May be... The problem is: it is a male. Only females can be identified without fail, their genitalia are very typical. According to Falk (
https://www.flick...078290811/),
L. brevirostris has broad black streaks down the face and entirely yellow hind femora. The first character matches well, the second less. Van Veen (
https://home.hccn...ldius.html) says the snout should be blackish, which is not convincing here. Mielczarek (
https://www.resea..._in_Krakow) depicts a
L. brevirostris male without the black facial streaks and with the hind femora partially black. So what can we conclude? I adhere to "may be" - sorry!

Addendum: Because of the black frons, the decision is between
L. brevirostris and
L. signatus. So the odds are fifty-fifty to get the right name. Just label it "
L. cf.
brevirostris" with a note that it might also be the other species...
