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 1000–2900 metres (3300–9500 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
Ixinandria 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]
