Taxonomic analysis of numerous specimens of the genera Iridistrophia and Eoschuchertella recovered from the Talacasto Formation (Lower Devonian), Argentine Precordillera, allows for the description of five new species:Iridistrophia and Eoschuchertella recovered from the Talacasto Formation (Lower Devonian), Argentine Precordillera, allows for the description of five new species: Iridistrophia prima n. sp., I. dominans n. sp., I. aliciae n. sp., I. magna n. sp. and Eoschuchertella delicata n. sp. The first one of the mentioned taxa is restricted to the basa1 levels of the formation (Lochkovian), and the remainder forms are typical from the upper part of the studied sequence (Pragian-lower Emsian). These new records of Iridistrophia extent bring a particular information on the origin of Devonian brachiopods faunas from the Argentine Precordillera.n. sp., I. dominans n. sp., I. aliciae n. sp., I. magna n. sp. and Eoschuchertella delicata n. sp.
