Background: The tribe has received little attention in Argentina. Dellapé (2014) recorded nine genera and 15 species from this country. Results: A comprehensive study of the Lethaeini (Heteroptera, Rhyparochromidae) from Argentina is presented. Herein three new species of Cryphula Stål, one new species of Cistalia Stål, and the male of Cryphula australis Berg are described. The genus Petissius Distant and the species Cistalia binotata Slater & Baranowski, C. neotropicalis Slater & Baranowski, and Petissius spinipes Stål are reported for the first time from Argentina; also the known distribution is extended for many of the previously recorded species. A generic key, keys to species, and distributional maps to the Argentinean species are also given. Dorsal habitus photographs of all species and male and female genitalia of the new species are provided to facilitate identification. Conclusion: The Lethaeini fauna from Argentina is increased to 10 genera and 22 species. The distribution of the tribe in the country is mainly Neotropical into the Chacoan subregion, with most of the species distributed on the Chacoan and Pampean provinces (Chacoan Domain) and Parana Forest Province (Parana Domain). Only Rhaptus quadricollis appears to be an Andean element, with most of the known records in the South American Transition Zone (Monte Province).
