Taxonomy

The type species of this genus, P. eigenmanni, was first described in 1946 under the genus Pimelodus . In 2002, the genus Propimelodus was described for this species. [1] Shortly after, in 2006, the species P. caesius was described to this genus and in 2007 another new species, P. araguayae was described. Other species will be described in the future. [2]

Propimelodus is classified under the " Calophysus-Pimelodus clade". Within this clade, it is considered a part of the "Pimelodus-group" of Pimelodids, which also includes Pimelodus, Exallodontus , Duopalatinus , Cheirocerus , Iheringichthys , Bergiaria , Bagropsis , Parapimelodus , Platysilurus , and Platystomatichthys . [1]

Species

There are currently three recognized species in this genus: [3]

Distribution

P. eigenmanni originate from the lower Amazon River as well as large tributaries such as the Xingu, Trombetas, Jari River, and lower Madeira River in Brazil, and the rivers Kourou and Oyapock in French Guiana. [1] P. caesius has the largest range of the genus. [4] P. caesius is also found in many of these regions, with tributary range including Tocantins, Pará, Jari, Xingu, Trombetas, Madeira, Negro, Purús, Japurá, Juruá, and Içá rivers. [2] P. araguayae is only known from the middle Araguaia River. [4]

Appearance and anatomy

These fish have three pairs of barbels. As in other pimelodids, these whiskers are extremely long; the maxillary barbels extend past the base of the caudal fin. Propimelodus species have a rather long adipose fin. [1] Unlike its congeners, P. araguayae has a black spot on its dorsal fin. [4]

P. eigenmanni grows not much longer than 20 centimetres (8 in). [1] P. eigenmanni is a pale blue-gray to tan. [1] P. caesius also has an attractive blue coloration. [2]

Ecology

Propimelodus lives in swiftly flowing waters of open channels of the Amazon River and many of its large tributaries; P. caesius is one of the most common fish in these habitats. [2]

P. eigenmanni associate with mud or detritus substrates. [1] P. caesius is found in turbid, blackwater habitats over sand, clay, and detritus substrates. [2] P. eigenmanni is nocturnal, found in tidally influenced freshwater habitats on mud substrate and near dense vegetation. [1] P. araguayae has been found near the edge of rivers among macrophytes.

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

Catfish are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores, and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby. Many catfish are nocturnal, but others are crepuscular or diurnal.

<span class="mw-page-title-main">Redtail catfish</span> Species of fish

The redtail catfish, Phractocephalus hemioliopterus, is a pimelodid (long-whiskered) catfish. In Venezuela, it is known as cajaro, and in Brazil, it is known as pirarara, stemming from the Tupi language words pirá and arara. It is the only extant species of the genus Phractocephalus. This fish is common in the aquarium trade, although its massive adult size makes it unsuitable for all but the largest aquariums. They feed on fish, crustaceans and fallen fruits. They are not evaluated by IUCN.

<i>Aspidoras</i> Genus of fishes

Aspidoras is a genus of catfishes of the family Callichthyidae from Brazil.

The Chiapas catfish, Lacantunia enigmatica, is an unusual species of catfish from the Usumacinta River basin in the Mexican state of Chiapas and in Guatemala. It was scientifically described in 2005 and placed in its own family Lacantuniidae. While discovery of an undescribed species of catfish is not uncommon, discovery of a new family of any vertebrate group is a rare event. The Chiapas catfish mainly feeds on crabs, prawns, small fish, and large, tough plant seeds. This catfish is commonly fished in its natural habitat, where it is known as madre de juil, which means "mother of Rhamdia".

<i>Baryancistrus</i> Genus of fishes

Baryancistrus is a genus of freshwater Loricariid catfish. They inhabit flowing sections of rivers, especially clearwater, in the basins of the Amazon and Orinoco in Brazil and Venezuela. The largest species reach up to 34 cm (13 in) in total length.

<i>Sorubim</i> Genus of fishes

Sorubim is a small genus of long-whiskered catfish native to tropical South America. A number of characteristics allows the differentiation of each species in the genus. Sorubim species are important food fish in South America and are highly significant to fisheries of some areas; however, harvests of these fish are not identified as much as other, more popular food fishes such as Colossoma, Arapaima, and Brachyplatystoma. Some species of this family are popular aquarium fish.

<span class="mw-page-title-main">Heptapteridae</span> Family of fishes

The Heptapteridae, or three-barbeled catfishes, are a family of catfish that originate from the Americas. Most species are restricted to South America, but Imparfinis lineatus, Nemuroglanis panamensis and Pimelodella chagresi are native to Panama, and Rhamdia species occur as far north as Mexico. The name Heptapteridae is derived from Greek, hepta meaning seven and pteron meaning fin.

<i>Brachyplatystoma</i> Genus of fishes

Brachyplatystoma is a genus of catfish from the family Pimelodidae. As the occasionally used common name goliath catfishes indicates, this genus includes some of the largest species of catfish, including the piraíba, B. filamentosum, which reaches up to the region of 3.6 metres (12 ft) in length. Brachyplatystoma are found in the Amazon and Orinoco basins, and other tropical freshwater and brackish habitats in South America. Some species are migratory. These fish are important as food fish and, to some extent, aquarium fish.

<i>Platystomatichthys</i> Genus of fishes

Platystomatichthys sturio is the only species in the genus Platystomatichthys of the catfish family Pimelodidae. It is sometimes called the sturgeon catfish.
