Species

There are currently five recognized species in this genus. [2]

Taxonomy and systematics

This genus was formerly monotypic, featuring only P. leptocephalus, until it was expanded by the addition of the four species that made up the genus Tribolodon.

A leptocephalus is the flat and transparent larva of the eel, marine eels, and other members of the superorder Elopomorpha. This is one of the most diverse groups of teleosts, containing 801 species in 4 orders, 24 families, and 156 genera. This group is thought to have arisen in the Cretaceous period over 140 million years ago.

<i>Leptocephalus</i> (genus) Genus of fishes

Leptocephalus is a genus that was used for species of larval eels, called leptocephali, that were thought to be new fish species, or whose adult eel species were not known. Leptocephali differ so much in appearance from their adults that the larvae and adults of eels are not easily matched, and when first discovered, leptocephali were thought to be a distinct type of fishes, but not eels. Because of this, the genus designation of Leptocephalus was used for a while for unidentified leptocephali even after it was known that these were the larvae of eels thus becoming a "wastebasket taxon", but this practice is no longer used. Examples of marine congrid larvae, found in the western Indian Ocean and the Red Sea that were named this way are listed below. Only two species in two families are currently treated as having any validity, though the validity of L. bellottii is strongly in doubt.

<i>Pseudobarbus</i> Genus of fishes

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.

The big-scaled redfin, also known as the Japanese dace and ugui, is a medium-sized Asian fish. First described by Albert Günther in 1877 as Leuciscus hakonensis, it was the type specimen of the genus Tribolodon, having been described again as Tribolodon punctatum by Henri Émile Sauvage when he established that genus in 1883. It is the most widely distributed of the Pseudaspius species, found over much of the Sea of Japan. It is known to carry a number of parasites, including the trematode species Centrocestus armatus, and the copepod species Ergasilus fidiformis, which is carried in the fish's gills.
