Hi Karsten, a male Thelaira solivaga, I think.
Greetings, Eric

Thelaira it is, but why solivaga ?
I don’t see an other vertical and I don’t see many strong ad on mid tibia.

I used the T&H key
Males solivaga: "...light side spots of the abdomen extended, clearly visible from above."
"dorsal hairs of tergites 3 and 4 fine, as long as 1/7 - 1/5 of the marginal bristles"
Males nigripes: "...abdomen usually appears dark when seen from above."
"middle dorsal hairs of tergites 3 and 4 as long as 1/4 - 2/5 of the marginal bristles"

The other characters are not clearly visible but may be present, I thought.
Greetings, Eric

Thelaira sp. (For example Thelaira nigripes: 2 anterodorsal setae bristles, Thelaira solivaga: 3-4 anterodorsal setae bristles on the middle tibia - They are twin species)

Regards
Lucyna

In Denmark, all Thelaira have so far been attributed to nigripes. if this one belongs to T. solivaga, it would be the first record nationally.

Carefully Wink . You need to be sure how many bristles there are on the middle tibia.

You should not only look for what you see, but also for ehat you don’t see (see my previous post). And I don’t think tha central dorsal hairs on tergites can be evaluated from these pics, yes the laterals can be done, but that is not what T&H are saying.

To me, this is either Thelaira spec or even cf. nigripes and the distribution seems to agree.
