Trepidaria Swinderen, 1822: 87 .

TYPE SPECIES: Musca vibrans Linnaeus, 1758 , by monotypy .

CURRENT STATUS: junior synonym of Seioptera Kirby & Spence, 1817 , n. syn.

FAMILY: ULIDIIDAE .

REMARKS: Swinderen’s descriptive words after the generic name “de Bevenden” [= the trembler] are enough to make the generic name available. Additionally, the only included species ( vibrans ), determined here as Musca vibrans Linnaeus, 1758 , that can be unambiguously assigned to a nominal species-group taxon makes the name available (ICZN Code Art. 12.2.5). Musca vibrans Linnaeus, 1758 is currently treated in the ulidiid genus Seioptera Kirby & Spence, 1817 [teste Kameneva & Korneyev (2006)], which makes Trepidaria Swinderen, 1822 a junior synonym of it [teste Evenhuis & Pape (2019: 112)]. Trepidaria was originally proposed by Meigen (1800: 35) without included species and later made unavailable by the suppression of the work for the purposes of zoological nomenclature by action of I.C.Z.N. (1963: 339 [Opinion 678]). Hendel’s (1908:63) first inclusion of a species ( Musca petronella Linnaeus, 1758 ) and characters by Meigen made the name available there, and fixed the generic concept by monotypy. Evenhuis & Pape (2019: 112) treated Trepidaria Meigen in Hendel, 1908 as a junior synonym of Calobata Meigen, 1803 in Micropezidae , a separate generic name from Trepidaria Swinderen, 1822 in Ulidiidae and noted the homonymy of the two.
