2023-08-28; Badem, RLP, Germany; 4 photos of "red" Mycetophilidae on foliage along my fencerow. Fly looks very much like Mycetophila cingulum but it does not have dark blotches mid-wing. NOTE: Post 3545 by kuv seems to be the same species & it has tentatively ID of Leia subfasciata. Thanks for ID help.

Hi Jim,
searching for "my" red Mycetophilid (s. https://www.dipte..._id=111810) I found a Russian Webaddress with the information "Species name(s): Mycetophila cingulum Meigen, 1830 = Leia bifasciata von Roser 1840 = Mycetophila lunulata Macquart 1834." (It a pity that Fauna Europaea isn't online). So I think we both look for the same ID ...
Greetings Kuv

Hello kuv,
thanks for the information (both our gnats look alike). I looked for Leia bifasciata & found photos on bugguide.net but that gnat also had dark blotches on the mid-wing. thanks & good luck

Hello again kuv,
It seems that Leia bifasciata is now normally called Leia bilineata. Hopefully a professional can help us.

Hi Jim,
after asking an expert I got a private message: "...This gnat is Leia fascipennis, a common species, which is often found on tree foliage. Most Leia including subfasciata have some dark markings on the abdomen and as was mentioned bilineata also has other marks on the wing. Mycetophila cingulum ... is quite unrelated, only resembling it in coloration but it also has dark markings on the abdomen and a spot in the middle of the wing ...".
Greeting Kuv

I'll agree with that since the wing veins are the same in the photos I've found. Thanks for your help with this ID.
