Otocinclus flexilis is not a species from Argentina

distribution of Otocinclus arnoldi + Otocinclus flexilis
Geographic distribution of Otocinclus arnoldi (red squares) and O. flexilis (black dots).
(modified map from publication)

Not a species from Argentina:
Otocinclus flexilis Cope,1894

remarks:
Lehmann (2006) limits the distribution of Otocinclus flexilis to tributaries of the Patos lagoon system and resurrects O. arnoldi from the synonymy with O. flexilis. Records of Otocinclus flexilis from Argentina are now to be considered Otocinclus arnoldi.

abstract (from publication):
Otocinclus arnoldi from the La Plata basin is resurrected from the synonymy of O. flexilis described from rio Jacuí basin, based on two diagnostic characters: the presence of five branched pectoral-fin rays vs six in O. flexilis, and the presence of the raised tuft of enlarged odontodes at the tip of the supraoccipital posterior process, in juvenile as well as in adults of O. arnoldi...

distribution (from publication):
Otocinclus flexilis is restricted to the laguna dos Patos drainage basin.
