Polietes Rondani , 1866a : 71 , 91 . ORIGINALLY INCLUDED SPECIES: Musca lardaria Fabricius, 1781 . TYPE SPECIES : Musca lardaria Fabricius, 1781 , by original designation . CURRENT STATUS: Valid genus [ teste Pont (1986b: 85) ]. FAMILY: MUSCIDAE . 456 . Polionoma Rondani , 1856 : 107 . ORIGINALLY INCLUDED SPECIES: None. FIRST INCLUDED SPECIES: Sapromyza obsoleta Fallén, 1820 (in Coquillett, 1910: 593 ). TYPE SPECIES : Sapromyza obsoleta Fallén, 1820 , by subsequent designation ( Coquillett, 1910: 593 ) . CURRENT STATUS: Junior synonym of Sapromyza Fallén, 1810 [ teste Rondani (1868b: 36 ; 1868c: 234 )]. FAMILY: LAUXANIIDAE . REMARKS: Originally proposed in Rondani (1856) without included species. Although placed by Rondani (1868b: 36 ; 1868c: 234 ) in synonymy with Sapromyza , no species were expressly included for Polionoma there. Coquillett (1910: 593) is interpreted here as the first to expressly include a species ( Sapromyza obsoleta Fallén, 1820 ), and he designated it as the type of Polionoma Rondani, 1856 . The name has not been treated in any of the regional Diptera catalogs so we follow Rondani (1868c , d) in treating Polionoma Rondani, 1856 as a junior synonym of Sapromyza Fallén, 1810 . [Polyetes] Rondani , 1877c : 302 . CURRENT STATUS: Incorrect subsequent spelling of Polietes Rondani, 1866 . FAMILY: MUSCIDAE . REMARKS: Criteria for making this name available as an emendation were not found to be fulfilled in this work. [Porphirops] Rondani , 1856 : 142 , 145 , 220 . CURRENT STATUS: Incorrect subsequent spelling of Porphyrops Meigen, 1824 . FAMILY: DOLICHOPODIDAE . REMARKS: The earliest mention of Porphyrops Meigen, 1824 using the spelling “ Porphirops ” that we have found in this study is in Macquart (1834a : “explication des planches”, page 7). Porphirops would be eligible as an unjustified emendation in Macquart (1834a) by virtue of similar spelling changes in two or more names from “y” to “i” in the same work, but as Macquart (1834a: 434) also used the original spelling Porphyrops , his treatment of the name is ambiguous. We thus follow ICZN Code Article 33.5 in treating this spelling as an incorrect subsequent spelling. Porphyrops Meigen, 1824 is an objective senior synonym of Argyra Macquart, 1834 . However, due to prevailing usage, Argyra is retained here for stability following Dyte & Smith (1980: 458) . An application to the ICZN Commission is warranted to either suppress Porphyrops Meigen, 1824 and conserve Argyra Macquart, 1834 or to deem reversed synonymy when these genus-group names are considered synonyms of each other.
