The Ash Meadows killifish is a species of killifish from the subfamily Empetrichthyinae, part of the family Goodeidae, which was first documented by C. H. Gilbert in 1893 and historically occupied numerous springs near Ash Meadows, Nye County, Nevada, United States. This species was last seen in 1948 and is believed to have gone extinct in the early 1950s, likely as a result of habitat alteration and competition with and predation by introduced crayfish Procambarus clarkii, mosquitofish, black mollies, and bullfrogs.

The mesh-scaled topminnow is a species of fish in the family Poeciliidae. The two population groups are a southern group of populations found in Angola, Botswana, the Republic of the Congo, Malawi, Mozambique, and Zambia and a northern population group found in Chad, the Central African Republic, the White Nile in South Sudan and Sudan and in the northern Democratic Republic of Congo. Its natural habitat is small streams and brooks, lakes, and swamps on floodplains where it lives among aquatic vegetation. This species was described by George Albert Boulenger as Haplochilus hutereaui in 1913 with the type locality being Dungu on the upper Uelé River in the Democratic Republic of Congo. Boulenger received the type from Armand Hutereau (1875-1914), who was the head of a Belgian ethnographic expedition to the Congo, so he honoured Hutereau in the specific name.
The yellowfin gambusia is a species of fish in the family Poeciliidae. It is endemic to the Rio Conchos of Chihuahua, Mexico, where it is known as guayacon de san gregorio. This species was described in 1957 by Clark Hubbs and Victor G. Springer with the type locality given as El Ojo de San Gregorio in Chihuahua. The specific name of this fish honours the Mexican ichthyologist José Alvarez del Villar (1903-1986) for his work on the fishes of Mexico and for his assistance to Clark and Springer.
The Big Bend gambusia is a rare species of fish in the family Poeciliidae. It is endemic to the Big Bend region of the Rio Grande of the United States and Mexico. The only known remaining population is in a protected pond in the Big Bend National Park.
Gambusia hurtadoi, also known as crescent gambusia, is a species of fish in the family Poeciliidae. It is endemic to Chihuahua in Mexico, where it is known as guayacon de Hacienda Dolores. It grows to 3.5 cm (1.4 in) total length. The species was described in 1957 by Carl Leavitt Hubbs and Victor G. Springer with the type locality given as El Ojo de la Hacienda Dolores, 7 miles south of Jiminez, Chihuahua, the spring to which this species is endemic. Hubbs and Springer honoured the Mexican Leopoldo Hurtado Olin of the Departamento de Economía in Chihuahua for his assistance during their collecting expedition to Chihuahua in June 1951. Hurtado Olin also informed Hubbs and Springer of the location of El Ojo de la Hacienda Dolores.
The eastcoast lampeye is a species of fish in the family Poeciliidae. It is endemic to coastal Kenya and Tanzania, where found in brackish water, mangrove swamps, pools, lagoons and river deltas. It reaches up to 5 cm (2.0 in) in total length. This fish was described by Ernst Ahl as Haplochilichthys stuhlmanni with the type locality given as Tanganyika Territory. The specific name honours the co-leader of the German East Africa Expedition (1889-1892) on which type was collected, Franz Ludwig Stuhlmann (1863-1928) of the German Colonial Service.
The northern platyfish is a species of fish in the family Poeciliidae. It is endemic to Mexico. It was named in honor of Myron Gordon by Robert Rush Miller and W. L. Minckley who discovered it with Carl Hubbs on a 1961 expedition.

Alfaro is a genus of poeciliid fishes endemic to Central America. The generic name honours the Costa Rican archaeologist, geologist, ethnologist, zoologist and Director of the National Museum of Costa Rica, Anastasio Alfaro (1865-1951).
The pike topminnow, also known as the top minnow, is a species of poeciliid found from Mexico to Costa Rica. It has also been introduced to Florida, USA. The female of the species grows to a total length of 20 cm (7.9 in), with males growing to 10 cm (3.9 in). It is the only known member of its genus. Unlike most poeciliids, this is a highly specialized predator, with an extremely flexible upper jaw that enables it to take very large prey items for its size. The pike topminnow was described in 1860 by Austrian ichthyologist Rudolf Kner, who gave the type locality as Belize, which is reflected in this species' specific name.
Carlhubbsia is a genus of poeciliids native to Guatemala and Mexico. The name of this genus honours the American ichthyologist Carl Leavitt Hubbs (1894-1979) who originally named the genus Allophallus, a name which was preoccupied by a genus of Diptera.

The Dead Sea toothcarp is a subspecies of the Arabian toothcarp that is endemic to the Dead Sea basin, although molecular evidence suggests that it should be regarded as a species. It is threatened by water fluctuation, and the introduction of cichlids and Gambusia. The sub-specific name of this fish honours the Scottish surgeon and naturalist John Richardson (naturalist) (1787-1865) who first reported killifish in the Dead Sea basin. The Dead Sea toothcarp -- has been on the red list of the International Union for Conversation of Nature since 2014.
The Nile killifish, also known as the Nile lampeye, is a species of killifish from the family Poeciliidae. It is found in the White Nile drainage in Sudan, the Nile Delta in Egypt, the Wembere and Malagarasi Rivers in Tanzania and in the Lake Victoria basin in Uganda and Tanzania. However, it is thought to have been extirpated from Egypt, the introduction of alien poecilid fish, agricultural pollution and increasing salinity are all thought to have contributed to its local extinction in the Nile Delta.
Aapticheilichthys is a monotypic genus of killifish from the family Poeciliidae, the sole member being Aapticheilichthys websteri. A. websteri was found by the American fish breeder Kent Webster after which the species was named. The type locality was Akaka Camp on the western coastal plain of Gabon.
