Thanks, Paul, I'll have to revisit my key...
Any idea of the specie?

It's one of the dark-legged
Linnaemya sp. but I'd have to have the specimen to be able to identify it to species :)

Thank you, Chris. I have the specimen and can send you other pictures. Is there any specific angle that would be helpful?

Ahh, well ... dark-legged
Linnaemya are tricky. The features we need to see are not hard to locate but they are very small and very difficult to see. The first one is to look at Sternite-1 and see if it has pale hairs on it. Then we need to see the back of the head at the top where there are a load of pale hairs and in between those some rows of little black bristles and between the little black bristle sometimes there are some slightly longer bristles :D
These features just get you started in the key - there are more later on ;)
Sending it to me (or Theo) might destroy it if the post-men decide to play football with the parcels - but it would be the easiest way to get an identification ;) I think in northern Europe though pale hairs on sternite 1 would indicate
L.tessellans ... Theo might confirm that.
