I expect this one to be Minettia longipennis, but need confirmation because I red in older threads that there could have other similar species.
Is it case in France ?

Hi Stephane.
According Shatalkin's key for Palearctic Lauxaniidae (2000) the only another possibility is M.martineki (Romania, Transcaucasus) with preapical seta on t3.
