first record from Argentina:
Austrolebias patriciae Huber, 1995

type locality:
Paraguay, Departamento Presidente Hayes, route to Clorinda, 500 m S of Río Negro

distribution in Argentina:
Province of Chaco, Río Paraguay basin, temporary pools next to Ruta 11, 200 m from bridge over Río de Oro

In the description Huber mentioned a possible distribution for this species in Argentina. Although the recent paper of Calviño dates from July 2005 I hesitated for nearly one more year to list Austrolebias patriciae as a species from Argentinean freshwaters here in PecesCriollos, first because the author himself showed some uncertainty by using A. cf. patriciae and second he announced to deposit the animals, at that time alive in his aquaria, one day in the future in ichthyological collections. Meanwhile Jean Huber ( confirmed that at least the photos show animals that seem to be Austrolebias patriciae as described by him, and, more important, the results finally have been made reviewable as specimens have been deposited in the following collections (Calviño, MACN 8876, 5 males, 29.8-33.6 mm SL, MLP 9655, 3 males, 37.6-43.0 mm S.

The specimens come from temporary pools next to the Río de Oro, draining in lower Paraguay river in the province of Chaco, and represents the most austral registry until today for both species.
