Taxonomy of Ixinandria IsbrÃ¼cker & Nijssen (Loricariidae: Loricariinae) based on morphological and molecular data

MÃ³nica S. Rodriguez, Christian A. Cramer, Sandro L. Bonatto and Roberto E. Reis

The genus Ixinandria was described in 1979 to include I. steinbachi from the upper rÃ*o Juramento in northern Argentina and I. montebelloi from the upper rÃ*o Bermejo in southern Bolivia. We used a multivariate morphometric analysis (Principal Components Analysis) and a molecular comparison of the Cytochrome Oxidase I gene to investigate variation among distinct populations from the known distribution range of both species. We onclude that the populations are not significantly distinct and do not deserve separate species recognition, and we place I. montebelloi in the synonymy of I. steinbachi.
