Hi, as I go trough my Muscidae I have problems again. I believe this is a Helina male and as I use the Central Euroean key it goes like: meron bare below posterior spiracle, prosternum bare, frons narrower than 1,9 times width of flagellemore, radial node is setulose undersides of wing, scutellum is finely haired beneath (Anthomyiidae like) and ad setae on hind tibia much shorter than hind basitarsus. Now we would have two species to make a choice and both are missing from our list; Helina decipiens or moedlingensis. So I went wrong somewhere but where this time ?? Is this Helina at all ?

I think it's Helina inded, but it is difficult to help you without the specimen in hands. If you send it to me, I would perhaps be able to tell more about it.

I have to say : very good hunch ! The meron is not bare at all, and if it is not conspicuous on the picture above, the sternite5 is really proeminent and bears long and dense hairs under the lens !
