Genus Loewia Egger

Thrychogena Rondani, 1856: 65 . Nomen oblitum (see O’Hara et al. 2011: 180); senior but invalid synonym of Loewia Egger, 1856 . Type species: Thrychogena brevifrons Rondani, 1856, by monotypy.

Loewia Egger, 1856: 386 . Nomen protectum (see O’Hara et al. 2011: 180); junior but valid synonym of Thrychogena Rondani, 1856 . Type species: Loewia setibarba Egger, 1856, by monotypy.

Thricogena Rondani, 1859: 242 . Unjustified emendation of Thrychogena Rondani, 1856 . This is one of two original spellings of the name in Rondani (1859), the other being Tricogena . Acting as the First Reviser, O’Hara et al. (2011: 179) selected Thricogena as the correct original spelling.

Fortisia Rondani, 1861: 94 . Type species: hereby fixed under Article 70.3.2 of ICZN (1999) as Loewia nudigena Mesnil, 1973, misidentified as Tachina foeda Meigen, 1824 (as “ F. Phaeda Wdm. Mgn. (non Macq.)”) in the fixation by monotypy of Rondani (1861).

Thrichogena Bezzi, 1894: 305 (in synonymy with Loewia Egger, 1856), 352 (index). Unjustified emendation of Thrychogena Rondani, 1856 (see O’Hara et al. 2011: 268).

Oestroloewia Mesnil, 1953: 152 . Type species: Oestroloewia crassipes Mesnil, 1953, by monotypy.

Thrychogrna. Incorrect subsequent spelling of Thrychogena Rondani, 1856 . This spelling first appeared in the Junk 1914 facsimile edition of Rondani (1856) and was unwittingly attributed to the original Rondani (1856) by Herting (1984: 109, 190) (see O’Hara et al. 2011: 201).

Trichogena . Incorrect subsequent spelling of Thrychogena Rondani, 1856 (Bezzi & Stein 1907: 403, in synonymy with Loewia; Mesnil 1973: 1204, in synonymy with Loewia, p. 1205, as subgenus of Loewia; Herting 1984: 109).

Tricogena . Incorrect original spelling of Thricogena Rondani, 1859 (Rondani 1859: 84, as “ Tricogenae ” in Latin) (see O’Hara et al. 2011: 183).
