We present here the first record of Histiotus velatus I. Geoffroy St.-Hilaire, 1824 for the province of Salta, Argentina. Until now, in Argentina, this species was only known from Jujuy, Corrientes, and Misiones provinces. Our record adds a fourth province to the distribution of this species in the country and the second record for the Northwestern Argentina, rising to 39 the number of bat species in Salta. We captured three adult males with mist-nets placed in Parque Nacional El Rey. This site represents one of the last largest continuous blocks of protected forests, within a region affected by the greatest anthropic transformation (e.g. agricultural development, cattle grazing) of northwestern Argentina.
