'''''Cyprinus''''' {{IPAc-en|s|ᵻ|ˈ|p|r|aɪ|n|ə|s}} is the [[genus]] of '''typical carps''' in family [[Cyprinidae]]. Most species in the genus are of East Asia origin with only the [[common carp]] (''C. carpio'') in Western Asia and Europe; this [[invasive species]] has also been [[Introduced species|introduced]] to many other regions around the world.<ref>{{cite web | title = Cyprinus carpio | url = http://www.iucngisd.org/gisd/speciesname/Cyprinus+carpio | publisher= [[ISSG]] | date = 4 October 2010 | access-date= 26 February 2017}}</ref> ''Cyprinus'' are closely related to some more [[barb (fish)|barb]]-like genera, such as ''[[Cyclocheilichthys]]'' and ''[[Barbonymus]]'' (tinfoils). The crucian carps (''[[Carassius]]'') of western [[Eurasia]], which include the [[goldfish]] (''C. auratus''), are apparently not as closely related.<ref>de Graaf ''et al.'' (2007)</ref>

This genus's most widespread and well-known member is the common carp (''C. carpio'') [[species complex]]. Although traditionally considered a single species, recent authorities have split the European and West Asian populations from the East Asian, with the latter named ''[[Cyprinus rubrofuscus|C. rubrofuscus]]'' ([[syn.]] ''C. carpio haematopterus'').<ref>{{cite iucn |author=Huckstorf, V. |date=2012 |title=''Cyprinus rubrofuscus'' |volume=2012 |page=e.T166052A1108337 |doi=10.2305/IUCN.UK.2012-1.RLTS.T166052A1108337.en |access-date=12 November 2021}}</ref><ref>{{FishBase | genus = Cyprinus | species = rubrofuscus | id=59920 | month = February | year = 2017}}</ref> Members of the species complex are famed as a [[food fish]] and have been widely traded and introduced since [[ancient history|antiquity]], but in certain areas has multiplied inordinately and become a [[Pest (organism)|pest]]. In its long use it has been [[domesticated]], and a number of [[breed]]s have been developed for food and other purposes. The [[koi]] (from [[Japanese (language)|Japanese]] ''nishikigoi'', 錦鯉) are well-known carp breeds, [[Selective breeding|selectively bred]] for being enjoyed by spectators from above. Strictly speaking, ''koi'' is simply the Japanese name of the East Asian carp.

The other [[species]] of typical carp are generally found in more restricted areas of eastern [[Asia]], centered on the [[Yunnan]] region. In some cases, they are [[Endemism|endemic]] to a single [[lake]], most notably [[Lake Erhai]], as well as [[Lake Dian]], [[Fuxian Lake]], [[Lake Jilu]], [[Lake Qilihu]], [[Lake Xingyun]] and [[Lake Yi-Lung]], which are all in Yunnan proper. Several of these species are seriously threatened and five are possibly already [[extinct]]: ''[[Cyprinus yilongensis|C. yilongensis]]'' (Lake Yi-Lung), ''[[Cyprinus yunnanensis|C. yunnanensis]]'' (Lake Qilihu),  ''[[Cyprinus daliensis|C. daliensis]]'' (Lake Erhai), ''[[Cyprinus megalophthalmus|C. megalophthalmus]]'' (Lake Erhai) and ''[[Cyprinus fuxianensis|C. fuxianensis]]'' (Fuxian Lake).<ref>{{cite iucn |author=Zhou, W. |date=2011 |title=''Cyprinus yilongensis'' |volume=2011 |page=e.T6179A12546193 |doi=10.2305/IUCN.UK.2011-2.RLTS.T6179A12546193.en |access-date=12 November 2021}}</ref><ref>{{cite iucn |author=Cui, K. |date=2011 |title=''Cyprinus yunnanensis'' |volume=2011 |page=e.T166169A6186294 |doi=10.2305/IUCN.UK.2011-2.RLTS.T166169A6186294.en |access-date=12 November 2021}}</ref><ref>Wang, Wang, Li, Du, Yang, Lassoie, and Hassan (2013).
