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 Smile 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 TumbsUp

I've repeatedly tried to upload a photo with my thread but nothing is showing. I can't see that I've done anything wrong. Can someone please assist?

I might add that this is a great resource and I am really thankful for all the members help.

Thanks for the explanation Paul. It definitely stopped me from flooding the forum with my threads Wink

Each user has a maximum of ten new threads per day (24 hours). Just to prevent a single user from sending scores of his unidentified fly photos at once and thus drain out any other threads.

Hello, I'm having a problem posting new threads, as the "No new Threads allowed..." is showing up on all of the forums. Is there some sort of thread limit I've exceeded?

SabineH: you have to be logged in to see "New Thread" in the right upper corner of each "forum" site. In the case of accidental logout you have to start over.
