I found this species in National Parc Hoge Kempen, Belgium
Dry area with heathland. Attracted to light.
Date : 09-09-2020
Is this Dolichopus simplex ?

Ok. Thank you Igor.

After your answer I was looking at this key :

https://diptera.info/downloads/Grichanov_N_Europe.pdf

but I'm a bit stuck on page 114 after number 10 - Antennal scape and pedicel reddish yellow at least beneath .

Any help is welcome.

Best regards

At least scape (1st segment) distinctly yellow. It is Tachytrechus notatus female quite probable, commonest species in Europe.

In Belgium, it is most likely T. notatus or T. insignis. Check Assis Fonseca (1978) or Parent (1938) for this. Both keys are available online.
