There are ventral spines on f3 (well visible on 1st picture), that speaks for
X. segnis.

Definitely not T scita, which has a spur on the hind femur which would be clearly visible in top picture if that's what it was.

I have to bring this old thread up as I have questions! ;)
I had a male on which the bristles in femur 3 looked much shorter than I see on X. segnis. The keys of Mark van Veen do not state there are no bristles on femur three, the couplet where it separates from X. segnis does state the ventral side of femur 3 is without long bristles but may be covered with scattered short black bristles.
The final account for the male X. tarda states for metatars 1 there is a long, white bristly hair hair dorso-apically which reaches to the apical margin of the 2nd tarsal segment. I can see this bristle in the first photo, my male also has it!
Surely this is Xylota tarda?
