We present a new record for Austrolebiaselongatus from Gualeguaychú, in Entre Ríos province,Argentina, based on new fieldwork and a revision of materialdeposited in national ichthyological collections.We also give evidence on the erroneous records of Austrolebiasmonstrosus and A. vandenbergi from Ituzaingó,Corrientes province, as well as present additional recordsfrom Salta province for those species. Materialpreviously determined as A. elongatus from Santiagodel Estero is attributed to A. monstrosus. We restrict thedistribution of these two species to Semi-arid Chaco Regionin Argentina, Paraguay and Bolivia.
