Xenocyprinae,[1] is a contentious subfamily of the family Cyprinidae, the carp and minnow family, originally from eastern Asia.
Genera
[edit]The 5th edition of Fishes of the World assigns the following genera to this subfamily:[2]
- Aristichthys Oshima, 1919
- Hypophthalmichthys Bleeker, 1860
- Xenocypris Günther, 1868
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]
- Distoechodon Peters, 1881
- Hypophthalmichthys Bleeker, 1860
- Metzia Jordan & Thompson, 1914
- Plagiognathops Berg, 1907
- Pseudobrama Bleeker, 1870
- Xenocypris Günther, 1868
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]
Taxonomy
[edit]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]
