The Diptera genus-group names of Camillo Rondani are reviewed and annotated. A total of 601 nomenclaturally available genus-group names in 82 families of Diptera are listed alphabetically. For each name the following are given: author, year and page of original publication, originally included species [and first included species if none were originally included], type species and method of fixation, current status of the name, family placement, and a list of any emendations of it that have been found in the literature. Remarks are given to clarify nomenclatural or taxonomic information. In addition, an index is provided to all the species-group names of Diptera proposed by Rondani (1,236, of which 1,183 are available) with bibliographic reference to each original citation. Appended to this study is a full bibliography of Rondani's works and a list with explanations for all new synonymies arising from revised emendations.
