The Simuliidae fauna from the Santa Catarina state, Brazil, was documented, based primarily on specimens deposited in the collections of the Instituto Oswaldo Cruz, Brazil and the La Plata Museum, Argentina. The results of our survey are organized by mesoregion and by municipality. Of the 51 municipalities where black flies were recorded, 46 represented new unpublished locality records. A total of 29 species belonging to two genera and eight subgenera were found, among which five are new records for the Santa Catarina state. The species recorded are (new records are marked with a *): Lutzsimulium hirticosta, Simuliium (Chirostilbia) acarayense, S. (Chirostilbia) distinctum, S. (Chirostilbia) empascae, S.
