TYPE LOCALITY: “ Venezuela ” . TYPE MATERIAL: 1 ♀ , syntype ( MRSN : Box 1755): Tabanus L. nigrocaeruleus Rndn. , ♀ , Venezuela / Tabanus nigrocaeruleus Rond. 1850: 191 , Venezuela (not original label); 1 ♀ , syntype (slightly covered with mold) ( MZUN : Box Coll. entomol. extra-europea, Fam. Tabanidei - Gen. Pangonia a Corizoneura ): Dicladocera nigrocoerulea Rnd. , Venezuela / M. Zool. N° 10909 / Probable type of D. nigrocoerulea Rond. , ♂ , G.B. Fairchild, 1964. CURRENT STATUS: valid species (as “ Dicladocera nigrocoerulea ”) ( Fairchild 1971: 74 , Coscarón & Papavero 2009: 90 ). REMARKS: Rondani (1850c: 191) described Tabanus nigrocaeruleus from just the female sex, without specifying the exact number of specimens and not giving a range of lengths, from material received from E. Truqui. Costa (1866: 39) listed a single MZUN specimen numbered “908”. The subsequent spelling “ nigrocoeruleus ” has been used ( Philip 1965a: 121 , Fairchild 1971: 74 , Coscarón & Papavero 2009: 90 ) but it is not in prevailing usage ( Hunter 1901: 142 , Kertész 1908: 265 , O’Hara et al. 2011: 212 ). Therefore, the original spelling “ nigrocaeruleus ” is to be used and “ nigrocoeruleus ” is an incorrect subsequent spelling. Philip (1965a: 121) and Fairchild (1971: 74) reported syntypes in the MZUN and MRSN. We also found one syntype in the MRSN and one in the MZUN.
