Kneria is a genus of small fish in the family Kneriidae. All the species in this genus are restricted to Africa.
Named in honor of Austrian ichthyologist Rudolf Kner (1810-1869) [2]
The following species are inclided in this genus: [3]
However there is another species, known as the Southern Kneria (Kneria sp. 'South Africa'), [4] occurring only in the headwaters of a few tributaries of the Crocodile River, in the Inkomati River system of South Africa. [5] It was initially declared a Critically Endangered species on the IUCN Red List in 2007, [4] [6] but it was reassessed in 30 November 2016 as Endangered. [7]
Steatocranus is a genus of small rheophilic cichlids mostly native to the Congo River Basin in DR Congo/Congo Brazzaville, although one species, S. irvinei, is restricted to the Volta River in Ghana and Burkino Faso, and it belongs in a separate genus. There are also at least c. 10 undescribed species in the Congo River basin awaiting scientific description.
Astatoreochromis is a small genus of haplochromine cichlids endemic to riverine habitats in East Africa. Tilapia bemini, usually placed in the tilapiines, may be rather close to this genus. However, extensive hybridization capabilities of African cichlids seriously confound analyses of phylogeny based on mtDNA, while morphological analyses tend to yield little information due to widespread parallel evolution.
Mastacembelus is a genus of many species of spiny eel fish from the family Mastacembelidae. They are native to Africa and Asia. Most are found in rivers and associated systems, but there are also species in other freshwater habitats and a particularly rich radiation is found in the Lake Tanganyika basin with 15 species. A few species can even occur in brackish water.
Hepsetus is a genus of African fishes, the African pikes or African pike characins, in the order Characiformes. It is the sole genus in the family Hepsetidae. It was long believed that only a single widespread species existed, H. odoe, but studies in 2011–2013 have shown that this species is restricted to parts of West and Central Africa. The well-known species of southern Africa, including Kafue River, is Hepsetus cuvieri. These predatory fish reach up to 44 cm (17 in) in length.
Haplochromis is a ray-finned fish genus in the family Cichlidae. It has been used as the default "wastebin taxon" for Pseudocrenilabrinae cichlids of the East African Rift, and as such became the "largest" fish "genus". Many of these cichlids are popular aquarium fishes; like similar Haplochromini they are known as "haplos", "happies" or "haps" among aquarium enthusiasts.
Pseudobarbus is a ray-finned fish genus in the family Cyprinidae. The type species is Burchell's redfin. The scientific name is derived from the Ancient Greek pseudes ("false") and the Latin word barbus. This genus contains some of the South African redfins. It was originally proposed as a subgenus, but has since been found worthy of recognition as a full genus.
Marcusenius is a genus of the elephantfish group native to Africa. Its members are highly diverse in size, with the smallest species reaching less than 15 cm (6 in) and the largest more than 1 m (3.3 ft).
Microctenopoma is a genus of fish in the Anabantidae family. They are native to Africa. Microctenopoma has been included in Ctenopoma in the past; unlike that genus, they are bubblenest builders, and the males defend the eggs and fry until they are free swimming.
Ophisternon is a genus of swamp eels found in fresh and brackish waters in South and Southeast Asia, New Guinea, Australia, Middle America and West Africa. Two species are blind cave-dwellers.
Parakneria is a genus of fish in the family Kneriidae, with 15 species, all of which are restricted to Africa.
The Kneriidae are a small family of freshwater gonorhynchiform fishes native to sub-Saharan Africa.
Labeobarbus is a mid-sized ray-finned fish genus in the family Cyprinidae. Its species are widely distributed throughout eastern Africa and especially southern Africa, but also in Lake Tana in Ethiopia. A common name, in particular for the southern species, is yellowfish. The scientific name refers to the fact that these large barbs recall the fairly closely related "carps" in the genus Labeo in size and shape. As far as can be told, all Labeobarbus species are hexaploid. One species, L. microbarbis from Rwanda, is known to have gone extinct in recent times.
Cromeria is a small genus of fish in the family Kneriidae found in fresh waters in the Sudan, Mali, and Guinea in the Nile and Niger Rivers of Africa. These reach a length of up to 4.4 cm. The currently recognized species are:
Heteromormyrus is a genus of freshwater ray-finned fishes belonging to the family Mormyridae, the elephantfishes. These fishes are found in southern and central Africa in Angola, Namibia, the Democratic Republic of the Congo and, maybe, Zimbabwe.
Microthrissa is a genus of freshwater ray-finned fishes belonging to the family Dorosomatidae, which also includes the gizzard shads and sardinellas. The species in this genus are endemic to Africa.
Odaxothrissa, the fangtooth pellonulines, is a genus of fresh-water fish in the family Dorosomatidae. All the extant species in this genus are found in tropical Africa.
Potamothrissa is a genus of fish belonging to the family Dorosomatidae, which also includes the gizzard shads and sardinellas. These fishes are found in Africa. It currently contains three species.
Parachaenichthys is a genus of marine ray-finned fish belonging to the family Bathydraconidae, the Antarctic dragonfishes. They are found in the Southern Ocean around Antarctica.
Enteromius is a genus of small to medium-sized cyprinid fish native to tropical Africa. Most species were placed in the genus Barbus.
Smiliogastrinae is a subfamily of freshwater ray-finned fishes belonging to the famly Cyprinidae, the family which includes the carps, barbs and relalted fishes. The fishes in this genus are found in Africa and Asia and are commonly referred to as barbs.
