This should be it, the prob. is that I can't find another image anywhere with such pterostigma on wings as on my image.

I think so. A colourful bee.
Its wing venation, colouration of the legs, abdomen resemble to this species.
I have also an image from East Turkey with the same features.

Hi!
Attention:
L. calceatum is virtually undistinguishable from
L. albipes after a photo ("twin species"
.

From Turkey, another similar species to calceatum gruppe, I think (attached). Could you please tell me the key characters between albipes and calceatum? Thanks. Muhabbet

Sorry, I'm no expert. I was only told by experts that my photos of
L. calceatum could also show (the rarer)
L. albipes. I think a microscopic examination is needed.

Check if labrum is black or yellow. Calceatum has black labrum and albipes yellow - I can not see which colour on the pictures. If labrum is yellow there are two species: albipes or euboeense, the latter one has shorter antennae (the bee on the third picture seems to have a shorter antennae, but is labrum yellow?) .......
Best regards

Many thanks Ebbek. I checked the colouration of the labrum of two species of mine. Labrum clearly black in my first image, and yellow in the second one.
Geographically, albipes is represented in Turkey only from Black Sea coast (very humid region), but euboeense is reported from Central and East Turkey (dry, cold mountainous climate). My second species comes from East Turkey; therefore, euboeense fits geographically better.

Yes, it seems quite clear that it is calceatum and euboeense. Significant for euboeense is shorter antennaea (each segment about 1,25 as long as broad, while albipes segments are at least 1,5 as long as broad) and euboeense also have well delepoded white hair patches on the first tergites which also is visible on your picture. In Sweden albipes is a common species, and we don´t have ueboeense so I have no further experience of tjhat species ... so it was interesting to see ...
