Abstract

BOGAN, Sergio  and  CARDOSO, Yamila P. Revisión de la distribución de Glanidium ribeiroi Haseman, 1911 en la Argentina (Siluriformes: Auchenipteridae). Rev. Mus. Argent. Cienc. Nat. [online]. 2017, vol.19, n.1, pp.1-7. ISSN 1853-0400.

Glanidium ribeiroi was described from the Iguazú River basin in Paraná State, Brazil. In Argentina, the species was reported for the Urugua-í stream and the Iguazú River basins in the Misiones province, and some tributaries of the middle Paraná River basin, such as Cuña Pirú in Misiones and the Salado River at Santa Fe province. After a critical review of all the Argentinian records of Glanidium ribeiroi we concluded that the specimens reported from Cuñá Pirú should be referred to Tatia neivai (Ihering, 1930) and the record of G. ribeiroi from Santa Fe province was based on a specimen that is here assigned to Microglanis carlae Vera Alcaraz, da Graça & Shibatta, 2008. In this way, the southernmost records for G. ribeiroi are to be excluded and the endemic nature of this species is confirmed for the Urugua-í and Iguazú basins.
