Astyanax taeniatus (Jenyns, 1842)

original Tetragonopterus taeniatus

type locality Socego , Rio de Janeiro state, Brazil

López et al. (2003) assigned the first record of this species to Géry (1978) from the South of Buenos Aires province. Géry actually only informed about the fact that Lueling had found A. taeniatus in a laguna near Guaminí. In 1981 Lueling himself published a report about the collection he had conducted in late 1975 in the lakes of Guaminí, known as the Lagunas Encadenas del Oeste.

He provided a photo ( fig. 3 ) of a specimen he had determined as A. taeniatus , but no further details or data. The only members of the genus subsequently reported on from localities South of the río Salado basin are Astyanax eigenmanniorum (e.g. Almirón et al. 1997, Casciotta et al. 1999) and A. pampa ( Casciotta et al. 2005, Fulvio Pérez 2008). Miquelarena & López (1995) conducted another ichthyological inventory of the Lagunas Encadenadas del Oeste and recorded A. cf. eigenmanniorum , but explicitely stated that they could not confirm the presence of A. taeniatus . Buckup (2003) restricted the distribution of A. taeniatus to the “ Paraíba do Sul River drainage and coastal rivers of Rio de Janeiro and Espírito Santo States” in Brazil.

Combining the above given information and despite the fact that so far we had no opportunity to examine Lueling’s voucher material, if still available, we tentatively remove Astyanax taeniatus from the faunal list of freshwater fishes found in Argentina.
