Lingulids and siphonotretids (Lingulata) are described from the Ordovician (Floian–Dapingian) Suri Formation of the Famatina Basin in western Argentina. This is the first record of lingulate brachiopods from the arc-related volcano-sedimentary rocks of the Famatina Range. The fauna includes the new obolids Famatinobolus cancellatum gen. et sp. nov. and Lithobolus limbatum sp. nov., and the new siphonotretid Chilcatreta lariojana sp. nov. Associated forms are the glosselins Glossella sp. and Rafanoglossa sp., the elkaniid Monobolina sp. nov., and an unnamed new genus of Lingulellotretidae. The biogeographical affinities of the described Famatinan lingulate assemblage are mixed, sharing Chilcatreta and Glossella with the Laurentian-derived Cuyania terrane, Lithobolus and Rafanoglossa with Bohemia, Monobolina with the Anglo-Welsh basin, and a new lingulellotretid with the Celtic assemblages of Wales.
