There seem to be sensilia on the second antennal segment. In that case the hairs on sternite 1 should be white (not black). Please check.

Yes the hairs of the sternite 1 are white.

I don't see it, but I believe you.

In that case, it is L. tessellans

Now, with a microscope, sternite 1 are with black hairs.

By means of the key:
-Back of the head on top without bristles.
-Tergites 3 and 4 with one pair of discal bristles each.

-Humeral callus ± reddish or yellowish, at least around the area of the outer humeral bristle.
Posterior edge of tergite 5 often with a reddish seam.
-Mouth edge less strongly pulled forward (by about the width of the 2nd antennal segment at
its end).

-Humeral callus predominantly yellow. Tibiae yellowish.

Now, I think L. olsufjevi.
