Isoneuromyia semirufa (Meigen, 1818)

( Figs 20–25 )

Material examined. CZECH REPUBLIC: BOHEMIA: Jizerské hory Mts.,several localities (see ŠEVČÍK &VONIČKA 2008); Krkonoše Mts., Kotelní jámy, 30.vii.2008, 3 ♂♂, M.Barták leg.(Malaise trap). MORAVIA: Moravskoslezské Beskydy Mts. , Černá Ostravice, 24.viii.2016, 1 ♂ ; Hrubý Jeseník Mts., Rejvíz , 57 ♂♂ 12 ♀♀, 2.vii.–28.ix.2005, J. Roháček & J. Ševčík leg.(Malaise traps), J. Ševčík det. ( JSL-UOC) .

Comments. A widely distributed European species. It may have been confused in the collections with the very similar I. czernyi . In the Czech and Slovak Republics, this species has mostly been found in mountains, being relatively common in Malaise trap samples from spruce forests and peat-bogs (e.g. ŠEVČÍK & VONIČKA 2008).

However, the question of the identity of I. semirufa remains still open, because MORGE (1975) illustrated under this name a slightly different form, with a mostly reddish abdomen. Similarly, a form with orange thorax and three dark lateral stripes on scutum, corresponding to I. czernyi , was illustrated under the name I. signata (Meigen, 1818) , which poses a question over their possible synonymy and validity of the latter name. These questions could be definitely solved after examination of the relevant types in the Meigen’s collection and after their association with recent material, suitable for DNA extraction.
