Resumen:
Abstract. A new species of afghanodesmatid, Cardiolaria benicioi, is recorded from Sandbian strata of northwestern Argentina. This species confirms the strong paleobiogeographic relationships between the northwestern Argentina basin and West Gondwana area. The Mid-Late Ordovician distribution of bivalves fit well into the Mediterranean Province defined upon brachiopod and trilobite faunas. The similarities between Tremadocian and Floian bivalves from the northwestern Argentina and Western Gondwana indicate that such Mediterranean paleobiogeographic pattern can be traced back well into the Early Ordovician.
