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 Script error: No such module "convert". 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]
