Native to continental China, the Korean peninsula, and southern Japan. Type locality is given only as 'Lakes and rivers, northern China', with the type series possibly originating from the Pai-ho River near Beijing. It has been widely introduced and is considered invasive elsewhere, including the Mekong river basin (records from Laos and Thailand), Salween river (Myanmar), northern Japan, Taiwan, Turkmeni...

This is the type species of the genus Aequidens and has the widest distribution of any member species. It exists in various colour forms depending on locality with variants from Ecuador and Peru being particularly sought after since they develop striking red (Ecuador) or orange (Peru) colouration on the lower part of the jaw, head and anterior portion of the belly whereas those from Brazil tend to have an overall grey/blue/green colouration, for example. Despite its type status it's long...

This species has something of a confused history having been previously been considered synonymous with both A. sophiae and A. fasciatus. Another species, A. chantrei is still listed as valid by some sources but is now known to be a junior synonym of A. danfordii. This became clear during a 1999 study in which the type specimens of A. danfordii were found to be indistinguishable from the Aphanius population living in the Sultan Swamps, the type locality of A. chantrei. You're unlikely t...

Apistogrammas are identified by the use of "A numbers"in a similar fashion to the "L number" system used to identify loricariids. Apistogramma brevis is identified as A168. Additionally, apistos are also grouped into type families and this species is the species type of the brevis group. Unlike some apistogramma species, a. brevis occurs only in a relatively small range and has not been found outside this. personata complex gibbiceps group...

Type locality is 'Furo do Lago São Francisco, 7°40'S, 72°39'W, tributary at left bank of Rio Juruá, Acre State, Brazil', and C. acrensis appears to be endemic to the rio Juruá basin. Unfortunately diagnostic characters cannot be provided since we've been unable to obtain the type description, and little has been written about this species since it was published.

Known only from the Ryukyu Islands, Japan, and thus far recorded from just 4 streams on Okinawa island and two on Iriomote island. The type series derived from both islands with Okinawa given as type locality. It may be more widely-distributed than this however, and was possibly transported to the Ryukyu Islands via the Kuroshio Current, an ocean current similar to the Gulf Stream transporting warm, tropical water northward from an area east of Taiwan past Japan towards the polar region.

Known only from the lower Amazon river basin, and possibly restricted to the Xingu and Tocantins watersheds. Type locality is ' Rio Santa Teresa, a western tributary of upper Rio Tocantins, Goiaz State, Brazil', referring to what is now known as Goiás state, central Brazil.

Recorded from Fujian, Guangdong, and Guangxi provinces in southwestern China, plus the islands of Hainan and Hong Kong. Type locality is 'Lian-Xian and Yang-Shan, Guangdong, China', corresponding to the Bei River drainage.

Apparently endemic to the upper Yangtze River basin, China. Type locality is 'mountain-stream fiowing into the Ichang gorge of the Yangtsze River'.

This species appears to be restricted to the Imo and Niger drainages in Nigeria but the full extent of its distribution is unclear. Type locality is 'Aba, Lower Niger, Nigeria', corresponding to the city of Aba in Abia state, southern Nigeria which lies on the Aba River, a tributary of the Imo. Nigeria has lost 95 % of its original rainforest cover, num...

Native to the Mekong River drainage in Laos (where Vientiane province represents the upper limit of its range), Thailand, Cambodia, and Vietnam, and the Tapi, Chao Phraya, and Mae Klong systems in Thailand. Type locality is '22 kilometers upstream from Phnom Penh, Tonle Sap River, Kandal Province, Cambodia'.

This species is widely-distributed in the Río Orinoco system in Brazil, Colombia and Venezuela plus coastal drainages in Guyana, Suriname and French Guiana including the Essequibo and Mazaruni. Type locality is 'Palital, Estado Guárico, Venezuela' which appears to correspond to a wetland called Esteros de Palital in the Aguaro-Guariquito National Park of Guárico state, northern Venezuela.

This species is normally referred to as A. paraguayensis, but that name has been considered a synonym of A. nattereri since 2003. Confusion remains however, as the type locality for the latter is 'Villa Bella', now known as Parintins, a settlement on the main Amazon river channel between Manaus and Santarém and many kilometres away from the majority of confirmed localities.

Type locality is close to a waterfall on the Ndian River in southwestern Cameroon, and appears restricted to the coastal plains either side of the border between Cameroon and Nigeria, including the Korup and Cross River National Parks.

The type material was derived from a commercial shipment of fishes from Leopoldville, now Kinshasa, Democratic Republic of Congo, and presumed to have been collected in the vicinity. The precise extent of its distribution unknown but appears extensive in the middle and lower Congo regions, with specimen collected from Lac Fwa (Sankuru River drainage, a Congo River tributary), many hundreds of kilometres west of Kinshasa, identified as belonging to this species.

The type series was derived from a commercial shipment and this species' natural range remains unconfirmed. It may be restricted to the area between the Kwango and Gamba rivers, the latter a tributary of the former, in western Democratic Republic of Congo. The Kwango is itself a tributary of the Kasai, an affluent of the Congo.

Type locality is the settlement of Bessou, Lobaye prefecture, Central African Republic, which lies within the Ubangi (also spelled Oubangui) River basin. The Ubangi is a major tributary of the Congo River and this species appears restricted to its middle section and thus probably extends into northern Republic of Congo and Democratic Republic of Congo.

Type locality is Malinga, located in the middle of the Du Chaillu mountain range in Ngounié province, southern Ghana. This lies very close to Republic of the Congo, and the species may also occur across the border.

Known only from the Batéké plateau region and surrounding area in southeastern Gabon where it's been recorded from the Léconi-Djouya and upper Mpassa rivers, these forming a portion of the much larger Ogooué basin. Type locality is '6 km west of Léconi', the latter presumably referring to the settlement of that name.

Appears restricted to the area between the lower Mitmele River, Equatorial Guinea and the lower Ogooué basin in Gabon, including coastal drainages such as the Mbei, Komo and Gabon watersheds in between. Type locality is 'Abanga River, between first and second rapids, Ogowe River system, Gabon', corresponding to the Abanga River bas...
