REMARKS: Rondani (1875c: 457) described Tabanus dives from just the female sex, without specifying the exact number of specimens and not giving a range of lengths, from material collected by G. Doria and O. Beccari. Ricardo (1911: 186; 207) reported that the type series consists of two females in the MSNG (instead of three), but did not mention another three females in the MZUF, which bring the original type series to six specimens. Guiglia (1957: 197) reported a “ holotype ” in the MSNG. In his original description Rondani did not explicitly refer to a single specimen, therefore Guiglia’s “ holotype ” specimen must be considered as the lectotype (I.C.Z.N. 1999: Article 74.6). Raineri & Rey (1996: 54) reported just one specimen in the MSNG. The additional specimens not examined by Ricardo or Guiglia (two females in the MSNG and the three females in the MZUF) are paralectotypes.
