Ixinandria steinbachi is the only species in the genus Ixinandria of catfish (order Siluriformes) of the family Loricariidae. [1]

Taxonomy

Ixinandria is part of the Rineloricaria group of the Loricariini tribe within the subfamily Loricariinae. [2] The phylogenetic position of Ixinandria within the tribe Loricariini remains uncertain. It has been suggested that Ixinandria could be synonym of Rineloricaria . [2]

Previously there were two species in this genus, but it was found that I. montebelloi was a synonym of I. steinbachi. [1]

Distribution

The distribution of Ixinandria includes rivers of the Atlantic slope of the Andes in Bolivia and Argentina. [2] I. steinbachi occurs in the Salado River basin. [3] I. steinbachi occurs in Salta Province in mountainous areas at high altitudes ranging from around 10002900 metres (33009500 ft) above sea level. [2]

Appearance and anatomy

Sexual dimorphism includes hypertrophied odontodes around the head margin and on the pectoral fin spines of mature males. [2] These fish reach a length of 11.3 centimetres (4.4 in) SL. [3]

Habitat ecology

I. steinbachi is a rheophilic species that lives in fast flowing and very oxygenated waters. Its color pattern reflects mimicry with stoned bottoms. [2] Fertilized eggs have been found on the hidden surface of a stone, suggesting that I. steinbachi could be a cavity spawner. [2]

Loricariidae is the largest family of catfish, with 92 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as "plecos", notably the suckermouth catfish, Hypostomus plecostomus, and are popular as aquarium fish.

<i>Rineloricaria</i> Genus of fishes

Rineloricaria is a genus of freshwater tropical catfish belonging to the family Loricariidae. They are commonly called whiptail catfish because of the long filament that grows out of the tip of the caudal fin that is characteristic of the genus. With the exception of R. altipinnis from Panama, they are native to the rivers of northern and central South America. Some species are regularly seen in the aquarium trade.

<i>Farlowella</i> Genus of fishes

Farlowella is a genus of fish in the family Loricariidae native to South America. This genus is broadly distributed in Amazon, Orinoco, Paraná and coastal rivers of the Guyana Shield. It is absent from the Pacific slope of the Andes and from the coastal rivers of the Brazilian Shield. Many of these species are kept in aquariums. This genus has a unique body shape that resembles a thin stick of wood. The body is slender and elongate, often with a pronounced rostrum and a brownish color with two lateral dark stripes beginning at the tip of the rostrum, passing over the eyes and ending at the tail, which are periodically interrupted on the caudal peduncle.
