Thread subject: Diptera.info :: Agromyzidae - Cerodontha (Dizygomyza) -> fasciata

Hello,

This one keeps eluding me ... A fairly large, all black Dizygomyza: Orbits and abdomen without any yellow, only front femora narrowly yellow at the apex. Following Spencer (1976) I get to caricicola, but the genitalia obviously don't fit.
However if I use Papp & Cerny (2016) the species is luzulae which isn't recorded from Denmark (yet). But the genitalia seem to fit. Is it luzulae or if not, which one then?

As always from my malaise trap near Copenhagen. This time end of May 2018.

Any suggestions or help will be much appreciated.

All the best,

And for good measure - the ejaculatory apodeme.

Thank goodness! No new species :) Even though the orbits are very dark. Not the slightest yellowish and perhaps not even brownish, but alcohol can be tricky in that way.

Thanks, Milos |t
