A taxonomic revision of Cheilanthes from South America and a phylogenetic analysis of the genus, based in morphological and molecular data, including a representative amount of species from South Cone, are presented. In the phylogenetic study, the polyphyly of Cheilanthes was corrobrated and new groups for South American species were proposed. The taxonomic treatment included diagnostic descriptions and a key to determinate 44 species. Two new combinations, Cheilanthes solitaria (R. M. Tryon) Ponce and Adiantopsis flexuosa (Kunze) Ponce & Scataglini, were established; likewise C. regularis Kunze ex Mett. was recognized within Adiantopsis. Also identity of unclear taxa was resolved and updated synonyms were given, performing lectotypifications in Notholaenarufa var. minor  C. Presl; Notholaena rufa var. major  C. Presl; Cheilanthes fraseri  Mett. ex Kuhn; Acrostichum glaucum Cav.; Cheilanthes hieronymi Herter; Cheilanthes marginata var. gracilis Hieron.; Cheilanthes thellungii Herter; Cheilanthes pohliana Kunze ex Mett. and Cheilanthes flexuosa Kunze.
