Primeros registros documentados de la mojarra Cheirodon ibicuhiensis Eigenmann, 1915 (Characiformes, Cheirodontinae) para la Provincia de Córdoba, Argentina

In this work, the presence of Cheirodon ibicuhiensis is reported for the first time in the Primero River basin (Suquia) in the province of Cordoba, Argentina. This species had been previously reported in Argentina for the median and lower sections of the Uruguay and Parana rivers. However, these new records of C. ibicuhiensis for the province of Cordoba extend its distribution to other basins outside of the east region of Argentina. The species have been observed in the Sierras Chicas region in the last decade, in four rivers: Chorrillos, Toro Muerto, Yuspe and Suquia. Morphometric measurements of nine specimens of this species and environmental parameters of the habitat where it was collected are also provided. Probably, C. ibicuhiensis was introduced into this river in order to have specimens for live-bait for fishing. It has always been observed forming shoals with other native mojarras of the province.
