Among ectoparasites sampled from bats during diversity surveys in 2005 and 2008 in northern Argentina there were specimens of Paradyschiria parvula Falcoz, 1931 (Diptera, Streblidae) and Hesperoctenes vicinus Jordan, 1922 (Hemiptera, Polyctenidae) that represent first records for Argentina and Salta province, respectively. New ectoparasite-host associations and additional distributional records of ectoparasites were also recorded and are given for Jujuy and Salta provinces.
