Ixinandria steinbachi • Loricariidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Ixinandria steinbachi** (Regan, 1906)
Common Name(s)	None
Type Locality	Departamento Cachi, 25°06'15''S, 66°11'16''W, río Juramento basin, Salta, Argentina, elevation 2500 meters.
Synonym(s)	Canthopomus montebelloi, Ixinandria montebelloi, Loricaria steinbachi
Species Information
Size	113mm (4.4") SL. Find near, nearer or same sized spp.
Identification	According to Rodriguez et al (2008), Ixinandria is most similar to Rineloricaria and can be distinguished from most genera by the total lack of abdominal plates, including the preanal plate. Hartiella and a few species of Harttia also have the abdomen completely devoid of plates, and can be distinguished from Ixinandria by having 12 branched caudal-fin rays (vs. 10 in Ixinandria) and by the absence of postorbital notch, which is present in Ixinandria.
Sexing	Rodriguez et al noted that "Males with head wide and flattened; long hypertrophied odontodes on sides of head and on upper side of branched pectoral-fin rays; short odontodes on remaining of dorsal surface of body, especially on predorsal region; unbranched pectoral-fin ray hypertrophied."
General Remarks	In their 2008 review of the genus, Rodriguez et al determined that the populations I. montebelloi and I. steinbachi were not significantly distinct and did not deserve separate species recognition. As such, they placed I. montebelloi in synonymy of I. steinbachi.
Habitat Information
Distribution	South America: Upper río Juramento basin, río Salado drainage in Salta (Argentina), upper río Bermejo in northwestern Argentina and southern Bolivia, and upper río Pilcomayo in southern Bolivia.

Other Parameters	This species lives in fast flowing and highly oxygenated waters, with stony bottom, usually hiding under the stones during the day.
