Pseudoxiphophorus is a genus of fish from the family Poeciliidae. The species in the genus were formerly considered to be in the genus Heterandria but workers found that most of the species were not closely related to the type species of that genus, Heterandria formosa , and seven species were transferred to the genus Pseudoxiphophorus. [2] They are found in Central America. [3]

Species

The following seven species are classified as belonging to the genus: [3]

<span class="mw-page-title-main">Cyprinodontiformes</span> Order of fishes

Cyprinodontiformes is an order of ray-finned fish, comprising mostly small, freshwater fish. Many popular aquarium fish, such as killifish and live-bearers, are included. They are closely related to the Atheriniformes and are occasionally included with them. A colloquial term for the order as a whole is toothcarps, though they are not actually close relatives of the true carps – the latter belong to the superorder Ostariophysi, while the toothcarps are Acanthopterygii.

<span class="mw-page-title-main">Poeciliidae</span> Family of ray-finned fishes

Poeciliidae are a family of freshwater ray-finned fishes of the order Cyprinodontiformes, the tooth-carps, and include well-known live-bearing aquarium fish, such as the guppy, molly, platy, and swordtail. The original distribution of the family was the Southeastern United States to north of Río de la Plata, Argentina, and Africa, including Madagascar. Due to release of aquarium specimens and the widespread use of species of the genera Poecilia and Gambusia for mosquito control, though, poeciliids can today be found in all tropical and subtropical areas of the world. In addition, Poecilia and Gambusia specimens have been identified in hot springs pools as far north as Banff, Alberta.

<i>Gambusia</i> Genus of fishes

Gambusia is a large genus of viviparous fish in the family Poeciliidae. Gambusia contains over 40 species, most of which are principally found in freshwater habitats, though some species may also be found in brackish or saltwater habitats. The genus Gambusia comes from the Cuban term, "Gambusino", which means "free-lance miner". The type species is the Cuban gambusia, G. punctata. The greatest species richness is in Mexico, Texas, and the Greater Antilles, but species are also found elsewhere in the eastern and southern United States, the Bahamas, Central America, and Colombia. Gambusia species are often called topminnows, or simply gambusias; they are also known as mosquitofish, which, however, refers more specifically to two species, G. affinis and G. holbrooki, which are often introduced into ponds to eat mosquito larvae. As a consequence, they have been introduced widely outside their native range, and frequently become invasive, threatening local species. G. affinis and G. holbrooki are now established in many parts of the world and are likely to continue to spread as climatic conditions change. They are only occasionally kept in aquariums, due to their relative lack of color and the highly aggressive nature of the aforementioned mosquitofish species.

<i>Xiphophorus</i> Genus of fishes

Xiphophorus is a genus of euryhaline and freshwater fishes in the family Poeciliidae of order Cyprinodontiformes, native to Mexico and northern Central America. Xiphophorus species can be divided into 3 groups based on their evolutionary relationships: platyfish, northern swordtails, and southern swordtails. Platyfish formerly were classified in another genus, Platypoecilus, which is now obsolete. The type species is X. hellerii, the green swordtail. Like most other new world Poeciliids, platies and swordtails are live-bearers that use internal fertilization and give birth to live young instead of laying eggs like the bulk of the world's fishes. The name Xiphophorus derives from the Greek words ξίφος (dagger) and φόρος (bearer), referring to the gonopodium on the males. All are relatively small fishes, which reach a maximum length of 3.5–16 cm (1.4–6.3 in) depending on the exact species involved.

<i>Poecilia</i> Genus of fishes

Poecilia is a genus of fishes in the family Poeciliidae of the order Cyprinodontiformes. These livebearers are native to fresh, brackish and salt water in the Americas, and some species in the genus are euryhaline. A few have adapted to living in waters that contain high levels of toxic hydrogen sulfide and a population of P. mexicana lives in caves.

<i>Limia</i> Genus of fishes

Limia is a genus of livebearing fishes belonging to the Cyprinodontiform family Poeciliidae. It comprises 22 described species found in fresh, brackish, saltwater, and hypersaline habitats of the Greater Antilles islands in the Caribbean Sea. A vast majority are endemic to Hispaniola. There has been a long-running debate on whether Limia should be considered a subgenus of Poecilia rather than a full genus. Most Limia species are detrivores and herbivores. Due to their small size and coloring, they are sometimes kept in home aquaria.

George Sprague Myers was an American ichthyologist who spent most of his career at Stanford University. He served as the editor of Stanford Ichthyological Bulletin as well as president of the American Society of Ichthyologists and Herpetologists. Myers was also head of the Division of Fishes at the United States National Museum, and held a position as an ichthyologist for the United States Fish and Wildlife Service. He was also an advisor in fisheries and ichthyology to the Brazilian Government.

The Chiapas swordtail or upland swordtail is a species of livebearing freshwater fish of family Poeciliidae, and genus Xiphophorus. It is, therefore, in the same genus as the common platy and the swordtail. The Chiapas swordtail was discovered and first described by Donn E. Rosen in 1960, along with four other species of Xiphophorus.

<i>Heterandria</i> Genus of fishes

Heterandria is a genus of livebearing fishes within the family Poeciliidae. Most species occur in Guatemala and its surroundings, particularly Mexico, but the midget livebearer (H. formosa) comes from the southeastern United States.

<i>Leptolucania ommata</i> Species of fish

Leptolucania ommata, the Pygmy killifish, is a species of North American killifish found only in the southeastern United States. This fish is also found in the aquarium trade. This species grows to a length of 3 centimetres (1.2 in) TL. It is the only known member of its genus. The pygmy killifish was formally described by David Starr Jordan as Heterandria ommata in 1884, the type locality being given as Indian River, Florida.

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.

<i>Girardinus</i> Genus of fishes

Girardinus is a genus of poeciliids native to Cuba. The name of this genus honours the French zoologist Charles Frédéric Girard (1822-1895) for his work on the freshwater fish of North America.

<i>Phallichthys</i> Genus of fishes native to Central America

Phallichthys is a genus of poeciliids native to Central America. They are hardy fish which inhabit stagnant and slow-flowing waters, making them well-suited to fishkeeping.

Poeciliinae is a subfamily of killifish from the family Poeciliidae which contains species from the Americas which are collectively known as the livebearers because many, but not all, of the species within the subfamily are ovoviviparous.

Limia melanonotata, the blackbanded limia, is a toothcarp in the family Poeciliidae. It is endemic to the island of Hispaniola.

<span class="mw-page-title-main">Heterandriini</span> Tribe of fishes
