Compare with Milichiidae, Desmometopa.

Yes, that's what it is. We have two species m-nigrum and sordida. Must find out witch one this is. Thank You again Paul :)

Looks like a Phyllomyza female, probably of the P. securicornis group (see http://milichiida...curicornis). Females are difficult to identify.

Thank You Irina. In fact I tried to use the only key I have and there were no Desmometopa like this one.

Desmometopa has two lateroclinate orbital setae and Phyllomyza three. There is a key at http://milichiida...ilichiidae, but I need to improve it. Maybe one day I will find the time to do a Lucid key.

Without a good size indication and proper view of the frons it was enough for me to see that these were Milichiidae but to be not certain about genus. Hence I indicated to compare them with Desmometopa. I don't have all the characters in my head, but perhaps I will remember the orbital setae character now. ;)

Hi Paul, it is actually not so much the head setae I was looking at. The habitus is also different, with Phyllomyza being somewhat stouter. Also, there are no Desmometopa species with such long presutural dorsocentral seta. At least not in Europe.
