Tabanidae This worldwide family of Orthorrhapha flies contains almost 4,500 species (Marshall 2012, Evenhuis & Pape 2020). Rondani (1848b, 1850 c, 1851, 1863, 1868b, 1873f, 1875c) described 19 Neotropical, 13 Oriental, two Nearctic and one Palaearctic nominal species: 17 are currently considered as valid and 18 are synonyms (Fairchild 1971, Stone 1975, Wilkerson & Fairchild 1983, Chvála 1988, Coscarón & Papavero 2009). Rondani (1850 c, 1863) proposed two new replacement names and one substitute name for nominal species previously described and named by other authors. Philip (1965a), Coscarón & Philip (1967) examined the MZUN and MZUF Neotropical material without publishing any lectotype designation. Ricardo (1911) examined the MSNG type material without publishing any lectotype designation. Here, we designate a lectotype for Chrysops alter Rondani, 1875, Chrysops unizonatus Rondani, 1875, Tabanus dives Rondani, 1875, Tabanus fulvissimus Rondani, 1875, Tabanus ignobilis Rondani, 1875, Tabanus justorius Rondani, 1875. O’Hara et al. (2011: 213) incorrectly attributed two species to Rondani. Costa (1866: 39) listed one unpublished Rondani name (nomen nudum). Except for the type material of two South American species, which has been destroyed (Fairchild 1971, Leonardi et al. 1995, Mazzotti 2011), the type material has been recovered for all nominal species and is distributed among the MSNG (14), MZUF (11), MZUN (ten) and MRSN (two).
