in the genera clades Danio and Devario, based on the latest phylo-genetic research by Fang et al in 2009. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Fishes of the danio clade tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. Species within the devario clade tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans.
Gobioninae is a monophyletic subfamily of Eurasian cyprinid fishes. A species-rich subfamily, it is divided into five tribes: Gobionini, Pseudogobionini, Hemibarbini, Coreiini, and Sarcocheilichthyini.
Laubuka is a genus of cyprinid fish found in South and Southeast Asia.
Alburninae is a small subfamily of the carp and minnow family of ray-finned fish, the Cyprinidae. The genera in this subfamily were previously considered to be part of the Leuciscinae, but if the three Alburninae genera are included in that subfamily, it is paraphyletic. The Alburninae are still a contentious group and some authorities consider it to consist of two distinct clades, making it biphyletic.
Squaliobarbinae is a small subfamily of the carp and minnow family, Cyprinidae, which consists of three monotypic genera which have their natural distributions in eastern Asia. Two species, the grass carp and the black carp, have been introduced to other parts of the world for weed control and aquaculture. They are large cyprinids characterised by an enlarged subtemporal fossa, the palate articulating with the supraethmoid, an enlarged intercalar bone in the cranial vault, and a divided levator posterior muscle.
