Battling the un-dead: the status of the Diptera genus-group names originally proposed in Johann Wilhelm Meigen’s 1800 pamphlet Author Evenhuis, Neal L. Author Pape, Thomas text Zootaxa 2017 4275 1 1 74 journal article 32874 10.11646/zootaxa.4275.1.1 02308cb2-2ac2-407f-aa58-b7f5b657fc44 1175-5326 804234 065D531F-1095-4364-906B-EC55CFF9BFD4 22. Euphrosyne [ Euphrosyne ] Meigen, 1800: 16 . CURRENT STATUS: Unavailable name; work suppressed for the purposes of zoological nomenclature by action of I.C.Z.N. (1963: 339 [Opinion 678]); treated under Macrocera Meigen, 1803 [ teste Evenhuis (2006: 31) ]. [ Euphrosyne ] Osten Sacken, 1882: 193 . CURRENT STATUS: Unavailable name; criteria to make the name available not fulfilled in this work. REMARKS: Osten Sacken (1882) included this name only in a list of Meigen 1800 names without stating their availability. [ Euphrosyne ] Bezzi, 1907a: 56 . CURRENT STATUS: Unavailable name; criteria to make the name available not fulfilled in this work. REMARKS: Bezzi (1907a) included this name only in a list of Meigen 1800 names without stating their availability. Euphrosyne Meigen in Hendel , 1908 : 47 . ORIGINALLY INCLUDED SPECIES: None. FIRST INCLUDED SPECIES: Macrocera lutea Meigen, 1804 (in Coquillett 1910a: 542 ). TYPE SPECIES: Macrocera lutea Meigen, 1804 , by subsequent designation ( Coquillett 1910a: 542 ). CURRENT STATUS: Preoccupied by Euphrosyne Gray, 1866a ; Euphrosyne Buchecker, 1880 ; junior synonym of Macrocera Meigen, 1803 . New Synonymy . FAMILY: KEROPLATIDAE . REMARKS: Euphrosyne was originally proposed by Meigen (1800: 16) without included species and later made unavailable by the suppression of the entire work for the purposes of zoological nomenclature by action of the I.C.Z.N. (1963: 339 [Opinion 678]). Hendel (1908: 47) was the first after Meigen (1800) to give characters to differentiate the taxon (reproducing Meigen’s characters) and to treat Euphrosyne as valid, which makes the name available from that work with Meigen as author. Hendel’s (1908) single species, given as “ Tip. longicornis ?”, is questionably included and, as such, is not allowed under Article 67.2.5 of the ICZN Code . The first included species fulfilling the conditions of the Code was in Coquillett (1910a: 542) who selected Macrocera lutea Meigen, 1804 as type species by subsequent designation. Macrocera lutea Meigen, 1804 is currently treated in Macrocera Meigen, 1803 [ teste Evenhuis (2006: 31) ], which makes Euphrosyne Meigen in Hendel, 1908 a junior synonym of Macrocera Meigen, 1803 , n. syn .
