Why albipuncta?
Halters - dark; t2 with ad; vien M curved forward at apex = Hydrotaea dentipes group.

Thanks for correcting me Nikita !

Why albipuncta?

If you do stupid things like me and read halteres but look at the calypters...
It annoys me how often I get it wrong even if I have decent images of the features in the keys Angry
It feels like my failure rate increases exponentially with the number of couplets in the key Frown

If I key it again in "The Muscidae of central europe" i do get to H. dentipes.

By "Hydrotaea dentipes group" do you mean dentipes in the key should/could be separated into different species ?

1. Leif, no reason to be upset when you took wrong way in keying. Everybody made and will make it a hell lot of times.
2. Well, females of H. cyrtoneurina and H. anxia may be excluded. H. similis and H. palaestrica - not. However, in 9 cases out of 10 it is H. dentipes.
