Xenocyprididae


Xenocyprididae is a family of freshwater ray-finned fishes, commonly called the East Asian minnows or sharpbellies. They have a natural distribution in Asia. This taxon, sometimes spelt Xenocypridae, was previously regarded to be a subfamily, Xenocyprinae, of the family Cyprinidae. Cyprinidae sensu lato is now divided into a number of smaller families within the suborder Cyprinoidei, in the order Cypriniformes.

Taxonomy

Xenocyprididae was previously considered to be a part of the family Cyprinidae, along with the Danionidae, Leuciscidae, Tincidae, and other related fish taxa. Eschmeyer's Catalog of Fishes places all of these groups, formerly considered to be subfamilies of the Cyprinidae sensu lato, in the large, widespread and diverse suborder Cyprinoidei, consisting mainly of freshwater ray-finned fish. This conforms with the classification adopted by other authorities. The suborder Cyprinoidei is classified in the order Cypriniformes.

The following fossil genera are known:
  • †Dezaoia Su, Chang & Chen, 2021
  • †Ecocarpia Chen, Fang & Chang, 2005
  • †Eoctenopharyngodon Su, Chang & Chen, 2021
  • †Eoxenocypris Chang, Chen & Tong, 1996
  • †Iquius Jordan, 1919
  • †Ikiculter Yabumoto, 2010
A potential fossil genus of the Xenocyprinae is †Planktophaga Böhme et al., 2014 from the middle-late Eocene of Vietnam. Although initially classified under the East Asian group of Leuciscinae sensu lato, 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.
