Also rather small size, 6mm I think.

Great photos. I work on Sciomyzidae in the US but carried out my PhD on these flies in Europe. The darker specimen of the four certainly looks to be a Pherbellia. The other specimens could also be Pherbellia or Anticheta, Colobaea or Pteromicra. I would be happy to take a look at the specimens if you want to post them to me.

If the propleuron has small hairs and not a distinct seta above the base of the forecoxa, the specimen is likely to be Anticheta. If there is a seta but no hairs and the anal vein does not reach the wing margin the fly is likely to be Colobaea. If a seta is present on the propleuron and the cheeks are very narrow you ve probably got a Pteromicra (these guys also have small wings). Cheers

I thought that Sciomyzidae (1) is Tetanocera sp. Not?

Excuse me , Kahis. I meaned that Tetanocera is Sciomyzidae (1) = http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=1853#post_7574.
You mean that Renocera is this one (N4 by Black numeration) or N1?

An easy way to determine Renocera from other sciomyzids is to have a look at the middle femur. If there is a forward pointing bristle towards the centre it s not Renocera. If the bristle is absent it probably is this genus. The Renocera I ve seen tend to be larger than 6mm though.
