Titania

Evenhuis, Neal L. & Pape, Thomas, 2017, Battling the un-dead: the status of the Diptera genus-group names originally proposed in Johann Wilhelm Meigen’s 1800 pamphlet, Zootaxa 4275 (1), pp. 1-74 : 54

56. Titania

[ Titania ] Meigen, 1800: 35.

CURRENT STATUS: Name suppressed for the purposes of the Principle of Priority but not the Principle of Homonymy by action of I.C.Z.N. (1955a: 421 [Opinion 348]; treated under Chlorops Meigen, 1803 [teste Sabrosky (1999: 308)].

FAMILY: CHLOROPIDAE .

REMARKS: Titania Meigen (1800: 35) was declared an available name by two actions of the ICZN Commission (I.C.Z.N. 1910: 66 [Opinion 28], 1944: 181 [Opinion 152]). Later, in order to protect the younger name Chlorops Meigen, 1803 , the ICZN Commission (I.C.Z.N. 1955a: 421 [Opinion 348]) ruled to suppress Titania Meigen, 1800 for the purposes of the Principle of Priority but not for the Principle of Homonymy; treated under Chlorops Meigen, 1803 [teste Nartshuk (2012: 26)].

Titania Meigen in Hendel, 1908: 63 .

ORIGINALLY INCLUDED SPECIES: None.

FIRST INCLUDED SPECIES: Chlorops laeta Meigen, 1803 (in Coquillett 1910a: 615).

TYPE SPECIES: Chlorops laeta Meigen, 1803 , by subsequent designation ( Coquillett 1910a: 615).

CURRENT STATUS: Preoccupied by Titania Meigen, 1800 ; junior synonym of Chlorops Meigen, 1803 . New Synonymy.

REMARKS: Titania was originally proposed by Meigen (1800: 35) without included species, the entire work of which was subsequently suppressed for the purposes of zoological nomenclature by action of the I.C.Z.N. (1963: 339 [Opinion 678]). Hendel (1908: 63) was the first after Meigen (1800) to give characters to differentiate the taxon (reproducing Meigen’s characters) and to treat Titania as valid, which makes the name available from that work with Meigen as author. No species were included in Hendel (1908). The first included species is in Coquillett (1910a: 615), who designated Chlorops laeta Meigen, 1803 as the type species. The action of the I.C.Z.N. (1955a: 421 (Opinion 348) suppressed Titania only for the purpose of priority and not for homonymy. As there is no wording in Opinion 678 to contravene earlier rulings of names in Meigen (1800), this allows for Titania to be made available by subsequent usage as a valid taxon, but the name immediately becomes invalid as a junior homonym of Titania Meigen, 1800 .
