Tromera Swinderen, 1822: 87 .
TYPE SPECIES: Madiza glabra Fallén, 1820, by monotypy .
CURRENT STATUS: junior synonym of Madiza Fallén, 1810, n. syn.
FAMILY: MILICHIIDAE .
REMARKS: Swinderen’s descriptive word for the genus-group name as “Angstige” [= anxious; quivering] can be considered a behavioral trait and thus makes the generic name available. Additionally, the only included species ( glabra) is determined here as Madiza glabra Fallén, 1820 [since it is the only species of acalyptrate flies with the specific name glabra that was described at that time], which can be unambiguously assigned to a nominal speciesgroup taxon makes the genus name available (Code Art. 12.2.5). Madiza glabra Fallén, 1820 is the type species of the milichiid genus Madiza Fallén, 1810 [teste I.C.Z.N. 1978: 109 [Opinion 1112]), thus, I here treat Tromera Swinderen, 1822 as a junior synonym of Madiza Fallén, 1810, n. syn.
