Spiriferidae from the Del Salto Formation, Calingasta-Uspallata Basin (Precordillera, Argentina) are described. The new genera Saltospirifer Cisterna & Archbold (with type species Saltospirifer guevarii Cisterna & Archbold sp. nov.) and Pericospira Archbold & Cisterna [with type species Spirifer (Spirifer) pericoensis Leanza 1945] are proposed. Punctothyris sanjuanensis (Lech & Acen? olaza 1990) is re-described and assigned to Pericospira. An Early Permian (Asselian) age is suggested for the two Argentinian species, agreeing with the age proposed previously.
