Rineloricaria steinbachi is a species of freshwater ray-finned fish belonging to the family Loricariidae, the mailed catfishes, and the subfamily Loricariinae, the suckermouth armored catfishes.[2] This species is sometimes in the monospecific genus Ixinandria.[3] R. steinbachi is found in central South America in Argentina and Bolivia.
Taxonomy
Ixinandria was part of the Rineloricaria group of the Loricariini tribe within the subfamily Loricariinae.[4] The phylogenetic position of Ixinandria within the tribe Loricariini remains uncertain. It has been suggested that Ixinandria could be synonym of Rineloricaria.[4]
Previously there were two species in this genus, but it was found that Ixinandria montebelloi was a synonym of R. steinbachi.[3]
Distribution
The distribution of this species includes rivers of the Atlantic slope of the Andes in Bolivia and Argentina.[4] R. steinbachi occurs in the Salado River basin.[5] R. steinbachi occurs in Salta Province in mountainous areas at high altitudes ranging from around 1,000–2,900 metres (3,300–9,500 ft) above sea level.[4]
Appearance and anatomy
Sexual dimorphism includes hypertrophied odontodes around the head margin and on the pectoral fin spines of mature males.[4] These fish reach a length of 11.3 centimetres (4.4 in) SL.[5]
Habitat ecology
Rineloricaria steinbachi is a rheophilic species that lives in fast flowing and very oxygenated waters. Its color pattern reflects mimicry with stoned bottoms.[4] Fertilized eggs have been found on the hidden surface of a stone, suggesting that R. steinbachi could be a cavity spawner.[4]
