TYPE LOCALITY: “ Parisiis [ Paris ]” ( Fabricius, 1794: 284 ) [ type locality for Phasia crassipennis ( Fabricius, 1794 ) ]. TYPE MATERIAL: see Remarks. CURRENT STATUS: junior synonym of Ectophasia crassipennis ( Fabricius, 1794 ) ( Herting & Dely-Draskovits 1993: 402 ) . REMARKS: Rondani (1843a: 461) considered the males of Phasia crassipennis ( Fabricius, 1794 ) and the females of Phasia analis (Fabricius, 1798) as belonging to the same species but, instead of applying the Principle of Priority, incorrectly proposed the substitute name Phasia dispar . He reaffirmed having proposed Phasia dispar to combine the males of Phasia crassipennis , Phasia discoidea Meigen, 1838 and Phasia varia Meigen, 1838 and the females of Phasia analis ( Rondani 1861b: 219 , 1862d: 37 ). He later ( Rondani 1865c: 225 ) treated Phasia dispar as a valid species. Phasia dispar is considered as a synonym of Phasia crassipennis by Bezzi & Stein (1907: 574) and Herting & Dely-Draskovits (1993: 402) , and as a synonym of Phasia analis by Schiner (1861a: 399 , 1864: 101 ), but never as a valid species. O’Hara et al. (2011: 208) considered the name Phasia dispar as available. The type material for Phasia dispar will be the same as for the name it was proposed to replace, i. e., Phasia crassipennis . There are four syntypes of this latter species in the ZMUC ( O’Hara et al . 2009: 133 ). Under the name Phasia dispar there are one male and one female in the MSNC and two specimens in the MZUB (all non-types).
